ABSTRACT:
An improved dental mouth mirror has an oval mirrored surface to increase the number of teeth which can be viewed and improve illumination of the mouth and the retraction of oral tissues, but avoids the concomitant obstruction inherent in larger, conventional round dental mouth mirrors. The major axis of the oval mirrored surface is inclined by approximately 75.degree. from the longitudinal axis of the mirror handle to allow adjustment of the field of vision by merely rotating the hand of the operator to change the angle of the mirror handle, thereby obviating the need for axial movement of the mirror handle. The mirrored surface is provided with spaced parallel reference lines for aligning a first reference line with a first tooth surface and comparing a second reference line with a second tooth surface so as to determine parallelism of said first and second tooth surfaces.
