title: Accuracy of the Fonseca anamnestic index in the identification of myogenous temporomandibular disorder in female community cases.
abstract: The aim of the present study was to evaluate the accuracy of the Fonseca anamnestic index (FAI) in the identification of myogenous temporomandibular disorder (TMD). Two hundred and three female volunteers participated in this study, 117 with myogenous TMD and 86 without TMD. The Research Diagnostic Criteria for Temporomandibular Disorders were first applied as the gold standard for the diagnosis. The volunteers then answered the 10 items on the FAI, which furnished a score ranging from 0 to 100 points. The receiver operating characteristic (ROC) was used to determine the accuracy of the diagnosis (area under the curve) and the best cutoff point of the tool. Thus, FAI demonstrated a high degree of accuracy for the diagnosis of myogenous TMD (area under the ROC curve of 0.940). The best cutoff point was a score of 47.50. Thus, a score ranging from 0 to 45 points corresponds to the absence of myogenous TMD and scores ranging from 50 to 100 points identifies individuals with the disorder. In conclusion, the high degree of diagnostic accuracy demonstrates that the FAI can be employed for the identification of myogenous TMD in female community cases.
