Knowledge, Attitudes, and Practices of Digital Smile Design in Labial Veneer Planning among Dental Practitioners in Southern Saudi Arabia

Aim and objective: This online survey was directed to assess the knowledge, attitudes, and practices (KAP) related to the use of digital smile design (DSD) in labial veneer treatment among dental professionals in Saudi Arabia (SA). Materials and methods:This questionnaire-based study included 180 dental professionals (general dentists and specialists) across SA.A structured, bilingual online questionnaire was distributed via social media channels, and responses were collected.The demographic and professional characteristics were assessed.Dental practitioners' KAP regarding the use of DSD in labial veneer treatment was evaluated.Data were analyzed using descriptive statistics, Chi-square tests, Fisher's exact test, Mann-Whitney U test, and Kruskal-Wallis H test.All statistical tests were two-tailed, and a p-value < 0.05 was considered statistically significant.With no significant difference observed between general dentists and specialists (p = 0.247), a significant association was observed between total knowledge score and years of clinical experience, with the highest scores observed among practitioners with 11-15 years of clinical experience (p = 0.001).Familiarity with DSD, clinical indications, course attendance, and veneer applications differed significantly among specialists compared with general dentists (p < 0.05).Attitudes toward DSD were positive; participants strongly agreed that DSD enhances diagnostic accuracy, patient communication, and digital planning, with significant differences (p < 0.001).The main barriers reported were lack of training (68.3%), increased time requirements (20.6%), and technical complexity (11.1%), with p = 0.001.Conclusion: Despite the positive attitudes and moderate knowledge on DSD in veneer planning, a clinical implementation gap remains.Strengthening practical training through hands-on workshops and curriculum integration is important to facilitate broader and more effective implementation of DSD in labial veneer treatment.Clinical significance: DSD contributes to the accuracy of cosmetic diagnosis, improves treatment planning, and facilitates communication with patients through digital imaging and simulation.These measures can also contribute to improved treatment outcomes and enhanced digital technology quality.
