Abstract Objective: To assess the association between temporomandibular disorder (TMD) with sociodemographic factors, health-related factors, and oral conditions in adolescents. Material and Methods: This cross-sectional study was developed with 89 adolescents between 13 to 18 years. TMD diagnosis was obtained by the Research Diagnostic Criteria for Temporomandibular Disease (RDC/TMD) Axis I. Diagnoses of chronic pain, depression, presence of non-specific physical symptoms, including pain and anxiety, were obtained by the RDC/TMD Axis II. The feeling of happiness was measured by the Subjective Happiness Scale. Socio-economic and demographic characteristics were collected through self-administered questionnaires. Patients were examined for dental caries, dental trauma, malocclusion, and tooth wear. Parents answered a sociodemographic, economic, and general health questionnaire. Data were submitted to descriptive statistics, and a logistic regression model was used to assess the association between TMD and the socio-economic, demographic, health-related, and clinical variables. Results: TMD prevalence was 42%. TMD was associated to skin color (p=0.040), use of medications in the past year (p = 0.020) and previous dental trauma (p=0.030). Also, it tended to be associated with the presence of probable awake bruxism (p=0.053). Conclusion: Sociodemographic factors, health-related factors, and oral conditions play a role in TMD, with nonwhite adolescents, those who had used medications in the past year and/or had previous dental trauma having a greater chance of present this disorder.

ABSTRACT Objective: To evaluate the satisfaction of adolescents undergoing dental treatment between 2016 and 2018 at the Dental School of the Federal University of Minas Gerais (FAO UFMG). Material and Methods: A descriptive cross-sectional study using the Oral Health Services Satisfaction Assessment Questionnaire (QASSaB). The structured questionnaire has eleven questions divided among the dimensions: dentist / patient relationship, relationship with other professionals, effectiveness, accessibility/availability, technical-scientific quality, cleanliness and physical environment, acceptability, effectiveness/resolution, each with five response options. Descriptive data analysis was performed using absolute and relative frequencies. Results: A total of 145 adolescents participated in this study, 60 males and 85 females; 74.85% of adolescents rated dental treatment received as excellent, 76.7% reported having no symptoms after treatment, 46.2% considered it easy/very easy to get treatment, 65.6% reported that waiting time was short/very short, 90% considered dental equipment modern/very modern, 98% regarded the cleanliness of the waiting room and bathrooms as being excellent, 83.4% reported that they always received an explanation about the treatment, and 51.57% were totally satisfied with the appearance of the treated teeth and their chewing capacity. Conclusion: It was possible to observe that the adolescents, users of FAO UFMG, were satisfied with the service in the studied dimensions: human relations, effectiveness, accessibility/availability, technical-scientific quality, physical environment/cleanliness, acceptability and resolvability/effectiveness.

Abstract The aim of this study was to assess the factors associated with dental pain in adolescents from the state of Minas Gerais, Brazil. Individual data on adolescents aged 15 to 19 years were collected from the SB Minas survey secondary database. Dental pain over the past 6 months, assessed by a questionnaire, was used as the dependent variable. Sex, income, skin color, prevalence of untreated dental caries, periodontal health, dental treatment needs, and time of last dental appointment were analyzed as individual covariates. Allocation factor, Human Development Index (HDI), Gini coefficient, illiteracy rate, unemployment, 50% and 25% of the Brazilian monthly minimum wage, primary healthcare coverage, oral health team coverage, access to individual healthcare, and supervised toothbrushing average rate were the analyzed contextual variables. A multilevel analysis was conducted for the individual and contextual variables. Statistical analyses used hierarchical linear and nonlinear modeling to infer an association between the different levels. Male adolescents had a lower prevalence of dental pain (OR = 0.53; 95%CI = 0.37–0.75). There was an association between dental pain and low income (OR = 1.58; 95%CI = 1.07–2.33), prevalence of untreated dental caries (OR = 1.25; 95%CI = 1.11–1.40), periodontal health (OR = 1.80; 95%CI = 1.04–3.09), and dental treatment needs (OR = 6.93; 95%CI = 3.96–12.14). Sociodemographic and clinical factors at the individual level were associated with the outcome but not with contextual variables. These findings reinforce the need to address these factors for effective community health actions.

