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.

Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
