Association between Oral Health Literacy and Socioeconomic Variables in Users of Centers for Dental Specialties

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

Ethical and legal considerations on professional liability of the orthodontist

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.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.14615

Efeitos cefalométricos do Aparelho Bimetric de Wilson na correção da Classe II de Angle

Objetivo: avaliar a distalização e inclinação dos primeiros molares superiores além de analisar o efeito sobre a altura facial ântero-inferior, durante o tratamento da má oclusão de Classe II com o aparelho Bimetric de Wilson. Metodologia: foram avaliados os cefalogramas obtidos das telerradiografias laterais antes e após distalização de molares em 25 pacientes, tratados com o aparelho Bimetric de Wilson. A idade média inicial foi de 13,4 anos (+1,4). O tempo médio de distalização foi de 4,2 meses. As medidas foram testadas e repetidas quando dois fatores foram considerados, tratamento/aparelho (Bimetric) e avaliações (antes e depois) no mesmo paciente, por meio do teste estatístico ANOVA. Foi utilizado nível de significância de 5% (p 0,05). Resultados: a avaliação cefalométrica antes (T1) e pós distalização (T2) mostrou que o aparelho Bimetric de Wilson promoveu uma distalização dos primeiros molares superiores de 1,82mm, uma inclinação distal de 4,5° e um aumento da AFAI de 1,04mm. Conclusão: houve alterações nas medidas, embora sem significância estatística, nas quais a AFAI aumentou em 1,04mm. Os primeiros molares superiores distalizaram 0,43mm/mês e inclinaram-se distalmente 4,5°. Palavras-chave: Má Oclusão de Angle Classe II; Ortodontia Corretiva; Ortodontia/classificação

Validation of three methods for age estimation of Brazilian children and adolescents

