The teaching/service integration in terms of a process of reorientation of practices in service, alows better serve the bring the University of reality of the health service. Objective: The aim of this study was to discuss aspects of the teaching/service integration Dentistry in Brazil and analyze the perceptions of managers and preceptors dentists about the teaching/service integration. Methods: This is a qualitative study in which was conducted a literature review from literature survey in the databases of the Scientific Electronic Library Online (SciELO) and LILACS, using keywords: Teaching/Service integration; Curricular training; Dentistry; Education Program for Health at Work; PET-Health; Primary health care; Professional practices. In addition, was used a guide script for four managers and another for seven preceptors of Work Health Education Program (2010-2012) and of Extramuro Intership in Health Promotion II (2012) in the course of Dentistry of the Federal University of Espirito Santo. For data analysis, was used The Thematic Content Analysis proposed by Bardin that revealed four categories: teaching and learning, contributions to the service, interpersonal relation and professional formation. Results: Professionals noticed as satisfactory teachingservice integration and highlighted the exchange of experiences between professionals and academics as an important aspect. Also reported that there is enrichment of the academic training of future dentists, practice experience of reality in the training field, stimulate productivity in underserved areas, such as educational activities, and good acceptance by users. Stated, however, that there are limitations, such as those related to infrastructure and overhead professional. Conclusions: The study allowed from the perception of professional participants and the literature, the teaching-service integration is seen as a driver for change processes in the formation, and that the UHS is a privileged and fundamental space for such training and knowledge exchange.

Introduction: The proposal of the Continuing Health Education (EPS) implemented in Brazil, highlights the importance of the educational potential of the work process for transformation. The implementation of EPS in basic care is important due to the need to guarantee the universality and integrality of the Unified Health System, since it is a space of collective construction in which the different subjects are involved in health care. Objective: Analyze the perception of oral health aides and technicians (ASBs/TSBs) on the National Policy of Continuing Education in Health implemented for the oral health teams of the Greater Metropolitan Region Vitória, Espírito Santo, who worked in primary care between 2007 and 2012. Methodology: a qualitative approach, where the construction of the data was performed through a focal group. The discussion between the subjects of the research during the focal group was recorded and transcribed in full and in a literal form, where it was analyzed according to the Thematic Content Analysis. Results: ASBs/TSBs do not understand EPS and do not visualize it in practice in service. They see it as quick and punctual courses. They mentioned that courses and wheels used to happen more often. They cited the high number of appointments which made it impossible for the absence of the office and participation in other activities, the devaluation of the profession, and the priority for dentists. They observe the influence of the management and the commitment in the divulgation of the courses and the professional interest in participating. Conclusion: The ASBs / TSBs do not see the implementation of this policy in their day to day nor in their place of work, associating this lack to: lack of time, devaluation of the profession, management of the unit and the choice of the professional himself.

Introduction: The National Policy of Continuing Education in Healthcare (PNEPS) aims at the transformation of work in healthcare, stimulating critical, reflexive, committed and technically effective action of professionals understanding regional characteristics and the specific training needs of workers. Objective: Analyze the results and consequences of the implementation of PNEPS for oral health teams of the Great Vitoria Metropolitan Area (RMGV), Espirito Santo (ES) State in Brazil, who worked in primary care, among years 2007 to 2012, according to dentists and local coordinators of oral health. Methods: This is a qualitative research, which the data was formed by a focus group with professionals working in RMGV-ES, providing the evaluation of the research participants impressions: three local oral health coordinators and seven dentists, who discussed the PNEPS implemented in RMGVES, a semi-structured questionnaire. The discussion of the focus group was recorded, transcribed and was subjected to content analysis. Results: Data analysis revealed signs or clues that could support the discussion of the factors involving PNEPS implementation in RMGV-ES, pointing out the strategies undertaken and the initial organization, as well positive or negative factors. The relevance of this macropolicy was noticed as a tool to transform and qualify health workers practices and the effect of micropolicy in the work process of oral health teams was also noticed. However, some barriers remain and they have to be overcome in the forming process, the management, the clinical and technical work process and the social control. Conclusion: There is need to address learning models that contribute to improve dentists development and at the same time can provide changes in practices and health work processes, with its reorganization and strengthening, which will be possible through the PNEPS improvement.
