Brief summary

Dental anesthesia with needle injection cause fear and anxiety in patients about the dental procedures. Therefore, less painful anesthesia alternatives like needleless anesthesia devices to reduce the negative sensation of pain and fear that is always associated with traditional local anesthesia needle injection. The jet injector with INJEX is a needleless injector system that injects the local anesthesia solution into the tissues through a pressure. This research aims to compare the pain score of jet injector with INJEX and traditional local anesthesia needle injection for teeth extraction. Method: 50 patients visiting DOW Ojha Hospital, who needs extraction of bilateral teeth will be included in this study. Data collection approval will be taken from Institutional Review Board (IRB) of DUHS. Complete procedure, study purpose and pain scale will be explained to patients and they will be told that information will be utilized for only research purpose and after that permission will be taken from participants. After taking history, quadrants will be divided; one for local anesthesia by the Jet Injector with INJEX and one for traditional local anesthesia needle injection. After that local anesthesia with Jet Injector INJEX will be given to one side and traditional local anesthesia needle injection will be given to other site for teeth extraction. Then principle investigator will examine the patient pain through the pain scale (Visual Analog Scale) of this study and supervisor will confirm it.

Interventions

DEVICENeedleless jet injector

To assess the pain score through (VAS) scale of needleless jet injector for local anesthesia. Scale has minimum zero number that indicates best outcome and maximum number is ten that indicates worst outcome.

PROCEDUREConventional needle injection

To assess the pain score through (VAS) scale of traditional needle injection for local anesthesia. Scale has minimum zero number that indicates best outcome and maximum number is ten that indicates worst outcome.
