Abstract

Background: The purpose of the study was to compare the efficacy of the use of 0.2% chlorhexidine irrigation and the oral antibiotics for the prevention of postoperative complication like pain, trismus, swelling and infection after the surgical extraction of IMTM.

Material and methods: A randomised, double blinded clinical trial was planned with two equal groups. Patients were randomly divided into two groups using computer-generated codes with an allocation ratio of 1:1. Group I (Control): Standard preoperative and postoperative systemic oral antibiotics and Group II (Study): No systemic antibiotics and Chlorhexidine irrigation local delivery. The primary outcomes evaluated were postoperative pain, mouth opening, swelling and infection. The secondary outcome variables were the number of analgesics and antibiotics taken by the patient in the postoperative period, the satisfaction of the patient and adverse events, were followed up regulary for 7 days postoperatively.

Results: A total of 84 patients, divided into two equal groups participated in the study. In intergroup comparison of swelling, the difference was non-significant on postoperative day (POD) 1 and 7, except for POD 3, where it showed significantly lower results in the antibiotic group (p = 0.012). However, there was no significant difference in pain found between both groups at any of the postoperative time points, and the study group had a lesser need for rescue analgesics than the control group. A statistically significant difference in incidence of dry socket was observed (p = 0.03) and gastrointestinal adverse symptoms, but it showed insignificant results for wound dehiscence and pus discharge. Also, patient satisfaction was higher in the study group.

Conclusions: both antibiotics and localised delivery demonstrated comparable results in terms of swelling, pain and trismus. However, with lesser adverse events, the localised chlorhexidine delivery with curved tips outperformed the antibiotic group.
