Abstract
Background: An endo-perio lesion is defined as inflammation on a tooth that is associated with both pulpal and periodontal pathology. Endodonticperiodontic lesions are a clinical difficulty to diagnose and treat properly. According to studies, the awareness and knowledge levels were low in general dentists compared to specialist dentists. This research was done to evaluate knowledge and awareness about Endo-Perio lesion among dentists in Saudi Arabia. Methods: In KSA, an observational cross-sectional questionnaire study was done. The study's population consisted of 773 Saudi dentists. Structured self-administrated questionnaires were applied in this research data. Data was entered on the excel program 2016 and then analyzed using SP SS . Results: There were 773 respondents in the study. 53.7 percent were between the ages of 20 and 25, and 41.4 percent were between the ages of 26 and 30. Males made up 54.3 percent of the sample, while females made up 45.7 percent. Defective restorations, 58.2 percent vertical root fracture, 53 percent dental caries, 67.4 percent plaque and calculus, 26.6 percent malocclusion, and 23.8 percent reported high heat during endodontic therapy were all indicated as risk factors. Conclusion: Dentists and dental interns in Saudi Arabia have a moderate to poor degree of information's and awareness about endo-perio lesions, according to the study. Periodic seminars and workshops for dentists employed in governmental hospitals and private clinics to improve their understanding of EPL might provide better results.
