Abstract
Background: When it comes to the diagnosis & prognosis of the teeth involved, endodontic and periodontal diseases provide problems to the dental practitioner. This work was performed to assess knowledge and awareness about Endo-Perio lesion among dental practitioners in western region. Methods: This observational research was conducted in the Saudi Arabia from November 2021 to August 2022. The paper group included 623 aged above 18 years. The outcomes of this study will be analysed using the SPSS program using a pre-tested questionnaire. Results: This research consisted of 623 participants. 49.2% aged between 21-25 ages and 45.4% between 26-30 years old. Males made up 34.3% of the sample and 45.7% were females 55.1% of the participants in our study were familiar with Simon et al classifications of endo-perio lesions. Actinomycetemcomitans was cited by 53% of respondents as the most common bacterium linked to endo-perio lesions, followed by T. denticola, 16.8% S. mutans, and 14% S. aureus. The majority of responders (50%) identified the apical foramen as most direct pathways of communication between pulp and periodontal tissue. Conclusion: In summary, the research showed that Saudi Arabian dental practitioner has a medium degree of endo & perio lesions understanding. Organizing regular training and seminars sessions for dental practitioner working in hospitals and private clinics to strengthen their skills in the detection and management of endo & perio lesion may provide more fruitful outcomes.
