“…Lignocaine, which is used for infiltration anesthesia is an amide anesthetic. Kishimoto et al [ 34 ] compared the effects of lignocaine and benzocaine delivered through transmucosal patches based on trigeminal somatosensory evoked potentials. They observed that an amide anesthetic like lignocaine had similar efficacy to benzocaine when used as a topical anesthetic and concluded that 2% lidocaine with epinephrine used as a topical anesthetic in an adhesive patch was as potent as 20% benzocaine.…”

Background: Placement of full-coverage restorations such as stainless steel crowns (SSCs) for pulpectomy treated primary molars is essential for successful outcomes. The tooth preparation process for SSCs can cause discomfort to gingival tissues since the crown should be seated 1 mm subgingivally. The purpose of this prospective trial was to compare the effectiveness of subgingival and transmucosal application of topical anesthetics on dental pain during SSC tooth preparation among 6-to 8-year-old children. Methods: A consecutive sample of 27 children, aged 6-8 years, who required an SSC after pulp therapy in primary molars were randomly divided into three groups. Group A received infiltration anesthesia before tooth preparation for SSC placement, whereas in Group B and C, only topical anesthesia was applied subgingivally and transmucosally. Wong-Bakers Faces pain rating scale (WBFPS) scores were recorded after tooth preparation. Faces, Legs, Activity, Cry and Consolability (FLACC) scores were evaluated by two blinded and calibrated investigators through video recordings of the patient during tooth preparation. Data were tabulated, and inter-group comparisons were performed using the Kruskal-Wallis and analysis of variance tests. Results: Out of the 27 participants, 48% were boys and 52% were girls, with an overall mean age of 6.83 years. Group A showed the least pain scores according to both the scales, followed by Group B and Group C. The pain intensity was statistically significant on both the pain scales with P = 0.003 for FLACC and P < 0.001 for WBFPS. Conclusion: Subgingival application of topical anesthesia reduced pain to a certain extent but not as effectively as infiltration anesthesia during SSC tooth preparation in primary molars. Transmucosal application of topical anesthesia did not reduce discomfort when compared to the other two interventions.

“…It has been found that the 10% dose of lidocaine gives the same result as the 20% dose with mepivacaine [24] . Several authors have reported in the literature that, within the lidocaine patch presentation, the 5% presentation can significantly reduce the pain of needle injection more than the gel in children [25,26,27,28] .…”

Introduction: Topical anesthetics are of great interest in pediatric dentistry because they act on the peripheral nerves reducing the sensation of pain when applying local anesthetics. Objective: To analyze the most recent literature on topical anesthetics: benzocaine, lidocaine, eutectic mixture of local anesthetics (EMLA), generalities, doses and presentations, uses and adverse effects. Methodology: Articles on topical anesthetics in pediatric dentistry were analyzed in the databases PubMed, SCOPUS and Google academic with emphasis on the last 5 years. This was done with the words: "dental anesthetic", "benzocaine", "lidocaine", "Pediatric dentistry", "EMLA". Results: It has been found that 20% benzocaine is the most used anesthetic, its main use is before local anesthetic puncture, it has a pleasant taste, however, high rates of allergies have been reported. As for lidocaine, it is effective when applied in 1 minute, its 10% aerosol presentation has presented the best results, its toxicity levels are low but it has an unpleasant taste. EMLA is a mixture of lidocaine 2.5% and prilocaine 2.5%, it is used before puncture, when placing orthodontic separators and in small biopsies, its application time is 2 to 10 minutes and it can cause numbness in unwanted areas. Conclusion: Currently there is no topical formulation that completely eliminates the pain caused by needle puncture, therefore, products with greater efficacy are awaited.
