Introduction Pediatric dentists commonly face with the task of giving the local anesthetic to the children who are dreaded of the procedure. There has been a focus worldwide to make any procedure as less as possible for all be it adult or child patient. There are very few studies regarding the efficacy of the cold and vibration application during the injection techniques. Along these lines, the reason for this examination was to assess the efficacy of a local anesthetic procedure without topical application when contrasted to the conventional insertion technique for alleviating pain in children receiving local anesthesia injections and also to compare the pain perception and comfort of patient between conventional and Buzzy system. Materials and methods 150 children between the ages 3-12 was selected. Three groups of 50 each were divided as conventional, alternative and buzzy device groups. Pain response was assessed between the groups as comfort and discomfort. The observations were evaluated using Chi- square analysis. Results There was a significant difference regarding the pain response between the conventional, alternative and the buzzy device technique. (P < 0.000). Significant difference was seen for the mandibular block in the buzzy group. (P < 0.000) No significant difference was observed in the response neither between the maxilla and mandible, nor between boys and girls, between the conventional and alternative techniques in a three groups. Conclusion The alternative and the buzzy device techniques can lower the discomfort in child dental patients and allow the clinician to administer a successful anesthesia.
