Effect of professional toothcleansing every third week on gingivitis and dental caries in children.
A previous paper reported on the 1-year effect on dental caries and gingivitis of biweekly professional toothcleansing. The purpose of this study was to evaluate the influence of a change from 2 to 3 weeks in the interval between the professional toothcleansings during the 2nd year. The DMFS increment during the 2nd year did not differe significantly between the experimental and control groups. The plaque and gingival indices, although  increased during the 2nd year, were still significantly lower in children subjected to the 3-weekly cleansing than in children in the control group.
