Abstract: To evaluate the efficacy of 1% ropivacaine for topical anesthesia in dentistry. Thirty healthy volunteers randomly (blind crossover) received the following treatments: 20 mg of 1% ropivacainegel (ropivacaine-20), 60 mg of 1% ropivacaine gel (ropivacaine-60), 20 mg of the eutectic mixture of local anesthetics 2.5% lidocaine and 2.5% prilocaine (EMLA cream, AstraZeneca; EMLA-20), 60 mg of EMLA (EMLA-60), 20 mg of 20% benzocaine gel (Benzotop, DFL; benzocaine-20), and 60 mg of 20% benzocaine gel (benzocaine-60), applied on the maxillary buccal fold of the right canine at different sessions. Pain was assessed by visual analog scale (VAS) and 11-point box scale (BS-11) after the insertion of 30-gauge needles. Soft tissue anesthesia was measured by pinprick test. Data were analyzed by Friedman and Pearson correlation tests. All the topical anesthetics evaluated showed similar performance in relation to the pain perceived after needle insertion (P >.05), and there were no significant differences among groups considering VAS or BS-11 (P = .177 and P = .179, respectively). The duration of soft tissue anesthesia was not statistically significantly different for ropivacaine-20, EMLA-20, benzocaine-20, ropivacaine-60, EMLA-60, and benzocaine-60, but EMLA-60 showed significantly longer duration than the other agents (P <.05). All topical anesthetics were similar in reducing pain to needle insertion. EMLA-60 promoted longer duration of soft tissue anesthesia
