Effect of proper oral hygiene on gingivitis and dental caries in Swedish schoolchildren.

Lindhe, J.; Axelsson, P.; Tollskog, G.

The present paper reports the effect of a 3-year study of regularly repeated professional toothcleaning on oral hygiene status, gingivitis, and dental caries. At the initiation of the study in 1971, the children were 7-8 years old (Group 1), 10-11 (Group 2) or 13-14 (Group 3). The children were divided into test and control groups. Before the study all the children were examined regarding oral hygiene, state of the gingiva and dental caries. Throughout the 3-year period the controls brushed their teeth with a 0.2 % sodium fluoride solution once a month under supervision. During the first 2 years of the trial all the children of the test groups were given professional oral prophylaxis once every second week during the school terms. During the third year the interval between consecutive prophylactic sessions was prolonged to 4 weeks in Groups 1 and 2 and to 8 weeks in Group 3. The results demonstrated that regularly repeated professional cleaning of the teeth combined with fluoride applications and toothbrushing instructions, over a 3-year period in schoolchildren resulted in the establishment and maintenance of excellent oral hygiene standards. Inflammation of the marginal gingiva almost entirely disappeared, and practically no new carious lesions developed.
