Computer-Controlled Dental Anaesthesia Delivery

The device is an electronic system for controlled local-anaesthetic injections. Reviews have compared pain and anxiety with conventional administration.

The device delivers local anaesthetic during dental procedures. The reviewed trials included children and adults and assessed computer-assisted delivery against conventional administration.

Studies measured pain perception, patient behaviour and anxiety around local anaesthesia. These outcomes describe the injection experience rather than the dental procedure itself.

Conventional local-anaesthetic administration is the comparison method in these studies. The question tested is whether controlling the injection electronically changes pain or anxiety scores.

A review of 14 clinical trials found lower pain-perception scores with computer-assisted equipment and reported more cooperative patient behaviour with the device.

Computer-controlled delivery has been studied for pain and anxiety during local anaesthesia. It can reduce pain-perception scores, but studies still assess the injection experience and related behaviour.
