Forty nine of the Children in case group with a high count alsohad mothers with high count as against only 14 in the control group ( < 0.001. Among 180 mothers, 100 had a high MS count. Among them, 60 (60%) belonged to case group and 40 (40%)to the control group (Among 180 children, 80 of them had a high MS count. Among them, 60 (75%) had ECCand only 20 (25%) were caries free.