Abordagem em saúde pública da associação do conhecimento, condição periodontal e controle glicêmico de pacientes diabéticos tipo 2
(Universidade Federal do Espírito Santo, 2018-02-06) Valentim, Flavia Bridi; Rosetti, Elizabeth Pimentel; Pacheco, Karina Tonini dos Santos; Barbosa, Alice Pfister Sarcinelli
Background: Periodontitis control aids to prevent and control the diabetes mellitus (DM) and the understanding of this relationship has the potential to cause changes health policy. Aim: To verify, in diabetic patients, oral hygiene habits; referral, attendance and dental care history; self-observed mouth clinical features that may be related to periodontitis manifestation; DM glycemic control and its relationship with periodontitis; knowledge of periodontal disease (PD) and its relationship with DM. Methods: A crosssectional epidemiological study was conducted with 288 patients with type 2 DM of both sexes, nonsmokers, aged ≥18 years and with at least one tooth. A validated structured questionnaire was used to data collection. In a second moment, only the 216 patients who had recent blood tests with glycated hemoglobin (HbA1c) were selected from the total sample. Adequate DM control was considered with HbA1c ≤7%. Descriptive statistical analysis and simple and multiple logistic regressions were performed. Results: For the study population, more than 90% of the patients reported brushing their teeth twice a day or more; more than 60% reported having visited a dentist in the last year; approximately 80% have already undergone PD treatment; the medical referral rate for dental treatment was between 13 and 15%; and about half of the patients had periodontitis. Patients with higher education level, who flossing daily, with periodontitis and who received treatment for this disease were more likely to have received information on what is PD (p <0.05; OR> 2). Patients with higher education level and longer DM diagnosis had a greater chance of being told about the relationship between PD and DM (p <0.05; OR> 2). Of the 216 patients who had a blood test with HbA1c rate, 59.72% had controlled DM. No significant association was observed (p=0.603) between HbA1c control and presence of periodontitis. For the patients with periodontitis, there was also no association between HbA1c control, being told about PD (p=0.921) and know about the relationship between PD and DM (p=0.650). Conclusion: The diabetic patients of this study had adequate oral hygiene habits, frequency of care and dental treatment, but only the smallest part of the sample received medical referral to the dentist. It was observed a relationship between the knowledge of PD and its relationship with education level, oral health and dental treatment. No relationship was found between periodontitis and glycemic control of DM.

Misfit at implant-abutment joints (IAJ) may compromise the perimplant tissues health. Intraoral radiograph are an complementary diagnostic method to misfit detection and an orthogonal relation between the central beam, the implant, and the radiographic film is indicated. The aim of this study evaluated the accuracy of 4 intraoral radiographic techniques on the detection of gaps at IAJ. Twenty implants were placed in prototyped jaws and UCLA-type abutments with metal collar were installed. Different gaps were simulated by placing one or three 50-μm-thickness polyester strips at the IAJ, and the absence of the strip represented the control group (no gap). Periapical radiographs with different film-holders were taken for each technique: bisecting, interproximal, parallel-cone and modified-parallel-cone (with a custommade paralleling index). A total of 240 digital radiographs were evaluated by 4 specialists in dental implants. The ROC curves (Az) and Fisher’s Exact comparison tests were performed at a significance level of 5%. Diagnostic values (sensitivity, specificity, accuracy, positive, and negative predictive values) were also obtained. The Kappa test was used to assess intra- and inter-evaluator reproducibility, which ranged from substantial to almost perfect, and moderate to substantial, respectively. All diagnostic values were lower for the bisecting technique for both 50- and 150-μm gaps. Az values for the bisecting technique were significantly lower than those obtained for the other 3 techniques (p<.05), which did not differ from each other. The 150-μm gaps were more easily detected than 50-μm gaps only for the bisecting technique (p˂.05). The interproximal, parallel-cone and, modified-parallel-cone techniques were the most accurate to detect misfits at IAJ. The bisecting technique should not be clinically indicated for this purpose.

