Randomized Controlled Trial Clinical TrialEffect of penicillin on postoperative endodontic pain and swelling in symptomatic necrotic teeth.
The purpose of this prospective, randomized, double-blind, placebo-controlled study was to determine the effect of penicillin on postoperative pain and swelling in symptomatic necrotic teeth. Forty-one emergency patients participated and each had a clinical diagnosis of a symptomatic necrotic tooth with associated periapical radiolucency. ⋯ The majority of patients with symptomatic necrotic teeth had significant postoperative pain and require analgesic medication to manage this pain. The administration of penicillin postoperatively did not significantly (p > 0.05) reduce pain, percussion pain, swelling, or the number of analgesic medications taken for symptomatic necrotic teeth with periapical radiolucencies.
