ABSTRACT:
A method and apparatus are provided for use by dentists in determining the actual length of a root canal based upon a single x-ray picture. The method involves inserting a probe a known distance partially into the root canal before taking the x-ray picture. The picture is then analyzed to compare the visually observed, apparent lengths of the root canal and probe with the known length of the probe. The actual length of the root canal is determined by direct arithmetic proportion based upon the observed apparent lengths. The apparatus facilitates measurement of said observed apparent lengths utilizing manipulating knobs and an illuminated scale resembling a thermometer scale.