Introduction: Mouth breathing pattern in children may have negative physical, psychological and social effects according to the intensity and duration. The relationship between mouth breathing and sleep-disordered breathing (SDB) is derived from clinical conditions ranging in increasing severity from primary snoring, to upper airway resistance syndrome and obstructive sleep apnea syndrome. The main cause of mouth breathing and SDB is associated to narrowing of the upper airway in varying degrees. This association is of concern due to its immediate or late clinical implications like disturbances in craniofacial growth, behavioral changes, impaired learning and cognitive functions, negatively influencing quality of life. Objective: Assess the prevalence of mouth breathers (MB) and the presence of facial anatomical changes that affect children with SDB, in addition to assessing self-perceived quality of life of MB. Methodology: A cross-sectional observational sample of 687 students from public schools, aged 6-12 years old, evaluated by medical history, clinical examination and lip seal tests. Self-perceived quality of life of MB was obtained through questionnaire (Ribeiro, 2006). Results: In the total sample, 520 (75,7%) students were nasal breathers and 167 (24,3%) were MB. Among MB, 40,1% had obstructive hypertrophy of the palatine tonsils, 26,4% had Mallampati score III and IV, 35,3% has excessive overjet, 23,4% had anterior open bite, 15,6% had posterior crossbite, 53.9% had atresic palate, 35.9% had interlabial gap, 31% reported problems related to sleep and 9,0% reported having the feeling of stop breathing while asleep. Conclusion: The prevalence of facial anatomical and functional changes in mouth breathers students was high, however the self-perception of quality of life was considered good. It is recommended the adoption of public health policies aimed at diagnosis, counseling and treatment of students at this age group, in which the relief of signs and symptoms can promote normal craniofacial growth and reduce future risk of SDB.
Análise da condição peri-implantar e da microbiota subgengival de implantes com diferentes conexões : estudo transversal após 5 anos de carga funcional
(Universidade Federal do Espírito Santo, 2017-09-29) Costa, Bianca Scopel; Feitosa, Alfredo Carlos Rodrigues; Guerra, Selva Maria Gonçalves; Fardin, Vinicius Pavesi; Bertollo, Rossiene Motta
The union between the implant and the prosthetic intermediate occurs through different connections, which present distinct characteristics, highlighting microgap width and mechanical stability. The aim of this study was to analyze the peri-implant condition and to compare the subgengival microbiota of implants with different connections, after at least 5 years of functional load. A cross-sectional study was carried out involving 30 implants installed in 16 healthy periodontal individuals, divided into three groups according to the type of connection: Group A - External Hexagon (n=14), Group B - Tri-Channel (n=9) and Group C - Morse Cone (n=7). All patients underwent clinical evaluation and the composition of the subgengival microbiota was analyzed using the Checkerboard DNA-DNA Hybridization technique, from samples of the subgingival biofilm. The clinical variables were analyzed by the Fisher Exact test, except for the probing depth variable that used the Kruskal-Wallis test, the same test was used to analyze the count (x106 ) of the DNA probes of the 40 bacterial species present in the biofilm samples. The clinical parameters index of visible plaque and bleeding on probing presented a high percentage in all types of connections (p˃0,05). The bacteria Treponema denticola, Fusobacterium nucleatum (sp. vincentii), Prevotella nigrescens and Prevotella intermedia are present at high levels in group A, while Group B presents high levels of Porphyromonas gingivalis, Tannerella forsythia and Fusobacterium periodonticum (p<0.05). Group C had a low count of pathogenic bacteria. The study concluded that the type of prosthetic connection did not influence the peri-implant clinical parameters, but it influenced the bacterial colonization of the subgingival biofilm.
