Background: The pathogenesis of periodontal disease is a complex process involving interactions among microbial species, host immune response, and environmental factors which results in tissue inflammation and bone destruction. Non surgical therapy, scaling and root planning (SRP) is the most common procedure used to treat gingivitis and periodontitis. Scaling and root planning involves mechanical removal of plaque, calculus (mineralized plaque/tartar); and necrotic cementum respectively, by hand or ultrasonic instruments. Objectives: To evaluate the effect of topical anesthetic EMLA & benzocaine applied intrasulcularly in reducing the pain during scaling and root planning (SRP).
