概要	This study was to investigate the relationship between gingival health and dental caries in elementary school children. The subjects were 474 children aged 7 to 12 years who attended dental check-ups at an elementary school. Children were divided into three groups: a healthier group (H-group) made up of those scoring +2 (excellent) or +1 (good), an equivocal group (E-group) made up of those scoring 0, and a gingival less-healthy group (L-group) made up of those scoring -2 (very poor) or -1 (poor). Overallpercentages for the H-group, E-group and L-groupwere 48.3 %,21.5 -30.2 %, respectively. Thenumber in the L-group increased with increasing age. The mean scores of the DT and DMFT in the H-group were significantly lower than those in the L-group. The results suggest that oral hygiene instruction should be given to children in order to motivate self-care, not only to avoid dentalcaries but also to prevent gingivitis.
