[Plaque indices].
The objective quantitative evaluation of the extent of plaques is necessary for epidemiologic studies and for the estimation of the effects of various cleaning methods and agents. Numerous indices have been elaborated for this purpose. Relation planimetry is used for the detection and exact evaluation of small differences. The surfaces are measured with a compensating planimeter, the slides to be evaluated being projected on a white sheet by means of a microfilm reader. In this way, the plaque covered surfaces are determined as percentages of the total surfaces.
