Clinical Comparison of Pain Score of Needleless Jet Injector and Conventional Needle Injection for Teeth Extraction Anesthesia (Split Mouth Technique).

Pakistan50 participantsStarted 2025-02-20

Plain-language 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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