A estimativa de idade é um importante recurso em Odontologia Legal. Entre as diversas formas de se obter uma estimativa de idade, pesquisadores podem fazê-la por meio da análise do estágio de mineralização dos dentes permanentes. Este tipo de análise, torna possível que uma simples radiografia panorâmica possa fornecer dados relevantes para identificar um indivíduo falecido, por exemplo. Este estudo propõe a validação, análise da acurácia e a construção de fórmulas baseadas nos métodos de Liliequist e Lundberg com a adaptação de Hägg e Matsson (LLH), Haavikko (HKK) e Mornstad et al. (MSW) para a estimativa de idade pelo estágio de mineralização dos dentes permanentes em crianças e adolescentes brasileiros. Para alcançar este resultado, foram selecionadas radiografias panorâmicas de brasileiros em uma amostra contendo 1.009 radiografias (387 do sexo masculino e 622 do sexo feminino) com idade entre 8-15,99 anos. Destas radiografias, foram selecionadas apenas as que cumpriram com todos os requisitos dos critérios de inclusão e exclusão. Após a aplicação das metodologias, os resultados foram inseridos e trabalhados no Programa Excel, Pacote Estatístico STATA 13.0. (StataCorp LP, College Station, Texas, EUA) e MedCalc (Medcalc® Software, Mariakerke, Bélgica) de acordo com as necessidades do estudo. As amostras foram divididas sem distinção quanto ao sexo, com distinção quanto ao sexo, e com distinção quanto ao sexo e idade. A comparação dos métodos foi realizada pela diferença de médias da idade dentária com a idade cronológica (ID-IC). A acurácia foi analisada pela Diferença Absoluta (DA). O teste normalidade de Skewness e Kurtosis foi empregado e, dependendo do resultado, os dados foram submetidos ao Test t de Student, ou ao teste de Wilcoxon, para amostras pareadas. Como resultado das comparações sem qualquer distinção quanto ao sexo, a melhor acurácia foi obtida por LLH (DA = 0,97 e ID-IC = 0,58), HKK (DA = 1,42 e ID-IC = -1,35) e MSW (DA = 2,48 e ID-IC = 3,08). Com distinção quanto ao sexo, os valores para o masculino foram: LLH (DA = 0,91 e ID-IC = -0,45), HKK (DA = 1,80 e ID-IC = -1,75) e MSW (DA = 2,74 e ID-IC = 1,17); e para o feminino LLH (DA = 1,01 e ID-IC = -0,67), HKK (DA = 1,17 e ID-IC = -1,09) e MSW (DA = 2,31 e ID-IC = 0,53). Na comparação com distinção entre sexo e idade houve um predomínio respectivamente da técnica de LLH, seguida de HKK e MSW. As equações de regressão aplicadas na mesma amostra apresentaram em média DA = 0,72 e ID-IC = -0,01. Também, algumas fórmulas de regressão múltipla foram construídas a partir dos dados apresentados para as metodologias de LLH e HKK, exceto para MSW que não forneceu dados suficientes para o software criar equações. Ao final, foi possível concluir que é possível a validação das metodologias apresentadas para a população brasileira e que a metodologia que mais se aproximou da população brasileira foi o método de Liliequist e Lundberg com a adaptação de Hägg e Matsson.Age estimation is an important resource in Forensic Dentistry. Among several ways to obtain the age estimation, researchers may do it by analyzing the mineralization stage of permanent teeth. This type of analysis allows that a simple panoramic radiograph to provide relevant data to identify a deceased individual, for example. This study proposes the validation, accuracy analysis and construction of formulas based on the methods Liliequist and Lundberg with the adaptation of Hägg and Matsson (LLH), Haavikko (HKK) and Mornstad et al. (MSW) for the estimation of age by the stage of mineralization of permanent teeth in Brazilian children and adolescents. To achieve the results, panoramic radiographs of Brazilians were selected in a sample containing 1009 radiographs (387 males and 622 females) aged 8-15.99 years. Of these radiographs, it was selected only those that fulfilled all the requirements of the inclusion and exclusion criteria. After applying the methodologies, the results were inserted and worked in the Excel Program, Statistical Package STATA 13.0. (StataCorp LP, College Station, Texas, USA) and MedCalc (Medcalc® Software, Mariakerke, Belgium) according to the needs of the study. The samples were divided without splitting sex, with splitting sex and with splitting sex and age. The comparison of methods was performed by the mean differences between dental age and chronological age (DA-CA). Accuracy was analyzed by Absolute Difference (AD). The Skewness e Kurtosis normality test was employed and the Student t test, or the Wilcoxon test, for paired samples was submitted depending on the results. The results of comparisons informed, without any distinction as to sex, the best accuracy was obtained by LLH (AD = 0.97 and DA-CA = 0.58), HKK (AD = 1.42 and DA-CA = -1.35) and MSW (AD = 2.48 and DA-CA = 3.08). With distinction to sex the values for male were: LLH (AD = 0.91 and DA-CA = -0.45), HKK (AD = 1.80 and DA-CA = -1.75) and MSW (AD = 2.74 and DA-CA = 1.17); and for female: LLH (AD = 1.01 and DA-CA = -0.67), HKK (AD = 1.17 and DA-CA = -1.09) and MSW (AD = 2.31 and DA-CA = 0.53). In the comparison with distinction between sex and age, there was a predominance of the LLH technique, followed by HKK and MSW, respectively. The regression equations applied in the same sample presented mean AD = 0.72 and DA-CA = -0.01. In addition, some multiple regression formulae were constructed from the data presented for LLH and HKK methodologies, except for MSW, which did not provide enough data for the software to create equations. At the end, it was possible to conclude that it is possible to validate the methodologies presented in the Brazilian population and the methodology that most approached the Brazilian population was the Liliequist and Lundberg method with the adaptation of Hägg and Matsson

Changes of the upper lip in orthodontic and orthopedic treatment of angle′s class II malocclusion

Aims: This study aimed to evaluate the changes in upper lips due to incisors retraction in Class II Division 1 patients treated with mandibular protraction, fixed appliances, and without extraction. Materials and Methods: The sample consisted of 64 pre- and post-treatment lateral cephalometric X-rays of 32 patients with 9-12 years old (16 men and 16 women), who presented ANB > 4 o , overjet ≥ 4 mm, treated with Balter′s Bionator and fixed appliances. The average period between initial and final radiographies was 5 years (maximum of 5.5 years and minimum of 4.5 years). Statistical Analysis Used: A Student′s t-test (P < 0.01) evaluated the statistical significance of differences between the mean values obtained for pre- and post-treatment in each variable, for males and females. Linear regression analysis for hard-tissue variables in relation to soft-tissue variables were also made for correlation. Results: The male group presented cervical point with r = 0.40 and incisal point with r = 0.42. Female subjects showed incisor cervical point with r = 0.86 and incisal point r = 0.74. The average Ls retraction was 0.55 mm in 2.43 mm of incisal point movement and 0.34 mm of cervical point. The nasolabial angle showed increase average of 2° for men and 3.9° for women. Conclusion: There is a difference between genders regarding the lip-incisor relation at this age. Males presented thickening of soft tissue and week correlation between the movement of the incisor and soft tissue both cervical and incisal point. In females′ subjects, a strong correlation between the retraction movement and soft tissue, both cervical and incisal point

Accuracy of mandibular measurements of sexual dimorphism using stabilizer equipment

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
