Consensus and knowledge gaps on Temporomandibular disorders among Lebanese dentists

Area of Science:

• Dental Science
• Oral Health
• Clinical Dentistry

Background:

• Temporomandibular Disorders (TMD) represent a complex group of conditions affecting the temporomandibular joint and masticatory muscles.
• Accurate knowledge of TMD is crucial for effective diagnosis and management by dental professionals.
• Existing literature suggests potential knowledge gaps among dentists regarding evidence-based TMD practices.

Purpose of the Study:

• To evaluate the level of consensus on Temporomandibular Disorders (TMD) knowledge statements among Lebanese dentists.
• To identify disparities in TMD knowledge based on dentists' demographic and professional attributes.
• To pinpoint specific areas of misconception or insufficient knowledge in TMD among the surveyed population.

Main Methods:

• A cross-sectional study design was employed, utilizing an electronic self-administered questionnaire.
• The questionnaire included 36 TMD knowledge statements, developed from existing literature and expert consensus.
• Statistical analyses included Chi-square/Fisher's exact tests and Kruskal-Wallis tests with post-hoc comparisons to assess associations between knowledge and characteristics.

Main Results:

• A total of 368 Lebanese dentists participated in the study.
• Consensus was reached on 20 statements, with 15 reflecting correct, evidence-based knowledge.
• Significant associations (p < 0.007) were observed between various demographic/professional factors and dentists' TMD knowledge response patterns.

Conclusions:

• The study identified prevalent misconceptions and gaps in evidence-based Temporomandibular Disorders knowledge among Lebanese dentists.
• These findings underscore a critical need for developing and implementing targeted educational initiatives.
• Improving TMD knowledge is essential for enhancing the quality of care provided to patients with these conditions.
