RESUMO
OBJECTIVES: To evaluate Knowledge, Attitude, and Practice (KAP) regarding deep margin elevation (DME) among dental practitioners in Riyadh city. MATERIALS AND METHODOLOGY: A cross-sectional study that comprised a total number of 535 dental practitioners: 255 (47.7%) were males and 280 (52.3%) females. A self-constructed 21 close-ended self-administered questionnaire was utilized in the study. The data were entered and analyzed by Chi-square test and descriptive analysis using Statistical Package for the Social Sciences (SPSS) software. RESULTS: Although the majority of the respondents have heard about DME, only 30.4% have utilized this technique in their clinical practice by having general practitioners and specialists utilize this technique more often than consultants. Among the participants, 65.4% of them have agreed that adhesion by bonding to deep cervical dentin is predictable and related to the success of the final restoration. CONCLUSION: The knowledge level of DME among the study participants was adequate. The findings of this study revealed that the total number of dentists who utilize the technique in restoring large subgingival defects of posterior teeth with proximal caries is very minimal. Thus, it is recommended that dental practitioners have this technique introduced in their dental clinics as an alternative to surgical crown lengthening. Although years of experience and dentist rank may influence the clinical decision, in-depth factorial analysis with a greater sample size is necessary.
