Aim: This study was conducted to compare the frequency of syncope in supine or semi-supine position during local anesthesia in dental surgery. Material and method: One thousand healthy patients presenting for tooth extraction at the Oral and Maxillofacial Surgery Department were selected for the study from February 2019 to February 2020. The patients were divided into two groups. In group A, injection of local anesthesia in the supine position, i.e. while the patient's head and heart were at the same level, in group B, local anesthesia was used in the semi-supine position. Results: There were 1000 patients requiring tooth extraction under local anesthesia with an age range of 15-47years (Mean 28.31± 8.55 years). It was observed that 135 patients (27%) treated in the supine position had pre-syncope symptoms and 245 patients (49%) had pre-syncope symptoms in the semi-supine position. The difference was statistically significant (p <0.0001). No patients were lying supine in this study. Conclusion: It was found that it was easy to prevent fainting if all patients were lying on their backs. Keywords: Dental chair position, Vasodepressor syncope, complications, local anesthesia.
