Presence of Temporomandibular Disorders: Outcome Comparisons of Three Screening Instruments
Objectives: This study assessed the prevalence of TMDs using three screening instruments and compared the outcomes of the different TMD screeners. Methods: Subjects, aged 17-24 years, were recruited from a local Polytechnic. The presence of TMDs was determined with the Fonseca Anamnestic Index (FAI), the short-form FAI (SFAI), and the TMD pain screener (TPS). Data were analysed using the Chi-square test and Spearman's correlation (p<0.05). Results: 400 participants (204 females; 196 males) were evaluated. The prevalence of TMDs was 45.8% when subjects were appraised using the FAI. TMD prevalence was 9.5% and 8.5% with the SFAI and TPS respectively. Irrespective of the TMD screener utilized, a female predominance in TMDs was observed. However, significant gender differences were only observed with the FAI (p<0.001) and TPS (p=0.042). The FAI was strongly correlated (rs=0.756) to the SFAI but weakly connected to the TPS (rs=0.395). The correlation between SFAI and TPS was moderate (rs=0.407). Conclusions: A distinct variance in TMD prevalence was observed depending on the TMD screener. As the FAI appeared to over-estimate TMD prevalence, the TPS is preferred for screening painful TMDs and the SFAI for both pain and function-related TMDs.
