Background: Scaling and root planing (SRP) in periodontitis is considered to be painful and thus requires anesthesia. The present study evaluates the effectiveness of a eutectic mixture of 25 mg/g lignocaine plus 25 mg/g prilocaine and thermosetting agents (EMLA), 20% lignocaine patch, and electronic dental anesthesia (EDA) during SRP. Methods: In a single‐center, randomized, controlled study, 25 subjects with probing depth of 5 mm or more and visual analog scale (VAS) score of ≥30 mm on probing were selected and asked to assess the pain by VAS and verbal rating scale (VRS) during SRP after application of the three agents. Results: The difference between VAS values of patch and EDA ( P = 0.012) and EMLA and EDA ( P = 0.018) is significant, whereas that between patch and EMLA is non‐significant ( P = 1.000). The difference between VRS values of patch and EDA ( P = 0.046) is significant, whereas that between patch and EMLA ( P = 0.655) and EMLA and EDA ( P = 0.180) is non‐significant. According to the VRS scores, 12% of the subjects in the patch group reported no pain, 84% mild pain, and 4% moderate pain. In the EMLA group, 16% reported no pain, 76% mild pain, and 8% moderate pain. In the EDA group, 88% reported mild pain and 12% moderate pain. None reported severe pain. One subject in the patch group had an adverse event of slight redness. Conclusions: The data suggest the topical agents used, 5% EMLA and 20% lignocaine patch, are more effective and comparable. Both are superior in performance to EDA.