Análise da expressão de Patched e distribuição de mastócitos em tumores odontogênicos ceratocísticos
(Universidade Federal do Espírito Santo, 2014-12-18) Milholli, Ana Flávia Lagassa; Barros, Liliana Aparecida Pimenta de; Coburn, Karla Loureiro Almeida; Spohr, Tânia Cristina Leite de Sampaio e
The Keratocystic Odontogenic Tumor (KCOT) is an intraosseous benign tumor, which displays aggressive behavior, with a tendency to local destruction and infiltrative and recurrent potential. It is also one of the manifestations of the Nevoid Basal Cell Carcinoma Syndrome (NBCCS). Evidence shows that the patched gene may be a significant factor in the development of KCOTs by having their activity inactivated. The aim of this study was to perform a comparative analysis between sporadic and syndromic KCOTs by checking the expression pattern of Patched protein and the distribution pattern of mast cells. Twenty-eight specimens of KCOTs recorded in Anatomic Pathology Service (SAP) of the School of Dentistry of the Federal University of Espirito Santo (UFES) during the period 2004-2012 were submitted to immunohistochemical technique to detect Patched protein and stained with Alcian Blue to detect mast cells. Histopathologic features were evaluated. All clinical data (gender, age, ethnicity and location of the lesion) were obtained from the files. For immunohistochemical analysis a score was adopted. Regarding the quantitative expression of patched, we found that 77.77% of KCOTs (syndromic and non-syndromic) showed immunostaining score of 4 (between 76% and 100% of cells stained). The basal and intermediate epithelial layers comprised most of staining compared to the surperficial layer. Only cytoplasmic staining was found. The histopathologic features were more evident in syndromic tumors, however, there was no significant difference in mean mast cells found to syndromic and non-syndromic tumors. Therefore, our findings demonstrated a strong epithelial expression of Patched in KCOTs, suggesting that this protein seems to be important for the pathogenesis of these tumors.
Análise da remodelação tecidual e da expressão de MMP-9 durante a erupção dentária

The tooth formation results from the interaction between the oral epithelium and the underlying ectomesenchyme. As these elements develop, ossification and tissue remodeling occurs around them, so that they are surrounded by a bone crypt. The tooth eruption is a complex process which depends on the release of several signaling molecules and growth factors that enable the tooth to cross tissue barriers in order to emerge into the oral cavity. Studies have shown intense bone remodeling around the developing tooth, consisting on bone resorption in the coronal area of the crypt, accompanied by bone formation in the basal area, promoting tooth movement. These events, followed by disruption of the connective tissue of the lamina propria, are essential steps of the eruptive movement and seems to be dependent of effector cells such as osteoclasts and mast cells, which release matrix metalloproteinases (MMPs) responsible for the degradation of the extracellular matrix of these tissues. This study aimed to carry out an analysis of tissue remodeling and MMP-9 expression throughout the eruptive process in rat molars. For this purpose, a histomorphometric analysis was conducted and included the measurement of bone surface area in the basal and apical area of the bone crypt, the quantification of the osteoclasts and mast cells and the expression of MMP-9 on the tooth germ and surrounding tissues. Our results demonstrated a reduction of bone area on the apical region of bone crypt, followed by a decreased number of osteoclasts lying on the bone surface. In parallel there was a progressive increase in bone area at the base of the bone crypt. High number of mast cells were quantified at the lamina propria of nine days old rats, and those cells showed cytoplasmic expression of MMP-9, suggesting a possible role of these cells in the recruitment of osteoclast precursors, whose peak activity occurs at that same time. The same expression pattern was also observed in osteoclasts, osteoblasts and osteocytes, suggesting a combined action of bone cells and mast cells in the cellular events that result in tissue remodeling during the eruptive process.

Background: The temporomandibular joint (TMJ) can be affected by the same pathological process as the other joints in the human body. Osteoarthritis (OA) is the most common temporomandibular disorder and it is characterized by the degeneration of the cartilage tissue and even the bone below. OA has a complex etiology and disordered occlusion is considered a risk factor because it can create a compression of the cartilage tissue leading to the expression of various cytokines and chemokines, such as the matrix metalloproteinases which activity is regulated by the tissue Inhibitors of the metalloproteinases (TIMP). Among the four existing types of TIMP, TIMP-1 is the most important because it can act as a signaling molecule independent of MMP inhibition thereby influencing important biological processes. Aim: To investigate the responses of mandibular condylar cartilage to experimentally induced disordered occlusion and to evaluate changes in the expression of the TIMP-1 molecule. Methods: Twenty-four female Wistar rats at the age of 8 weeks were enrolled in this study. The animais were randomly divided into experimental and control groups and further divided into four subgroups for two time points (2 and 4 weeks). Experimentally induced sagittal disordered occlusion were created by moving the first molars mesially and distalizing the third molars unilaterally and in opposite sides of the dental arches. At the end of two and four weeks, remodeling of the mandibular condylar cartilage was assessed. Protein expression of TIMP-1 were investigated by means of immunohistochemical staining. The quantitative analysis were made through an image software and statistical analysis by chi-square and Mann-Whitney tests were performed. The statistical significance was defined as P< 0.05. Results: In the 2- and 4-week experimental groups OA-like changes were observed. The most common changes were the increased thickness of the posterior third, disarrangement of the layers disposition, osteoclastic activity and osteophyte formation. Also were found cellular alterations that took form of pyknotic nuclei and condensed cytoplasm chondrocytes and characterize diminution of metabolic activity. The TIMP-1 expression was shown in the mature layers of the control group. However, in the experimental group, immunopositive cells were found in the proliferative and mature layers being that the posterior third of the 2-week experimental group presented a higher levei of TIMP-1-positive cells when compared to the correspondent control (P= 0.0291). Conclusion: The present results indicate that the experimentally created disordered occlusion led to degenerative responses accompanied by changes in the expression of TIMP-1 in mandibular condyle cartilage.

