Hygienic status of the teeth was assessed after Fyodorov-Volodkina and Green-Vermillion in 500 patients aged 26 to 68 consulted for caries, chronic and acute periodontitis. A good hygienic status of the teeth was observed in 70 subjects: the Fyodorov-Volodkina hygienic index was 1, the Green-Vermillion index O. The Fyodorov-Volodkina index from 1,7 to 5 in 430 patients, depending on the hygienic habits. Patients whose hygienic index was still unsatisfactory despite special training, were subjected to hygienic treatment of teeth with a drill fitted with a modified toothbrush, using water suspension of tooth powder, zink oxide, phosphate cement powder, or tooth paste.
