Background: Heart rate and blood pressure play an important role to determine the cardiac health of the patient during the treatment. Significant alterations in these parameters enable us to take appropriate actions during emergencies and comprehend the potential risks associated with dental procedures. The objective of this study is to determine the changes in the heart rate and blood pressure of the patient before and after dental extraction. Through a thorough evaluation and analysis, researchers endeavour to discern whether there are discernible patterns of alterations in the vital signs in the patient following extraction. Materials and method: A total of 60 patients were selected for the study out of which 34 were males and 26 were females. All the patients were in an age group of 17 till beyond 77 of the age. Prior to the procedure, blood pressure and heart rate were measured. Dental extraction of the tooth was subsequently performed, followed by post-operative measurement of blood pressure and heart rate. Results: Significant difference in post operative pulse was noticed after extraction where there was decrease in post operative pulse. A decrease in post-operative blood pressure was observed, but these variations remained within the normal range. Conclusion: The vital signs exhibited alterations before and after tooth extraction. Thus, it is concluded that various factors such as dental anxiety, stress, local anaesthesia alter the blood pressure and heart rate of a patient post dental extraction.
