Evaluation of anxiety and hemodynamic changes in surgical removal of lower third molar under local anesthesia.

Abstract

Objective: To determine the anxiety and hemodynamic changes in surgical removal of lower third molar under local anesthesia. Study Design: Comparative Cross-sectional study. Setting: Department of Oral and Maxillofacial Surgery, Institute of Dentistry of Liaquat University of Medical Health Sciences, Jamshoro. Period: January 2021 to December 2021. Material & Methods: Three hundred and fourteen patients were selected by non-probability convenience sampling technique. Patient having age between 18 to 50 years with either gender presented with third molar surgical extraction, first experience of tooth extraction and partial bony impaction were included in study. The demographic and clinical parameters like age, gender, level of anxiety and hemodynamic changes were identified. Hemodynamic parameters were recorded on before starting the surgical procedure (T1), after 5 minutes of injecting local anesthesia (T2) and after completion of surgery (T3). Results: Out of 314 patients, male patients were 156 (49.7%) and female patients were 158 (50.3%) with mean age of 31.0 ± 9.2 (18-50). In third molar extraction significant difference was observed for hemodynamic parameters at T1, T2 and T3 intervals. Conclusion: Surgical removal of lower third molar under local anesthesia significantly increases the anxiety, blood pressure and heart rate after injecting local anesthesia.
