Abstract
Background: Deep Margin Elevation (DME) is a conservative technique for managing subgingival proximal caries, yet its clinical adoption varies among dentists.
Objective: To assess the knowledge, attitudes, and practices regarding DME among Libyan dental practitioners and identify factors influencing its use.
Methods: A cross-sectional survey was conducted among 152 licensed dentists using a 21-item electronic questionnaire. Data on socio-demographics, DME knowledge, attitudes, and clinical practices were collected and analyzed using descriptive statistics and chi-square tests. Associations between formal training, awareness, professional qualifications, and DME adoption were examined (p< 0.05).
Results: Most participants (82.9%) were aware of DME, but only 40.8% had formal training. Positive attitudes were observed, with 63.8% recommending DME as standard practice. Formal training, awareness, and advanced professional qualifications were significantly associated with a higher frequency of DME use and recommendation (p< 0.001).
Conclusion: Education, awareness, and specialization strongly influence DME adoption. Expanding structured training may promote evidence-based management of deep subgingival lesions.
