Accuracy of the Fonseca Anamnestic Index for identifying pain-related and/or intra-articular Temporomandibular Disorders

ABSTRACT

Objectives: This study established the diagnostic accuracy of the Fonseca Anamnestic Index (FAI) in relation to the Diagnostic Criteria for TMD (DC/TMD) standard.Methods: A total of 866 TMD patients and 57 TMD-free controls were instructed to answer the FAI and DC/TMD Symptom Questionnaire (SQ). Participants were subsequently categorized into no (NT), pain-related (PT), and/or intra-articular (IT) TMDs using the DC/TMD protocolized examination/algorithms. Receiver operating characteristics (ROC) curves, best cut-off points, and accuracy measures were determined.Results:The FAI demonstrated high accuracy for detecting all TMDs, PT, and IT (AUC = 0.96–0.98). The best cut-off points were 22.50 for all TMDs/IT and 27.50 for PT. Sensitivity of the FAI was high (94.23–98.21%), but specificity was moderate (87.72%) for all diagnostic categories.Discussion:The diagnostic accuracy of the FAI for identifying pain-related and intra-articular TMDs was high. FAI scores ≥25 points should be used to screen for TMDs.
