Effectiveness of buccal infiltration anaesthesia compared to inferior alveolar nerve block anaesthesia in primary mandibular molar extractions: a randomised controlled study.

Abstract

Aim The current study assessed the efficiency of buccal infiltration (BI) and inferior alveolar nerve block (IANB) during the extraction of deciduous mandibular molars.Subjects and method A total of 112 children aged between 5-8 years with mandibular molar indicated for extraction were divided into two groups at random. The BI group was injected with 4% articaine using BI, while the IANB group was injected with 2% lidocaine using IANB. The effectiveness of both techniques was examined using the Wong-Baker FACES Pain Rating Scale (W-BFPRS); Faces, Legs, Activity, Cry, and Consolability (FLACC) scale; and pulse oximetry.Results Using the W-BFPRS scale, success rates were 83.9% and 75.0% for the BI group and 82.1% and 71.4% for the IANB group during the injection and extraction, respectively, while using the FLACC scale, success rates were 83.9% and 92.9% for the BI group and 78.6% and 89.3% for the IANB group. In terms of pulse rate and oxygen saturation, there was no significant difference between the two groups.Conclusions BI with articaine is as efficient as IANB with lidocaine in the extraction of deciduous mandibular molars.
