Comparative evaluation of anesthetic efficacy of 4% articaine using buccal infiltration technique and periodontal ligament injection technique for extraction of primary mandibular molars: An In vivo study

Abstract

Introduction: Dental anxiety is patient's psychological response to the dental environment. Local anesthetic injection is the most anxiety-causing procedure for children in dentistry, especially the inferior alveolar nerve block (IANB) which is the most commonly used injection technique for achieving local anesthesia of mandibular molars. The various alternatives explored for IANB are intra-ligamentary technique/periodontal injection technique and buccal infiltration. Aim: The aim of this study was to compare the effectiveness of articaine hydrochloride 4% with adrenaline 1:100,000 for the extraction of mandibular primary molar teeth using buccal infiltration injection and intraligamentary injection. Materials and Methods: The present study was conducted on 30 children in the age group of 5–10 years requiring bilateral extraction of primary mandibular molars. The patients were randomly selected and divided into two groups. Group 1 received anesthesia using buccal infiltration injection technique and Group 2 received anesthesia using intraligamentary injection both containing 4% articaine with 1:1,00,000 adrenaline. Results: The success rate of buccal infiltration and intraligamentary injection using 4% articaine with mean sound, eye, and motor scores (± standard deviation) was found to be statistically nonsignificant, i.e., 3.07 for buccal infiltration and 2.97 for intraligamentary injection technique with P = 0.835 (P > 0.05). Conclusion: There is no significant difference between buccal infiltration technique and intraligamentary injection technique for the extraction of primary mandibular molars using 4% articaine with 1:1,00,000 adrenaline.
