Comparative Study on the Efficacy of Postsurgical Oral Prophylactic Antibiotic Versus Antimicrobial Suture Placement Alone in Preventing Surgical Site Infection After Removal of Impacted Mandibular Third Molar.

Aim: To evaluate the efficacy of postsurgical oral prophylactic antibiotic versus antimicrobial suture placement in preventing infection after removal of an impacted mandibular third molar.

Materials And Methods: This was a prospective, single-blind study including 150 individuals of 18-40 years divided into two groups with 75 patients each. The patients in Group 1 were administered oral amoxicillin tablets 500 mg for 5 days postsurgery with 3-0 polyglactin sutures for closure and in group 2 with (3-0) antimicrobial chlorhexidine diacetate-impregnated polyglactin sutures only.
