Abstract
Surgical removal of third molars is the most common type of surgery in dentistry. It is estimated that more than 10 million third molar extraction surgeries are performed in Brazil each year, even considering that this intervention is mandatory for the Unified Health System (SUS) through the Dental Specialty Center (CEO). There are several protocols for performing the surgery, from the safe amount of anesthetic to the sections of the impacted tooth, in addition to the time variation depending on the degree of difficulty. This study is part of a bioequivalence clinical trial to evaluate the efficacy and safety of postoperative pain control after surgeries to remove impacted lower third molars in 231 participants of both sexes, aged 18 to 40. Among the exclusion criteria, two situations initially proved challenging: performing the surgical procedure in up to 50 minutes and using a maximum of two tubes of the anesthetic mepivacaine hydrochloride 2% with epinephrine 1:100,000. Therefore, the objective of this study was to evaluate, using standard anesthetic techniques, the average number of anesthetic tubes used that produced sufficient analgesia for the removal of impacted mandibular third molars, as well as the average time from intervention to suturing. It can be concluded that in 92.2% of cases, up to two tubes of anesthetic were sufficient for analgesia and completion of the surgical procedure in up to 50 minutes. In 18 participants (7.8%), more than two to four anesthetic tubes were required and the operative time was longer than 60 minutes.
