Abstract

Introduction

Efficacy of anesthetic supplementation with bupivacaine to control both pain and the number of analgesics ingested after surgery has been proposed; however, no report was found in the literature regarding supplemental use of bupivacaine. Thus, the aim of this study was to evaluate the clinical efficacy of bupivacaine in appeasing postoperative pain, when used as supplemental anesthesia at the end of surgeries to extract mandibular third molars.

Methods

Eighty surgeries were performed in 40 healthy ASA I patients of mandibular bilateral, semi-enclosed, and symmetrical third molars, in a randomized, double-blind, placebo-controlled, and split-mouth clinical trial. Two procedures were performed. In one case, a preoperative anesthetic block was performed with bupivacaine (0.5 %) and epinephrine (1:200,000). Supplementation with the same anesthetic composition was used at the end of the surgery (test group). In the second case (control group), the procedure was identical to that used in the test group, but was supplemented in a randomized double-blind trial with saline (placebo), using the split-mouth method. Postoperative pain (measured with a visual analog scale) was the primary variable studied, and analgesic consumption was the secondary variable. Nonparametric analysis of variance (Wilcoxon test) and a two-tailed test to determine the ratio was used. P value was set at 0.05.

Results

No statistically significant difference (P > 0.05) was found in the variables studied. An adverse effect related to the anesthetic under study was not observed.

Conclusion

There is no appreciable value to the second injection regarding pain and analgesia use, but there was a difference regarding patient acceptance in surgeries of mandibular semi-enclosed and impacted third molars.
