ABSTRACT:
The apparatus and technique enable an instructor, for example, an elementary grade school teacher, to simulate good and band dental hygiene conditions, including the presence of plaque between the teeth and the removal of the same with flossing; the presence of plaque in the periodontal recesses in the tissue around the bases of the teeth and the removal of the same with proper brushing; and the results of failing to brush and/or floss, including the enlargement of the recesss and the ultimate condition in which one or more of the teeth loses its lateral support and becomes wobbly, or is susceptible to being lost altogether. The apparatus and technique also enable the instructor to demonstrate the various skills necessary to proper brushing and flossing, including the skill of "easing" the floss through each of the contact points between pairs of teeth, to avoid injury to the gum tissue below, and the skill of "wrapping" the floss about the contour of each tooth, to remove the widest possible band of plaque. Using the same apparatus that the instructor used in the simulation and demonstration steps, the student can practice and develop his brushing and flossing skills, and he can do so in stages, for ease of understanding.