Abstract The aim of this study was to evaluate the factors associated with toothache in the adult population of Minas Gerais, Brazil. Individual data from a population sample (age 35 to 44 years) were collected from a secondary database of the SB Minas survey. Sampling was carried out by clusters and with multiple drawing stages. The eligibility criteria were to reside in areas chosen for the research, be within the age group, and accept to participate in the research. The individual variables assessed by a questionnaire and dental exams were sex, income, race/skin color, root caries, periodontal condition, need for dental treatment, and last dental appointment. The contextual variables, assessed by municipal indexes, were Human Development Index (HDI), illiteracy, unemployment, half minimum wage, quarter minimum wage, oral health team coverage, access to individual health care, and supervised tooth brushing average. The dependent variable was toothache in the past six months. A descriptive analysis was made using the Statistical Package for the Social Sciences and Hierarchical Linear and Nonlinear Modeling Software was used to perform the multilevel analyses for individual and contextual levels. An association was found between toothache and low income (OR = 2.00; 95%CI = 1.32–3.13), dental caries (OR = 1.86; 95%CI = 1.22–2.86), periodontal condition, and living on a quarter of the minimum wage or less (OR = 1.03; 95%CI = 1.00–1.08). Clinical and social factors were associated with toothache, reinforcing the need to improve public polices in oral health focused on the adult population.

Resumo Objetivou-se avaliar a atenção secundária em endodontia em um Centro de Especialidades Odontológicas (CEO) de Belo Horizonte (MG). A coleta de dados utilizou dois formulários: (1) sobre o tratamento endodôntico, preenchido pelos endodontistas; (2) sobre o tratamento restaurador, com dados dos prontuários. O programa SPSS 19.0 foi utilizado para analisar os resultados por meio de frequência e percentis. Foram finalizados 452 tratamentos endodônticos em pacientes adultos. Os pacientes apresentaram mediana de 39 anos de idade, a maioria era do sexo feminino (69,7%) e apresentou guia de referência da atenção básica (96,2%). A maior parte dos tratamentos endodônticos foi realizada em pré-molares superiores (23,7%), seguida de molares inferiores (22,3%), utilizando técnica mista (74,1%) e em única sessão (64,2%). O encaminhamento para o tratamento restaurador foi para o CEO em 81,2% dos casos e finalizado em 24,1% casos (n = 109). A contrarreferência após o tratamento restaurador ocorreu em 58,7% dos casos finalizados. É necessário um planejamento conjunto do tratamento odontológico entre a atenção básica e secundária e, dentro desta última, entre as especialidades, além de um adequado processo de referência e contrarreferência, visando garantir a integralidade do cuidado e a eficiência e eficácia do serviço.

Abstract This study aimed to evaluate secondary endodontic care at a Dental Specialties Center (DSC) in Belo Horizonte, MG. Data collection used two forms: (1) on endodontic treatment, completed by the endodontists (2) on the restorative treatment, with data from the medical records. The SPSS 22.0 program was used to analyze the results using frequency and percentiles. In total, 452 endodontic procedures were completed in adult patients. The patients had a median of 39 years of age, most were female (69.7%) and had a primary care referral order (96.2%). Most endodontic treatments were performed in upper premolars (23.7%) followed by lower molars (22.3%), using a mixed technique (74.1%) and in a single session (64.2%). The referral for restorative treatment was for the DSC in 81.2% of cases and finished in 24.1% (n = 109). The counter-referral following restorative treatment occurred in 58.7% of the completed cases. It is necessary to jointly plan the dental treatment between primary and secondary care and, within the latter, among the specialties, in addition to an adequate referral and counter-referral process aimed at ensuring comprehensive care and efficient and effective service.

