ABSTRACT:
Dental mirrors are described that by virtue of their design and configuration are self-drying and have the capability of retracting the cheek away from the teeth being examined or worked on by the dentist, all with comfort for and safety to the patient. The mirrors have clips or the like to detachably secure an absorbent roll thereon. The absorbent roll, such as a cotton roll commonly used in the practice of dentistry for absorbing fluids from various regions of the mouth, is preferably positioned and secured in a substantially tangential position relative to a circular or elliptically-shaped mirror. This tangential position in turn may be varied relative to the longitudinal axis of the elongate handle of the dental mirror, since the mirrors can be used for viewing and absorbing fluids from any region of the mouth. Such mirrors enable the dentist to retract the gum from the gumline by means of a soft absorbent roll rather than a hard surface such as the rim of a dental mirror which can and does cause discomfort and even injury to the patient. Concurrently the fluids in the vicinity of the absorbent roll are readily absorbed. Since the roll is in close proximity to the face of the mirror, this absorptive action in turn tends to keep the face of mirror 15 free or at least freer of fluids which would otherwise accumulate thereon. Consequently the ability of the dentist to view the area being examined or worked on is enhanced. Also, with properly designed clips it is a simple matter to replace wet rolls with fresh, dry rolls as needed during the examination or treatment being performed.