The first contact of students with Endodontics Dentistry School of the Federal University of Espírito Santo is in the fifth period of the course in the Discipline of Endodontics I. In it, students know the Endodontics principles: morphology, coronary access, root canal preparation techniques, disinfection and obturation of the root canal system. Learning occurs in previously extracted teeth before the academics have any contact with the endodontic clinic at the Discipline of Endodontics II in the following period. The aim of this study was to analyze through the clearing technique the canals were prepared during this Discipline (laboratory). The quality of the preparation chemical-mechanical techniques was examined concern the shaping of the root canal and compared the best result of the same, visualized the anatomical features of the root canal system, compared the radiographic exam of the teeth and clearing technique and also checked whether the students have assimilated the knowledge of Endodontics. The data collected were subjected to Binomial test,Kappa and Chi-square test. These showed that: the modeling of root canals analyzed by the clearing technique, 67% were modeled with a statistical significance of 0.002 (p<0.05), as the comparison between the preparation chemical-mechanical techniques used in relation to the relative frequency the variable modeling of the root canals was 65.9% when modeled channels prepared with step-back technique and 68.2% of teeth modeled when prepared by Oregon Modified technique (p=0.8206) with no statistically significant difference between techniques, and as the concordance of the results of variable modeling of the root canals between the radiographic examination (73.8%) and clearing technique (67%) yielded a Kappa value=0.511 showing a moderate agreement between the two visualization techniques. It was concluded that: the modeling of channels was satisfactory showing that students are assimilating the knowledge of the Discipline; radiography proved to be limited in view of the channel modeling and also in view of the anatomical features of the root canal system, and also that the clearing technique is a visualization technique accessible and essential to the development of education in the Discipline of Endodontics.

Introduction Classroom routine in higher education institutions is a field of work that constantly encourages studies, investigations and research towards a more prospective learning processes, not only students', but also professors' learning processes. Objective: This study aims at carrying out an exploratory, descriptive and explanatory investigation so as to analyze and describe the teaching-learning process in the professionalizing cycle of the Dentistry Program at the Federal University of Espírito Santo (UFES), Brazil, from the perception of students and teachers. Methodology: It is a quanti-qualitative, exploratory, descriptive and explanatory study. The sample comprised 60 professors at the professionalizing cycle departments of the Dentistry Program at UFES and students of the 7th and 10th term in the course. A semi-structured questionnaire and interview, based on Lazzarin (2005), Araújo a M ll (2011) C J ’(2008) instruments were employed in this study. The project was approved by the Research Ethics Committee CCS/UFES under registration no. CAAE 339550144.0000.5060. Descriptive statistical analysis (percentage rate) was performed using Statistical Package for Social Science for Windows (SPSS) and qualitative data (interview) were interpreted based on Bardin content analysis studies (2009). The variables analyzed were: teacher training; planning of lessons developed by teachers; interaction with students; needs work done by teachers; perceived difficulties in the work of the teachers; more effective learning experiences for students and students' attention in the lectures. Results: P ’ p l how that 91.1% of them hold an advanced postgraduate degree (doctorate) and 75.6% have had pedagogical training at some point of their postgraduate programs. The option for teaching was programmed by 91.1% of them, in which 77.8% worked as full-time professors. Data show that over 50% of participant professors have administrative, research/extension activities, besides their classroom work hours. The social-dental care needs in Brazil are understood by 95.6% of professors, and 51.1% of them believe that graduated