ABSTRACT Objective: To test possible associations between Oral Health Literacy (OHL) level and socioeconomic covariates among users of Centers for Dental Specialties (CEOs). Material and Methods: The Health Literacy in Dentistry (HeLD-14) instrument was applied to 130 adult users of CEOs located in 13 municipalities in the state of São Paulo - Brazil, as well as socioeconomic issues. The researcher applied instruments in a specific room after randomly selecting individuals in the waiting room and invitation acceptance. Each item was ranked on a 5-point scale, ranging from 0 to 4, in which high scores indicate minimal difficulties in performing functions (high OHL) and low scores indicate very limited abilities to perform functions (low OHL). Statistical analysis using the Levene test was used to verify the possibility of using the one-way ANOVA test, and in case results show positive values (p>0.05), the Kruskal Wallis test was used. Results: The average age of participants was 45 years, with more than half being female (68.7%) with 9-11 years of schooling (48.4%). When considering the total value of HeLD-14 questions, OHL was associated with covariates schooling, marital status and family income. Conclusion: OHL levels were associated with socioeconomic variables, contributing to evidence in this field of specialized care.

Abstract The objective of this investigation was to compare the accuracy of mandibular measurements using a stabilizer (MS) with gold standard computed tomography (GS) images. Sixty mandibles were studied. Werth TomoScope HV Compact® was used to obtain CT images (GS), and the MS was also used. Analysis of the CT scans was performed using the VG Studio Max software® (Volume Graphics GmbH, Heidelberg, Germany), and MS was used after the proper positioning of the mandible. Descriptive and paired t test measures were used, and a ROC curve was calculated, as well as sensibility and specificity. MedCalc and STATA 13.0® were used (95% level of significance). Bicondylar breadth, bicoronoid breadth and minimum ramus breadth reached the highest concordance correlation coefficients at 0.99 (0.99-1.00), 0.99 (0.99–1.00) and 1.00 (0.99–1.00), respectively. Comparing observers with GS, the lowest accuracy was noted for the maximum mandibular length [0.59 (0.45–0.69), 0.64 (0.51–0.74)], the breadth of the right (0.14 (0.04–0.23), 0.14 (0.004–0.24)) and left mandibular body [0.14 (0.03–0.24), 0.16 (0.05-0.26)], and the right [0.58 (0.45–0.69), 0.63 (0.51–0.73) and left (0.59 (0.45–0.70), 0.59 (0.46–0.69)] mandibular angle. Various measurements exhibited good sensibility for males using MS: maximum mandibular length (78.12), bicondylar breadth (78.12), left mandibular notch breadth (84.37), and the left height of the mandibular body at the mental foramen (75.00). High specificity in discriminating females was observed for the left maximal ramus height (85.19), mandibular length (85.71), bicoronoid breadth (96.43), right height of the mandibular body at the mental foramen (82.19), bimental breadth (78.57), breadth right (92.86) and left (96.43) mandibular body, minimum ramus breadth (89.29), and left mandibular angle (85.71). MS was able to discriminate sexual dimorphism.

INTRODUÇÃO: após a promulgação da Lei nº. 8.078, de 11 de setembro de 1990, o Código de Defesa do Consumidor provocou importantes alterações no cenário jurídico brasileiro, proporcionando um maior equilíbrio nas relações estabelecidas entre os consumidores e os fornecedores de produtos e serviços. A partir dessa lei, os cirurgiões-dentistas passaram a estabelecer com seus pacientes uma relação de consumo. OBJETIVO: tecer considerações sobre a natureza obrigacional do cirurgião-dentista especialista em Ortodontia. CONCLUSÃO: a responsabilidade do contratado será compreendida entre os riscos previsíveis e as obrigações assumidas. Quando o profissional alerta de forma correta, clara e expressa, diminuem-se as chances de serem posteriormente cobrados.

INTRODUCTION: After the enactment of Law 8078, of September 11, 1990, the Consumers Defense Code implied important alterations in Brazil's legal scenario, providing a greater balance in the relationship between consumers and service providers. From this law, dental surgeons came to establish a consumer relationship with their clients. OBJECTIVE: Due to the ethical and legal issues against the dental professionals, this work makes general considerations about the nature of the dentist´s obligation in services, specifically in Orthodontics. CONCLUSION: The responsibility of the professional shall be restricted to predictable risks and undertaken obligations. When the professional warns the client in a correct, clear and express manner, it will lower the chances of being later charged.
