Consensus and knowledge gaps on Temporomandibular disorders among Lebanese dentists

This study aimed to assess consensus on various Temporomandibular Disorders (TMD) knowledge statements and examined differences in TMD knowledge among Lebanese licensed dentists based on demographic and professional characteristics. A cross-sectional study was conducted using an electronic self-administered questionnaire comprising 36 TMD knowledge statements derived from existing literature and refined by TMD experts. Consensus was defined as ≥ 70% agreement or disagreement. Associations between knowledge statements and demographic or professional characteristics were analyzed using Chi-square or Fisher’s exact tests for categorical variables and Kruskal–Wallis tests with Dunn’s post-hoc comparisons for continuous variables, with Bonferroni correction for multiple comparisons. A total of 368 dentists participated. Consensus was achieved for 20 statements, of which 15 statements reflected correct, evidence-based knowledge. Significant associations (p < 0.007) were found between several demographic and professional characteristics and response patterns. The findings revealed shared misconceptions and gaps in evidence-based TMD knowledge among Lebanese dentists, highlighting the need for targeted educational interventions.