professionals leave the course prepared to meet the l h B z l . I ’ p , h g q l y the Dentistry Program at UFES is rated as excellent by 43.6%, and most of them are satisfied (50.4%) with the graduate program, but feel discouraged by some facts. Practice classes were the most effective aspect by 50.4% among students. Among the professors interviewed, there is clear interest in participating by 91,1% in incorporated professional development programs to improve their teaching skills. Conclusion: In conclusion, the professor of dentistry course need to wake up to the need to reflect on their practices, because it continues favoring technical knowledge at the expense of teaching. Dentistry students show difficulties in demonstrating social sensitivity and concern for the problems of the population. The study is intended to alert the postgraduate courses of higher education institutions on the need to seek alternatives to qualify the professionals who make up the teaching staff of the institutions, which do not have adequate training for teachers. In the medium term, we plan to use data from this study to approach strategies and an intervention project, that allow improving the teaching-learning process and consequent background of students graduated in the Dentistry Program at UFES that positively impact the health care.

The aim of this study was to evaluate, using the clearifying technique, the quality in vitro of the root canal therapy of teeth prepared by students of the Endodontic Class from the fifth period of the Dentistry Course. There, the students learn all the subjects involving the root canal therapy: morphology, coronary access, instrumentation techniques, disinfection and obturation. They work in extracted teeth in the University laboratories before going to clinics in the next period. This research, also aims for the evaluation of the instrumentation technique with the best results, the efficacy of the X ray as a method to evaluate the result of the treatment and if the students are prepared to clinical treatment. The Binomial Test was used to statistics. The results showed that the formatting of the root canal system was satisfactory with 67% of positive results and 33% of negative results, and with significant statistics (0,014) (p < 0,05). The conclusion of this research was that the students learned the contents of the discipline and are capable to do the root canal therapy in vivo in the sixth period, although it is necessary more practical time in the in vitro treatment to increase the accuracy of the root canal therapy. The X ray was not a good way to show the students the result of the treatment. Although the clearifying technique was an excellent method of learning the anatomy and the in vitro root canal therapy, being necessary to improve the clinical knowledge of the students.

Magnetic field is a region of space where the magnetism is manifested, due to materials with magnetic properties - called magnets. The magnetic field therapy for various types of diseases has become common. The study aims to analyze the effects of the magnetic field on the healing of soft tissue wounds made on the backs of rats. It is a quantitative experimental study using 54 male Wistar rats of 120 days, weighing 250-300g were divided into three groups (C, E1 and E2), which were made in skin wounds in his back. The animals of group E1 were kept under the influence of the north pole of a magnet with magnetic field strength of 850G. The animals of group E2 were kept under the influence of the south pole of a magnet with magnetic field strength of 850G. In each of the periods (3, 7 and 15 postoperative days) were measured macroscopically the wound areas of the back, the microscopic distance between the healthy edges from histological and counting of inflammatory cells. The results showed that over the wound area group E2 showed higher values than group C and E1 in the periods of 3 and 7 postoperative days. In the same way, values for the distance between the healthy edges for the E2 group in periods of 3 and 7 postoperative days were higher when compared to group C and E1. The count of inflammatory cells was lower in both groups E1 and E2 compared to C, but more significantly to the group E2. It can be concluded that exposure to the magnetic field arising from the use of magnets intensity 850G may modify the process of inflammation and repair of tissue in the backs of rats.

