Abstract: Introduction: Previous investigation has shown that a combination labial plus lingual infiltration of 3.6 mL of 4% articaine with 1:100,000 epinephrine in the anterior mandible is superior to a labial infiltration of 1.8 mL of the same solution. However, it is not known whether the total volume or the location of deposition had the greatest effect. The purpose of this study was to determine the anesthetic efficacy of a labial plus lingual infiltration of 3.6 mL of 4% articaine versus two labial infiltrations of the same volume/solution in mandibular anterior teeth. Methods: One hundred subjects randomly received two sets of injections consisting of labial and lingual infiltration injections of 1.8 mL (3.6 mL total) of 4% articaine with 1:100,000 epinephrine and two labial infiltration injections of the same volume/solution given beside a mandibular lateral incisor in two separate appointments, in a crossover design. The subjects rated pain of injection and electric pulp testing was used to determine anesthetic success. The data was analyzed statistically. Results: In mandibular lateral incisors, the buccal and lingual combination exhibited a significantly higher anesthetic success rate as compared to the two buccal injections group. The pain ratings were similar for both injection types. Conclusions: In conclusion, a combination labial plus lingual infiltration of 4% articaine with 1:100,000 epinephrine for anterior teeth was not more painful than two buccal infiltrations of articaine and the labial plus lingual infiltrations significantly increased the pulpal anesthetic success as compared to two buccal infiltrations.
