A drilling tool for dental retro-filling preparation comprises an ultrasonic transducer head and one or more elongate drill members for selectively securing to the transducer head. The or each drill member comprises an elongate shaft having a suitable securing mechanism at one end for coupling to the transducer head and a hooked portion at the opposite end comprising the drilling tip which projects at an angle to the remainder of the shaft. The hooked end portion of the shaft is inserted through an appropriate opening in the jawbone until it is located adjacent the tooth root and aligned with the axis of the root, and the transducer head is switched on to cause ultrasonic vibrations in the tip which cut a bore in the tooth root.