The teaching-learning process has undergone many changes over the years, one of the reasons is to adapt to the generation of students from schools and universities. This adaptation has also been occurring in the curriculum of higher education courses, among them Dentistry. One way of recording such changes is the analysis of the pedagogical design of the courses (PPC) of Dentistry. In the PPC there is vital and important information about the purpose of the course, courses taken (compulsory and optional), as well as the methodologies that the teachers are using to teach. The objective was to verify the teaching procedures registered in the PPC of the Dentistry course of the Federal University of Espírito Santo (UFES) and compare it with the methodology cited by the professors of the professional cycle through a questionnaire. A documentary, exploratory, descriptive and quantitative study was carried out. In the documentary research, 50% of the subjects of the vocational cycle (5th to 10th period) registered in the PPC of the UFES Dentistry course were included, forming a total of 15 subjects. In addition, the professors of the vocational cycle of the UFES Dentistry course (5th to 10th period) were interviewed from three departments: Dental Clinic, Dental Prosthesis and Social Medicine that were randomly selected. In the first stage of the interview, three questions were asked related to the discipline, period and the teaching procedures used to teach; if the teachers remembered what procedures were mentioned in the PPC and if they could be mentioned. After this step, it was carried out the reading of the Topic Methodology registered in the PPC with the teacher. After this reading, the second part of the questionnaire was applied with questions related to the topic Methodology. The teaching procedure most frequently cited by teachers was the lecture, a traditional methodology. 93% of teachers and 83% of PPC subjects reported using it. The second procedure most cited by the teachers was the seminar reported by 40% of the teachers, in the PPC he was the most cited and was present in 91% of the subjects of the PPC. Six other teaching procedures were cited, such as bibliographic research, problem-based learning (PBL), directed study, study group, discussion and problem-solving. It was observed in this research that there is little diversity in the teaching procedures cited by the teachers interviewed and described in the PPC of Dentistry of UFES. It can be concluded that there is some pedagogical difficulty or deficiency on the part of teachers to adopt new teaching procedures, including interactive teaching procedures.

This study evaluated the type and location of defects on the surfaces of rotary instruments ProTaper® Universal before and after use in the preparation of root canals and compared possible shape changes resulting from its use files to prepare the canals with their original conformation. It was used 8 boxes of files of ProTaper® Universal containing: Sx, S1, S2, F1, F2, F3, F4 and F5 25mm long, divided into three groups. Group A before the use of the instruments. Group B afer the use of each set of the instruments to prepare three molars. Goup C instrumented with the same series, in two molars following the technique recommended by the manufacturer of instrumentation. Analyses were conducted in the following dimensional: length and angle of the tip, diameter and taper at various points along the rod and diameter D0; tilt angles of helices to the long axis of the instrument, the lengths of steps and length of the total helix. Furthermore, we evaluated the deformation of 3mm from the tip. Measurements were performed in a scanning electron microscope, according to the Specification ANSI/ADA n.101 (2001) in the three moments of the instrumentation in root canals. The values were analyzed by descriptive tests, Wilcoxon and t test. The result showed that the types of defects found in ProTaper instruments were marks and metal strips, sharp edges and blunt depressions. These defects were present on the surface of the files 3mm over the study. Before instrumentation in root canals, braking marks and strips of metal and sharp edges were more blunt observed in the first and third mm. After the instrumentation, the amount of files that had sharp edges and blunt depression progressed. There was a decrease in legth from the tip of the instrument ProTaper, as the angle increased at all times. The diameter remained within the limits of tolerance in some parts of the instrument shaft, along the experiment. The inclination angles of the propellers on some edges decreased, while the distance between the crests of successive helical stems increased at all the times. The length of the active part were below the recommended 16 mm and using inside the root canal, the values decreased. No instruments fractured during the experiment.
Análise e prevalência de lesões cervicais não cariosas e suas relações com interferências oclusais : estudo in vivo
(Universidade Federal do Espírito Santo, 2012-05-25) Castro, Christina Oliveira de; Xible, Anuar Antônio; Azeredo, Rogério Albuquerque de; Tavares, Rudys Rodolfo de jesus
The aim of this study was identify the presence of non-carious cervical lesions (NCCL), in a random sample of individuals and correlating with the presence of occlusal interferences, as well as the risk factors involved in its development. There were evaluated 180 patients from Federal University of Espirito Santo, of both genders, aged 18 to 70 years. Involving 5192 teeth, which were examined by four investigators and one of them a Gold Standard Examiner. Used two study designs: observational cross-sectional and case-control study. Sought to identify NCCL and occlusal interferences. A data collection instrument was established in order to correlate socio-demographic and oclusal factors. Examinations concerning the presence of NCCL were made with a periodontal probe. The occlusal aspects of individuals, such as centric relation (CR), the maximum intercuspation (MHI) and excursive movements were surveyed. Regarding the number of individuals with NCCL, it was found that 129 of them had teeth with NCCL. In the total number of teeth, had 702 with NCCL. The distribution of lesions for each group of teeth, the premolars showed higher frequency, followed by the molars. There were 546 with occlusal interferences, and the most affected teeth were the first premolars. There was no positive correlation between the presence of occlusal interferences and NCCL.
