Overall, 100 patients of both genders were included in the study, with indication of surgical extraction of lower third molar, positioned similarly after being clinically and radiographically checked by X-ray and orthopantomography. Each patient was subjected to both groups in separate sessions: treated with ozone gas and with CHX gel 1%. Data on pain intensity, number of taken analgesics- painkillers, and dry socket were recorded for 48 h and at Day 7
