Randomized Controlled TrialA preliminary study of intra-pocket topical versus injected anaesthetic for scaling and root planing.
Compare the efficacy of topical benzocaine gel to injected lidocaine during scaling and root planing. ⋯ Intra-pocket benzocaine gel is less effective than injected lidocaine in controlling pain during scaling and planing. Anaesthetic preference was related to the level of pain experienced during treatment with the topical. Larger studies are needed to confirm these findings.
