Influence factors of dental anxiety in patients with impacted third molar extractions and its correlation with postoperative pain: a prospective study

ABSTRACT

BACKGROUND: To explore the prevalence of dental anxiety (DA) in patients with third molar extractions and its influence factors and the correlation between DA levels and postoperative pain. MATERIAL AND METHODS: A prospective and descriptive clinical study was performed. All patients who underwent the impacted third molar extraction from October 2017 to February 2019 were enrolled. DA levels were assessed by virtue of the modified dental anxiety scale (MDAS) and pain was assessed with a visual analog scale (VAS). RESULTS: A total of 150 patients were investigated and 136 valid questionnaires were retrieved, with an effective rate of 90.7%. The independent sample t-test and ANOVA results showed that the anxiety level of patients with the third molar extractions was statistically different in gender, teeth extraction experience and self-assessment oral health status. Multiple linear regression analysis with DA as a dependent variable showed that gender and teeth extraction experience were independent factors influencing DA in patients with third molar extractions. Pearson's test showed that there was a significant correlation between DA level in patients and the postoperative pain on the first day (r = 0.542, p = 0.000). CONCLUSIONS: For patients (females, poor oral hygiene and no teeth extraction experience), surgeon should pay more attention to DA of such patients and take measures to reduce the anxiety when removing the third molars. Furthermore, surgeon can recommend oral administration ibuprofen sustained release capsules after surgery
