Validation of a measuring instrument for the perception of oral health in women.

The aim of this study was to estimate the reliability, validity and factorial invariance of the Portuguese version of the Geriatric/General Oral Health Assessment Index (GOHAI) as applied to Brazilian women. A total 701 women over 18 years of age participated in this study. Telephone interviews were conducted. We evaluated the construct-related validity through factorial, convergent and discriminant validity. We carried out a confirmatory factor analysis using the χ2/df, CFI, GFI and RMSEA indexes. The invariance of the model in a second independent sample was estimated by multi-group analysis and internal consistency using Cronbach's alpha coefficient. Items 5 and 9 presented factor weights below the adequate value and were removed. The three-dimensional and unifactorial model presented an adequate fit. We observed strong factorial invariance of the models in two independent samples (three-factor: ρλ = 0.62; pCov = 0.89, one-factor: ρλ = 0.81; pCov = 0.68) and weak factorial invariance between users and nonusers of dental prosthetics (three-factor: ρλ = 0.55; pCov = 0.01, one-factor: ρλ = 0.51; pCov = 0.02). The convergent validity was suboptimal. Internal consistency was adequate. The GOHAI applied to the study sample showed adequate reliability, factorial validity and stability in independent samples and between users and nonusers of dental prosthetics in both the three-dimensional and the unifactorial structures.

Severity of temporomandibular disorders in women: validity and reliability of the Fonseca Anamnestic Index.

The aim of this study was to assess the validity and reliability of the Fonseca Anamnestic Index (IAF), used to assess the severity of temporomandibular disorders, applied to Brazilian women. We used a probabilistic sampling design. The participants were 700 women over 18 years of age, living in the city of Araraquara (SP). The IAF questionnaire was applied by telephone interviews. We conducted Confirmatory Factor Analysis (CFA) using Chi-Square Over Degrees of Freedom (χ2/df), Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), and Root Mean Square Error of Approximation (RMSEA) as goodness of fit indices. We calculated the convergent validity, the average variance extracted (AVE) and the composite reliability (CR). Internal consistency was assessed by Cronbach's alpha coefficient (a).The factorial weights of questions 8 and 10 were below the adequate values. Thus, we refined the original model and these questions were excluded. The resulting factorial model showed appropriate goodness of fit to the sample (c2/df = 3.319, CFI = 0.978, TLI = 0.967, RMSEA = 0.058). The convergent validity (AVE = 0.513, CR = 0.878) and internal consistency (a = 0.745) were adequate. The reduced IAF version showed adequate validity and reliability in a sample of Brazilian women.

Epidemiology of severity of temporomandibular disorders in Brazilian women.

AIMS: To evaluate the severity of temporomandibular disorders (TMD) of women in the municipality of Araraquara (Brazil) as well as the contribution of the perception of oral health, mandibular functional limitation, and sociodemographic variables on the severity of TMD. METHODS: The participants were interviewed by telephone. Information regarding age, marital status, economic level, education, and use and type of dental prostheses was surveyed. To evaluate TMD severity, mandibular functional limitation and perception of oral health, Fonseca's Anamnesic Index (IAF), the Mandibular Function Impairment Questionnaire (MFIQ), and the General Oral Health Assessment Index (GOHAI) were used. To evaluate the contribution of these variables on TMD severity, a structural equation model (SEM) was fitted to the data and assessed by usual goodness-of- fit indices. RESULTS: A total of 701 women with a mean age of 44.36 years (SD = 16.31) participated. According to the IAF, 59.6% (95% confidence interval = 56.0%-63.2%) of the women were classified as having TMD, of which 63.9% presented light, 26.8% moderate, and 9.3% severe TMD. Mandibular functional limitation was low in 91.0% of the women, moderate in 7.1%, and severe in 1.9%. Goodness-of-fit for the structural model was adequate. The predictors explained 43% of the variation in the TMD severity, with significant contributions of the variables dental prostheses (ß = -.008; P = .006), perception of oral health (ß = -.43; P < .001), and mandibular functional limitation (ß = .014; P = 014). CONCLUSION: The severity of TMD among Brazilian women was greater in nonusers of dental prostheses and was also associated with greater mandibular functional limitation and poor perception of oral health.

Dor miofascial crônica e alimentação: uma relação a ser considerada pelo cirurgião-dentista? / Chronic myofascial pain and feeding: a relationship to be considered by the dentist?

Objetivo: comparar o consumo energético, de macronutrientes e fibras por mulheres portadoras de dor miofascial crônica e não portadoras, atendidas durante o ano de 2006, em uma Clínica de Fisioterapia da cidade de Araraquara - SP. Métodos: Os grupos - controle e dor miofascial - foram definidos pelo Critério de Diagnóstico na Pesquisa para Desordens Temporomandibulares - Eixos I e II, sendo compostos por 36 e 37 indivíduos, respectivamente. As participantes foram entrevistadas para o preenchimento do recordatório alimentar de 24 horas de dois dias. A análise da ingestão de energia, macronutrientes e fibras foi realizada com auxílio do programa Virtual Nutri e os grupos foram comparados pelo teste t Student. Para o grupo com dor miofascial, foi realizado estudo de Correlação de Pearson entre os domínios propostos pelo Critério de Diagnóstico na Pesquisa para Desordens Temporomandibulares - intensidade média da dor, depressão, sintomas inespecífcos incluindo itens de dor e limitação da função mandibular - e o consumo de energia, macronutrientes e fibras. O nível de significância adotado foi de 5%. Resultados: Houve diferença estatisticamente significante entre os grupos no consumo de proteínas e lipídios, sendo este menor no grupo de mulheres portadoras de dor miofascial crônica. O consumo energético e de fibras esteve no limite de signifcância. Observou-se correlação não signifcativa entre os domínios do Critério de Diagnóstico na Pesquisa para Desordens Temporomandibulares e o consumo de energia, macronutrientes e fibras. Conclusão: O consumo de proteínas e lipídios foi diferente entre portadores e não portadores de dor miofascial crônica.

Objective: to compare the energetic consumption, of macronutrients and fibers, of chronic myofascial pain carries and non-carries women, attended during the year of 2006, in the Physiotherapy Clinic of Araraquara - SP city. Methods: Control Groups and myofascial pain were defined by the Research Diagnostic Criteria for Temporomandibular Disorders - Axis I and II, being composed by 36 and 37 individuals respectively. The food consumption of the participants were analysed by the 24 hours recall. The analysis of energy, macronutrients and fibers ingestion was realized with the support of the Virtual Nutri program and the groups were compared by the t Student test. For the group of myofascial pain carriers, it was realized the Pearson correlation's study among the domains proposed by the Research Diagnostic Criteria for Temporomandibular Disorders (pain intensity, depression, nonspecifc physical symptoms including items of pain, limitations of jaw functioning) and the consumption of energy, macronutrients and fibers. The level of signifcance was 5%. Results: There was signifcant difference between groups regarding the consumption of proteins and lipids, being observed a lower consumption in the group of carriers of the chronic myofascial pain women. The energetic and fibers consumption was in the limit of the signifcance. It was observed a non-signifcant correlation between the domains of the Research Diagnostic Criteria for Temporomandibular Disorders and the consumption of energy, macronutrients and fibers. Conclusion: The consumption of proteins and lipids were different between carries and non-carries of the chronic myofascial pain.
