Comparison of pain perception during administration of local anesthesia with jet injector and conventional injection technique using Wong- Baker scale in 6-12 years old children – a randomized controlled trial.

Needle-relatedpain (NRP)/ Blenophobia occurs most frequently during anesthesia in dentistry.In children, the pain from NRPs can produce an emotional and negative cognitiveresponse towards the procedure. Pain haslong been associated with dentistry and has anunusual relation and is the main reason that leads the patient to seek dental treatment.In addition, dental fear and anxiety are the main causes that may leadpatients to bypass dental appointments. Fear-related behaviors have long beenrecognized as the most serious aspect of patient management and can be animpediment to dental care. For invasiveprocedures, pain control is achieved typically by means of injection of localanesthesia. Although this method is highly effective, it is also the dentalprocedure that is most often associated with anxiety and negative responses.For some patients, the injection itself is painful, and thus the procedure thatis designed to reduce pain may itself result in fear and procrastination.In addition,patients often experience more fear at the sight of a needle during theadministration of local anesthetic than from the treatment itself. Therefore,dentists have attempted to minimize the intensity of NRP associated with anydental problem. The objective fear of thechild during administration of localanesthesia ranges from sight of the needle to the pain that might be associatedwith needle injection, which increases the anxiety of the patient resulting infear of receiving local anesthesia in the future. Thus,there is a need for attempting use of  several methods to minimize pain duringadministering local anesthesia. Jet-injectorare needle-free systems that work with the principle of applying anestheticsolution with pressure to penetrate the tissues with spring-loaded devices, ina manner reinforced with pressurized air or gas. To the best of our knowledge, limitedliterature is available on the pain perception of the jet injectors onpediatric population. In this study, we aimed to compare the pain perception ofjet injector method and conventional injection method in a pediatric populationof age 6-12 years.

Primary Objectives: Tocompare the effect of the jet injection and conventional injection method onpain perception in children 6-12 years of age using Wong- Baker scale.

Methodology: Childrencoming in the department of pedodontics and preventive dentistry will beincluded in study and requiring administration of local anesthesia  on both sides of maxilla will be included instudy for various procedures. Basedon inclusion criteria, 50 children of age group 6- 12 years will be selectedfor study. Both the genders will have equal opportunity toparticipate in the study.Each child will be assigned for both the jet injector and conventionalinjection technique. Method to be administered first will be decidedalternately and the side determination will be done by flip the coin technique.
