Comparison of Computer-Controlled Intraligamentary Local Anesthesia and Conventional Inferior Alveolar Nerve Block in Primary Molar Extractions: A Randomized Clinical Trial

Abstract

Highlights What are the main findings? The findings suggest that interligamentary anesthesia using a Computer-Controlled Local Anesthesia Delivery System provides less painful injections compared to the conventional inferior alveolar nerve block. It has demonstrated effectiveness as a viable alternative for the extraction of mandibular primary molars. What are the implications of the main findings? By promoting the use of CCLADS, pediatric dentists can address the negative behaviors children may exhibit towards dental treatment, fostering a more positive dental environment and encouraging future visits. The findings provide valuable clinical evidence supporting the adoption of advanced anesthesia techniques, enabling pediatric dentists to make informed decisions that enhance care quality and patient satisfaction. Abstract Background/Objectives: The study evaluates pain perception in children aged 5–9 during dental extractions, comparing intraligamentary anesthesia (ILA) delivered with a Computer-Controlled Local Anesthetic Delivery System (CCLADS) vs. the traditional inferior alveolar nerve block (IANB). Methods: A randomized clinical trial with 60 healthy, cooperative children measured pain both subjectively using the Wong–Baker Faces Pain Rating Scale (WBFPRS) and objectively using the Sound-Eye-Motor (SEM) scale. Results: Results showed significantly lower mean pain scores with CCLADS during anesthesia administration: WBFPRS was 2.0 ± 2.2 vs. 6.9 ± 2.6 for IANB (p < 0.001). Objective SEM scores during anesthesia delivery were also lower with CCLADS (3.7 ± 0.8) compared with IANB (5.7 ± 1.2) (p < 0.001). During the extraction itself, SEM scores did not differ significantly between groups. Conclusions: The authors conclude that ILA via CCLADS reduces discomfort during anesthesia without compromising anesthetic effectiveness.
