During dental procedures mirrors used can become soiled with debris, obstructing visibility. A disposable two piece push wiper system was developed to remove this debris while inside the patient’s mouth. A rod with a wiper at the end slides inside of a case that attaches to the dental mirror handle. Pushing the rod deflects the wiper up the mirror surface and cleans off debris in the process. The wiper head contains a slit for a rubber insert, the means by which debris is removed. Tests were conducted using 3 types of debris: toothpaste, simulated blood, and solid fragments. Debris was added to the mirror surface, the wiper was actuated, and visibility was measured. These tests indicate that this attachment can consistently clean 80% or more of the mirror in 3 activations.
