| Abstract | |
The aim of this long-term study was to determine the effecti veness of a cariespreventive program starting during pregnancy on the caries experience of first time mothers and their infants. Eighty-one pregnant women from low social background were selected on the basis of presence of active carious lesions (initial DS 13.98). Initial dental status (DMFS and white spot lesions) and periodontal score (CPITN) were established by clinical examination. Salivary flow rate and buffer capacity were also analyzed. Sixty-four mother-child couples ended the study; thirty-four were in the test group and thirty in the control group. Seventy five per cent of the mothers aged among 14 and 20 years at baseline, and were classified as adolescents. The prophylactic measures, aiming a reduction in caries-risk, were repeated at intervals of 6 months: during pregnancy and 6 and 12 months after delivery. Both groups received educational approach (information about caries etiologic factors, its transmission and prevention, oral hygiene instructions and dietary counseling). Test group also received antimicrobial treatment (professional tooth cleaning and fluoride and iodine topical applications), and restorative care using a glass-ionomer cement. At the children age of 2 years, 33.3 per cent of the infants in the control group were caries-active, compared with 14.7 per cent in the test group. A significant difference in caries prevalence was observed between children with and without visible dental plaque (p = 0.032). The mean ds (including initial caries) was higher in children of control group than in test group (6.3 x 3.2), although not statistically significant. Five children in control group exhibited six or more decayed surfaces compared with no children in this situation on test group. Mothers caries increment among baseline and last recall was assessed and was a significant factor in the caries experience of the children (p = 0.0009). These data support the evidence of an association between caries prevalence in young children and clinical (dental plaque) and maternal factors. (AU) | |
