Does Preoperative Dental Anxiety Play a Role in Postoperative Pain Perception After Third Molar Surgery?

BACKGROUND: Surgical removal of the impacted third molar is associated with inflammatory morbidities which include swelling, trismus, and pain. Pain is the most common postsurgical morbidity associated with third molar surgery. It remains an important factor in patients' perception of recovery after third molar surgery with dental anxiety reported to exert influence on its threshold. OBJECTIVE: The aim of the study was to determine if preoperative dental anxiety has any significant role on postoperative pain perception after third molar surgery. MATERIALS AND METHODS: This was a cohort study involving sixty consecutive adult patients requiring extraction of impacted mandibular third molars under local anesthesia. Modified Dental Anxiety Scale Questionnaire was administered to each participant in the waiting area before the surgery. The visual analog scale was also given to each participant to be completed once daily at approximately the same time as the surgery time until day 7 after the surgery. Data collected were analyzed using SPSS version 23. RESULTS: Sixty participants who consented to third molar surgery took part in this study. Five participants were lost to follow-up. There were slightly more males (50.9%) than females (49.1%). Nineteen participants in this study had moderate dental anxiety (34.5%) and 6 participants (11%) had severe dental anxiety with more females having moderate-to-severe dental anxiety. The correlation between pain perception at different days and dental anxiety was not significant (P > 0.05). CONCLUSION: Preoperative dental anxiety may not significantly influence pain perception after third molar surgery.