Análise epidemiológica, histopatológica e imuno-histoquímica de ameloblastomas : casuística de seis anos
(Universidade Federal do Espírito Santo, 2012-07-04) Rocha, Regina Furbino Villefort; Barros, Liliana Aparecida Pimenta de; Coburn, Karla Loureiro Almeida; Freitas, Vanessa Morais
Ameloblastomas are odontogenic tumors (OTs) derived from epithelium which etiology remains unknown. However, recent studies have identified molecular changes associated with the development and progression of OTs, including cell adhesion molecules like E-cadherin and beta-catenin. Objectives: to conduct an epidemiological investigation of ameloblastomas cases from files of the Anatomical Pathology Service at Federal University of Espírito Santo (SAPB-UFES), analyze their histopathological features and the expression of beta-catenin in different variants of ameloblastomas. Methods: a retrospective study of ameloblastomas registered at SAPB-UFES between March 2004 and December 2010. Sociodemographic, clinical and imaginological data were collected, as well as data about access, diagnosis, treatment and follow up of these patients. The histopathological analyzes were based on Vickers and Gorlin, Waldron and El-Mofty and the World Health Organization criteria. Primary antibody anti beta-catenin mouse monoclonal and indirect immuno-peroxidase technique was employed for immunohistochemical analysis. Intensity and location of the immunostaining were analysed. For semiquantitative analysis the scores were: negative, focal, variable and uniformity positivity. Results: there were 13 ameloblastomas, histopathologically classified as solid (06), unicystic (03) and desmoplastic (03). All of them were immunostained. The intensity of immunostaining ranged from weak to strong (1-3). The mean of immunostaining ranged from 10.82% to 13.38% in the nucleus; from 39.93% to 47.61% in the membrane; and from 90.01% to 98.53% in the cytoplasm. However, there was no significant difference in expression of beta-catenin between three different types of ameloblastomas. Conclusion: The results were similar to other epidemiological studies. The cytoplasmic expression of beta-catenin shows accumulation in the cytoplasm and suggests changes in the Wnt signaling pathway. Moreover, the reduction of membrane expression suggests changes in cell adhesion.

Introduction: A conservative approach for the treatment of large jaws cysts is the surgical decompression that can promote the reduction in intracystic pressure, and consequent reduction of the lesion and possible histopathological changes of the epithelial lining and fibrous capsule. Objective: Assessing the histological changes of the cyst lining of odontogenic cystlike lesions before and after decompression. Methods: The authors was performed a retrospective cohort study using histological data records and slides of cystic lesions underwent surgical decompression of patients treated in the discipline of Oral and Maxillofacial Surgery II and Oral Diagnosis Center of UFES between July / 2010 and July / 2016. Clinical and demographic data of patients were obtained and the histopathological changes of the epithelial lining of cysts underwent surgical decompression analyzed with the aid of Binocular Microscope Primo Star (Carl Zeiss). The data were compared using the McNemar test (p-value <0.05). Results: The sample included 10 patients and 11 cystic lesions, which are more prevalent in males (54.55%), with a mean age of 31.1 years and time of decompression on average 12.7 months. There was agreement on the final diagnosis with the initial diagnosis in 9 lesions (81.81%). After decompression some changes cystic capsule were significant as compared to the before decompression aspect: intense inflammation development (p = 0.0468), the distribution of inflammation focal (p = 0.04364), location of the inflammatory infiltrate subepithelial (p = 0.02334), justaepitelial (p = 0.04123) and perivascular (p = 0.04364). Conclusion: There was agreement between the initial and the final diagnosis in most lesions. Surgical decompression increase the intensity inflammation in the capsule and shows a tendency to increase the thickness of the epithelial lining of the cystic lesions.
