A newly-develqped, multiple-function dental syringe, designed to improve the efficiency of the dental team in performing restorative operations, was evaluated in mechanical tests, mock clinical trials, and field tests with live patients. Field tests indicated the new device to be superior to the conventional equipment configuration of separate instruments generally used by dental assistants in terms of the number of hand movements required, total cutting time, and operator preference. Suggestions for redesign are presented together with a revised evaluation procedure for future studies.
