Molar, Fourth

The goal of this clinical trial is to evaluate whether the topical application of Novox® Drop on surgical wounds after the extraction of lower third molars can have a clinical advantage. The primary objective of the study is to evaluate the possible reduction of masseteric trismus (masticatory muscle spasm - primary outcome) and of post-operative pain and facial edema (swelling - secondary outcomes) after the extraction of impacted third molars compared to those who do not use it (placebo=glycerin-based gel).
