[Clinical method for objectivization of the effect of oral-hygienic agents on dental plaque and gingiva]

The authors propose a model complex of methods for objectivization of the effect of oral-hygienic agents. Attention is drawn to the selection and preparation of the probands for the clinical experiment, describing also the conditions of the experiment. The most appropriate indices for the evaluation of the effect of the oral-hygienic agents also presented: 1. Doublet plaque-index according to T. Dzemileva and M. Drjankova--enabling the parallel differential evaluation and recording of the incidence and thickness of the dental plaque. 2. Index of Fjodorov and Volodkina--particularly adequate for investigation of the agents for mechanical removal of dental plaque. 3. PMA-index--giving an idea of the therapeutic-prophylactic action of the oral-hygienic agents on gingival status. 4. Supragingival and bilateral probe-imprint--according to the well known method of T. Dzemileva et al. The proper selection of the methods for objectivization of the effect of the oral-higienic agents will guarantee the reliability of the results.
