MD COOL is a vibrating dental local anaesthesia attachment based on the concept of the gate-control theory. It is attached to the syringe body, high frequency needle vibrations block injection pain based on the Gate Control Theory. MDCOOL blocks pain from injections based on the Gate Control Theory. The battery operated motor attaches to a conventional syringe causing the needle to vibrate. The high frequency vibration of the needle blocks the transmission of pain feelings. MDCOOL is a cost effective device that snaps right on to your existing syringe. MDCOOL uses very simple and cost effective, proven technology to improve your injections whether giving intraligamentals, palatals or blocks.
 

MD COOL is a small device that snaps onto the needle syringe, before inserting the needle, simply turn the MD COOL device and it start the vibrating the needle at a high frequency. Patients can hear the vibration, but because needle is vibrating, these vibrations are picked up first by your nerves, and thus do not transmit any feeling of pain.

MD COOL allows dentist to administer painless injections to the patients.
