In order to study the relationship of the patient’s anxiety level from Corah’s Dental Anxiety Scale (DAS) vs different physiological parameters: pre and post-operative blood pressure, and pre and post-operative heart rates, and subsequently, relate the results to the patient’s post-operative anti-inflammatory analgesic need, 185 patients requiring a simple dental extraction were recruited. They filled out the DAS in the waiting room prior to their procedure and once in the examination room, their preoperative blood pressure and heart rate was measured. Once the dental extraction had been completed, their blood pressure and heart rate were measured again. Before leaving the clinic, the patient was given an analgesic form in which they had to indicate whether or not they had required analgesia after the procedure. Diastolic blood pressure (DBP) showed statistically significant differences between pre-operative and post-operative (P = 0.001). DAS was related with pre-operative diastolic blood pressure (pre-DBP) (P = 0.001) and post-operative diastolic blood pressure (post-DBP) as well as pre-operative heart rate (pre-HR) (P = 0.027) and post-operative heart rate (post-HR) (P = 0.013). Patients with high levels of DAS tend to take more Ibuprofen 400 mg (P = 0.038). The different levels of anxiety will determine what type of anti-inflammatory analgesia the patient will take, if necessary.