Abstract: This cross-sectional study aimed to evaluate the asynchronous dental teleconsulting of Telehealth Brazil Networks Program in Minas Gerais. Data were collected from secondary databases of the Clinical Hospital of the Universidade Federal de Minas Gerais (CH/UFMG) and Medical School of UFMG (MS/UFMG), from July 2015 to July 2017. The variables analyzed were telehealth center, sex and profession, date and time questions and answers, response time in days, whether the issue was duly addressed, whether the teleconsulting was attended, post status, professional's satisfaction, conduct adopted after teleconsulting, dental specialty area, and type of issues. Sociodemographic data from the Intermediate Geographical Regions (IGR) of Minas Gerais, including the Municipal Human Development Index (MHDI) and Gini Index were also collected. The results were analyzed using SPSS v.22.0. In total, 3,920 teleconsulting were recorded, with increasing demand in the study period. Most were requested by dentists (93.3%) and female professionals (78.6%), during office hours (78.6%), and related to general conducts (72.1%). Almost all were attended (99.7%), with a maximum response time of two days (75.0%). A low feedback on satisfaction and resolution of issues (missing data of 57.2% and 70.2%, respectively) was recorded. Only 5.2% had information on whether patients were referred. The most common inquires were of issues about Pathology/Stomatology specialties (19.0%) and Pharmacology/Anesthesiology (18.8%). The response occurred within the expected time, with prevalent issues in basic dental areas and general conducts. Feedback from professionals must be encouraged to allow a better analysis and improvements of the program.

Abstract The aim of this study is to investigate the relationship between the epidemiological and clinical profiles of patients before and after hematopoietic stem cell transplantation (HSCT) and the need for endodontic treatment. The subjects included 188 individuals enrolled in the dental care program for transplanted patients of the School of Dentistry, Federal University of Minas Gerais (Faculdade de Odontologia da Universidade Federal de Minas Gerais, FO-UFMG) from March 2011 through March 2016. The patients were subjected to an HSCT conditioning dental regimen based on a thorough clinical and radiographic evaluation. Intraoral periapical and bite-wing X-rays were obtained, and after evaluation, specific dental treatment was planned and performed. The following demographic and clinical data were collected from the patients’ medical records: age, gender, transplantation stage, primary disease, transplant type, medication used, complete blood count at the time of visit, and need for endodontic treatment. The Kolmogorov-Smirnov and the chi-square tests were used. Leukemia (31.3%) and multiple myeloma (17.9%) were the most prevalent primary diseases. Most patients were subjected to allogeneic-related transplantation (83.6%). Most patients exhibited platelet counts and hemoglobin concentrations below the reference values in the pre-transplantation stage, while the neutrophil and platelet counts and the hemoglobin levels were within the reference ranges in the post-transplantation stage. The proportions of individuals requiring endodontic treatment were similar between the pre- and post-transplantation groups: 24.3% and 24.7%, respectively. The systemic conditions of the patients referred for dental treatment were compromised.

OBJECTIVE: This study identified which regions of ProTaper instruments work during curved root canal instrumentation. MATERIAL AND METHODS: Twelve ProTaper instruments of each type, S1, S2, F1, and F2, were assessed morphometrically by measuring tip angle, tip length, tip diameter, length of each pitch along the cutting blades, and instrument diameter at each millimeter from the tip. Curved canals in resin blocks were explored with manual stainless steel files and prepared with ProTaper instruments until the apical end following four distinct sequences of instrumentation: S1; S1 and S2; S1, S2, and F1; S1, S2, F1, and F2. Image analysis was employed for measuring canal diameters. The diameters of the canals and diameters of the instruments were compared. Data were analyzed by one-way ANOVA and Tukey's test. RESULTS: No statistically significant difference was found between the canals and instrument diameters (p>0.05). The largest diameters in the end-point of the instrumented canals were obtained with F1 and F2 instruments and in the initial and middle thirds with S1 and S2 instruments. CONCLUSIONS: All instruments worked at the tip and along their cutting blades, being susceptible to fail by torsion, fatigue, or the combination of these two mechanisms.
