title: [Development of gingival inflammations in schoolchildren instructed in proper oral hygiene in a seven-year longitudinal study conducted under clinically controlled conditions and as part of the Preventive Stomatology research project (author's transl)].
abstract: Instruction of six- and seven-year-old children (N = 1167) at the beginning of this longitudinal study was given by a stomatological nurse at weekly intervals and, later, at fortnightly and monthly intervals, respectively. Compared with a group of untreated controls were not only those children who were instructed in proper oral hygiene but children receiving additional doses of amine fluorides as well. During the seven-year period of observation there was noted a distinct improvement in oral hygiene (OHI) as well as a reduction of gingival inflammations (PM index). Whereas additional administration of amine fluorides had no appreciable effect upon both oral hygiene and the condition of health of the gingiva there was a direct relation to the frequency of instructions in oral hygiene at school.
