Comparison of a Needle-free Local Anesthetic Technique With Traditional Syringe [ Needle Syringe] Technique for the Restoration of Primary Molars and Permanent Molars

Child Behaviour

The goal of this clinical trial is to compare the effectiveness of needle free system and dental needle system \[Traditional syringe system\] for restoration of Primary and young permanent teeth. The main questions it aims to answer are: 1. To evaluate pain perception for restoration of primary and young permanent tooth with a needle free system in a pediatric population. 2. To evaluate pain perception for restoration of primary and young permanent tooth with needle syringe \[Traditional syringe system\] method in a pediatric population 3. Time required to deliver anesthesia using needle free system vs Needle syringe \[ traditional syringe system\] Participants who enrolled in the study will be anesthetized according to the respective groups i,e needle free system and traditional dental needle system and restoration will be done.

Before the start of the study a written informed consent and ascent was obtained from each parent of the children included in the study stating they accepted the treatment. Ethical clearance will be obtained before the start of the study. Patients reporting to the dental clinics, college of dentistry will be included in the study. Sample size estimation: the sample size was estimated to be twenty-one (21). Twenty percent of the estimated sample size was added to compensate for sampling loss if any, thus the final sample size accounted to a total of twenty-five (25) participants in each group. study design: It was a single blinded randomized controlled trial Randomization: Children will be allocated into one of the following two groups using a simple randomization method with a random number table, employing the sequentially numbered opaque sealed envelopes method of allocation concealment. Group I: All participants in this group were subjected to the traditional needle syringe system. Local infiltration of Scandicaine 2% Speciale \[Mepivacaine Hydrochloride and adrenaline\] was administered using a traditional needle syringe equipped with a 27-gauge needle. Group II: Participants in this group received the needle-free injection system, specifically the INJEX (Injex Pharma AG, Germany) 0.3ml of 2% Scandicaine will be adminsitered. Intervention procedure To avoid any operator-related bias, a single operator will manage the entire anesthesia protocol for all participants in the trial. Employing the tell-show-do technique, all relevant treatment equipment and protocols were introduced and explained to the participants. The injection process was fully described using appropriate euphemisms. Before administering the injection, the treatment area at the injection site was cleansed using a sterile dry gauze, and a small amount of topical anesthetic (Benzocaine 20%, NJ, USA) was applied, remaining in place for at least one minute. Following the application of topical anesthesia, local anesthesia was administered based on the participant's assigned group. After a standard waiting period of three minutes for the onset of anesthesia, dental caries was removed, dycal applied and final restoration with composite was done.
