Results In the groups of children visited regularly only two
developed caries and three had gingivitis (all in group A). In
group E, however, 33 % of children had caries and nine (16%)
had gingivitis. The differences in caries levels and caries risk
factors between study and control groups were statistically
significant (P < 0.001). Mothers of the study groups also showed
an improvement in their own levels of gingivitis, debris and
calculus scores by the second and third examinations (P < 0.001).
