Abstract: Dental Injection Pain Reducer Instrument (DIPRI) is a new design being introduced for the first time in the terminology of the dentistry world. The theoretical advantage of DIPRI with vibrating needle is that it should reduce the injection pain and minimize discomfort. Based on the concept of the Gate-Control theory, it is designed for future use in clinical practice. This device is a promising breakthrough in pain management and may deliver solution for clinicians plagued with patient pain phobia. DIPRI is an off-set rotating micro vibration creator that can be easily placed on any standard dental syringe and some disposable syringes. It may also be adapted for conventional intra muscular injections. DIPRI with micro vibration would be effective in reducing the pain confronted with most types of injections as palatal, mandibular block, intraligamental, local infiltration, etc. DIPRI is not only a useful accessory device for conventional patients but also more useful for pediatric patients and those who had a past painful injection. The parts in contact with patient are autoclavable. DIPRI is a registered invention and has an Iranian Official Patent number of 63765.
