Comparative evaluation of pain perception by vibrating needle (VibrajectTM) and conventional syringe anesthesia during various dental procedures in pediatric patients: A short study

Abstract

Background: One of the most important and challenging aspects of behavior management in children during dental treatment is pain control. Fear related behavior has long been recognized as the most difficult aspect of patient management and can be a barrier to good care. Administration of local anesthesia may evoke anxiety not only in the patients but also in the clinicians. Although local anesthesia is most commonly used for pain control in dentistry, researches are going to seek new and better means of managing pain. In this study, we have used a newer vibration device named Vibraject™ to give painless anesthesia. Materials and Methods: 20 children aged between 8 and 14 years, visited the Department of Pedodontics, K.D. Dental College and Hospital, Mathura, for some dental treatment were selected. In the first appointment, local anesthesia using a conventional syringe was administered. The procedure was repeated with Vibraject™ on the opposite side of the same dental arch on the subsequent visit. The child side of the same dewas assessed through visual analog scale (VAS) and faces pain rating scale (FRS) for both the techniques. Various physiological parameters were also assessed and compared between conventional and vibrating injection techniques. Results: A statistically significant difference in VAS and FRS was found between the two techniques whereas when physiological parameters (heart rate, blood pressure, and temperature) were compared at various intervals, the difference was not statistically significant. Conclusion: Vibraject provides less pain while giving local anesthetic injections in comparison to the conventional injection technique in clinical dental procedures.
