Objective:
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.
Methods:
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.
Results:
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.
Conclusion:
The findings revealed shared misconceptions and gaps in evidence-based TMD knowledge among Lebanese dentists, highlighting the need for targeted educational interventions.
