[Investigations of sensitivity and reliability from Plaque-Index methods].

Abstract

Three independent examiners evaluated the oral and vestibular plaque-index-rate on all teeth at 100 probands. A 7-grade-index computer-transformed into the plaque-values by Quigley and Hein, Silness and Löe and the debris component of Oral-Hygiene-Index was used. From these tested index-methods the index by Quigley and Hein proved to be the better as to sensibility and reliability in comparison to the other two methods.
