Can signs and symptoms of TMD be used in prediction of orthodontic treatment need?

Aim: To explore whether sign and symptoms of temporomandibular dysfunction (TMD) can be used in prediction of orthodontic treatment need in children and adolescents. Subjects and Methods: One thousand five hundred and ninety-seven subjects aged 11 - 19 years, without previous orthodontic history, from sixteen randomly selected public schools in Zagreb, Croatia, were examined. Orthodontic treatment need was assessed by using the Dental Aesthetic Index (DAI) and Index of Complexity, Outcome and Need (ICON). Data on TMD signs / symptoms and parafunctional behaviour were obtained by means of questionnaire and clinical examination, respectively. Multiple linear regression was used for analysis. Results: Twenty-two percent of children and young adolescents had one or more TMD signs / symptoms, ranging from 17% in age of 11 years up to 24% in age of 19. There was significant but poor correlation between TMD signs / symptoms and orthodontic treatment need, and regression models accounted for less than 6% of variability (p<0.001). When controlling for age and gender only altered joint function and tooth wear showed significant but weak positive correlation with orthodontic treatment need assessed by DAI (p<0.05). In ICON model, when controlling for age and gender, maximal mouth opening, deviation on opening and tooth wear correlated with orthodontic treatment need (p<0.05). Conclusion: TMD signs and symptoms are poor predictors of orthodontic treatment need in children and adolescents.
