title: The effectiveness of infiltration anesthesia in the mandibular primary molar region.
abstract: The purposes of the present study were to determine the effectiveness of infiltration anesthesia in the mandibular primary molars, and how patient age, tooth location, and anesthetic type relate to the quality of anesthesia. Data were derived from 66 subjects, 42-72 months old, requiring restorative treatment in mandibular primary molars. Infiltration anesthesia was provided with mepivacaine hydrochloride 2%, prilocaine hydrochloride 4%, and articaine hydrochloride 4%. After 10 min, probing, rubber dam placement, and drilling were initiated. Procedures were videotaped and ratings of comfort and behaviors were made using the SEM scale and the Frankl Behavioral Scale. The conclusions were: 1) sixty-five per cent of the subjects experienced little or no pain; 2) children who demonstrated little or no pain during injection were likely to be comfortable during successive procedures; 3) there was a high relationship between children behaving cooperatively and comfort during procedures; and 4) the quality of anesthesia was not significantly related to tooth location, age, or type of anesthetic agent.
