Objective To investigate the effects of periodontitis history on intraoperative pain response and postoperative pain duration in patients with oral implants.
Methods A total of 499 patients undergoing oral implant surgery were selected as study subjects. Based on the history of periodontitis as the exposure factor, the patients were divided into exposed group (n=88) and non-exposed group (n=411). The intraoperative painVisual Analogue Scale (VAS) and the postoperative pain duration were compared between the two groups.
Results There was no significant difference in intraoperative pain response between the two groups (P>0.05). The median duration of postoperative pain in the exposed group was three daysInterval of Quartiles(IQR): 2.5 to 5.5, and was two days in the non-exposed group (IQR: 1 to 4). Wilcoxon rank sum test showed that there was significant difference in postoperative pain response time between the two groups (P < 0.01). Multivariate Logistic regression analysis showed that the history of periodontitis was an independent influencing factor for postoperative pain after oral implantation (OR=2.59, 95%CI, 1.58 to 4.23).
Conclusion The pain duration of patients with a history of periodontitis after oral implantation is significantly prolonged, which should be paid more attention to clinically.
