Combination dental mirror and measurement gauge

摘要

A multi-purpose dental tool integrating a dental measuring gauge into the elongated shaft of a conventional dental instrument (i.e. dental mirror). The elongated shaft of the dental mirror is formed with a channel or groove that extends from a flat end (opposite the dental mirror) approximately 30 mm lengthwise along the shaft. The groove is for receiving a root canal file having a stopper along its body indicating depth of penetration into a root canal until the apical foramen. The file is inserted into the groove until the stopper abuts the flat end of the shaft. The groove is further marked with measuring lines for accurately measuring the length of the file within the groove.
