Dentists’ Knowledge and Methods for Restoring Root-canal Treated Teeth in Dubai

Introduction: This study aimed to assess the knowledge of dental practitioners in Dubai regarding concepts in restoring endodontically treated teeth (ETT). Materials and Methods: Registered dentists in the Emirates Medical Association (EMADubai) were sent an online questionnaire of 17 questions about their experience in restoring ETT from January 10 to June 10, 2020. Results: A total of 928 questionnaires were sent. Of these, 468 were completed (50.4% response rate), and 266 were included in the final analysis. Most respondents (77%) placed posts depending on the remaining tooth structure, 14% believed that post placement does not reinforce tooth structure, and 48% replied that reinforcement depends on the remaining structure. The fiber post was preferred both anteriorly (85%) and posteriorly (59%), and composite was the favorite core material both anteriorly (78%) and posteriorly (59%). Resin cement was the most commonly used material for post cementation (49%). Most participants (85%) were familiar with the endocrown and 74% of them used it to restore ETT. Conclusion: Many concepts related to restoring ETT were correctly held by the included sample of dentists. However, the function of the ferrule effect and post placements were often misperceived. This sample of dentists had varying levels of knowledge on the restoration of ETT and this study highlighted the importance of continuing dental education.
