Dental drill

Abstract

The invention refers to a dental drill that can prevent the deterioration of the visual field of the surgical field. An anti-reflective coating 100 is formed on the upper and lateral surfaces of the head 241 of the cap 24 near the root canal of the tooth that the operator notices, and further on the outer surface of the second cylindrical part 12 (see Fig. 3). Therefore, the light reflection of dental lighting instruments equipped with an anti-reflective coating is suppressed, and the degradation of the surgical field visibility can be avoided. In addition, the visibility of stains such as protein deposits on the cap 24 and the second cylindrical part 12 is improved, and their cleaning is facilitated.
