Title (EN) DRILLING NEEDLE FOR MEDICAL TREATMENT OF ROOT CANALS
(FR) AIGUILLE PERCEUSE POUR LE TRAITEMENT DENTAIRE DES CANAUX RADICULAIRES
Abstract:
(EN) A drilling needle for medical treatment of root canals to a length corresponding to the length of the dental pulp cavity whose depth is preparatively detected by other means. A telescoped member (4) of a grip (2) receiving a bottom portion of the needle (1) is slid by minute grooves in coherent contact with a sleeve (6), so that the length of the needle extending beyond the sleeve (6) can be finely adjusted.
