Cross-cultural adaptation of the Digital Health Literacy Instrument (DHLI) for use on Brazilian adolescents

Abstract The present study aimed to perform the cross-cultural adaptation of the Digital Health Literacy Instrument (DHLI) for native Brazilian Portuguese-speaking adolescents (DHLI-BrA). Cross-cultural adaptation consisted of the following steps: translation, assessment, and adjustments by the expert committee to ensure cultural equivalence; back-translation, and synthesis of back-translations. Cognitive testing was then performed in a pretest with adolescents using cognitive interviews with probing questions on the item's understanding interpretation and response options. Cronbach's alpha coefficient and McDonald's omega were used to estimate the instrument's reliability. Forty-two Brazilian adolescents participated in the study (mean age: 16.0 ± 2.0 years; range: 13 to 19 years). Items that were difficult to understand were adapted to the context of Brazilian adolescents. Cronbach's alpha coefficient and McDonald's omega for the 21 items of the DHLI-BrA were, respectively, 0.79 and 0.80. Cronbach's alpha coefficient for the subscales of the self-report instrument was 0.53-0.79 (range), demonstrating good reliability in the total instrument and moderate reliability in the subscales. This study provides the cross-cultural adapted version of the Digital Health Literacy Instrument (DHLI), which is an instrument for measuring digital Health literacy, for use in Brazilian adolescents (DHLI-BrA).

Resumo O estudo teve o objetivo de adaptar transculturalmente o Digital Health Literacy Instrument (DHLI) para adolescentes nativos do idioma português do Brasil (DHLI-BrA). O estudo de adaptação transcultural consistiu nas seguintes etapas: tradução, avaliação e adequação de equivalência cultural da tradução por comitê de especialistas; retrotradução e síntese das retrotraduções. Foi realizada a testagem cognitiva em pré-teste com adolescentes, utilizando-se entrevistas cognitivas com perguntas de sondagem sobre a compreensão e interpretação dos itens e opções de resposta. O alfa de Cronbach e ômega de McDonald's foram utilizados para estimar a confiabilidade do instrumento. Participaram do pré-teste 42 adolescentes brasileiros com média de idade de 16,0 ± 2,0 (variação de 13-19) anos. Os itens com dificuldade de compreensão foram adaptados ao contexto dos adolescentes brasileiros. O coeficiente alfa de Cronbach e o ômega de McDonald's, para os 21 itens do DHLI-BrA foi respectivamente, 0,79 e 0,80. O coeficiente alfa de Cronbach para as subescalas do instrumento de autorrelato foi de 0,53-0,79 (variação), demonstrando boa confiabilidade no instrumento total e confiabilidade moderada nas subescalas. Este estudo fornece a versão adaptada transculturalmente do Digital Health Literacy Instrument (DHLI), um instrumento de mensuração do letramento digital em saúde, para utilização em adolescentes brasileiros (DHLI-BrA).

Temporomandibular Disorders are Associated with Sociodemographic Factors, Health-Related and Oral Conditions in Adolescents: A Cross-Sectional Study

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 (AU).

Proteção da vitalidade dentino-pulpar em odontopediatria: uma revisão de literatura / Dentin-pulp protection in pediatric dentistry: a review

Dentin and pulp are considered interdependent substrates, known as the dentin-pulp complex. In front of injuries such as caries and trauma, this complex should be protected with restorative materials considered to be protective agents. An ideal material should have properties such as biocompatibility, be antimicrobial, be insoluble in the oral environment, be thermal and electrically insulating, have therapeutic potential, and adequate mechanical properties. As these characteristics are not found in all materials, the dentist must know the advantages and disadvantages of those that are available. This study aimed to perform a critical review of the indirect materials indicated for the protection of dentin-pulp vitality (PDPV) to ensure the success of indirect pulp treatment in primary teeth. A search was carried out in books, theses, dissertations, monographs, printed articles and databases, PubMed, SciELO, and MEDLINE. According to the literature, the success in protecting the dentin-pulp vitality is achieved through an excellent marginal seal, preventing bacterial infiltration in the dentin and controlling the progression of caries. Further clinical studies are needed to evaluate other outcomes after indirect pulp treatment. There isn't a material that has all the desired characteristics for PDPV, and recent studies show that the key to PDPV isn't found in the protective material, but in the restorations marginal sealing, enabling the inactivation of the progression of dental caries.

A dentina e a polpa são consideradas substratos interdependentes, conhecido como complexo dentino-pulpar. Frente a injúrias como cárie e traumatismo, deve-se realizar a proteção desse complexo, baseando-se na inserção de materiais restauradores considerados agentes protetores. Os materiais considerados ideais devem apresentar propriedades como: biocompatibilidade, ser antimicrobiano, ser insolúvel ao meio bucal, ser isolante térmico e elétrico, ter potencial terapêutico e propriedades mecânicas adequadas. Como essas características não são encontradas em todos os materiais, é importante que o cirurgião-dentista conheça as vantagens e as desvantagens daqueles que estão disponíveis comercialmente. O objetivo deste trabalho foi realizar uma revisão crítica da literatura sobre os materiais indicados para proteção indireta da vitalidade dentino-pulpar (PVDP), em dentes decíduos. Para isso, foram pesquisados livros, teses, dissertações, monografias, artigos impressos e das bases de dados, PubMed, SciELO e MEDLINE. De acordo com a literatura, observou-se que a garantia de êxito na proteção da vitalidade dentino-pulpar é alcançada por meio de um ótimo selamento marginal, impedindo a infiltração bacteriana na dentina e controlando a progressão da cárie. São necessários mais estudos clínicos que avaliem outros desfechos após o tratamento indireto da polpa. Não existe um material que possua todas as características desejadas para a PVDP, e estudos recentes demonstram que a chave não se encontra no material protetor, mas sim na vedação marginal das restaurações, propiciando a inativação da progressão da cárie dentária.
