Zusammenfassung: | The reason that children with cleft palates tend to have a greater prevalence of
tooth decay than normal children is unclear. We hypothesized that children with cleft
palates would have increased oral clearance times for foods and, consequently, higher
levels of caries and caries-associated micro-organisms than control children.
Children aged 6–16 yrs, with (n = 81) or without (n = 61) cleft palates, were
studied. Children with cleft palates had DMFT and dmft scores greater (p < 0.01)
than those of the control group. The number of caries-associated organisms was
greater in the saliva of the cleft palate children (all p < 0.001). The oral
hygiene, plaque and gingival index scores were greater (p < 0.0001), oral
clearance was longer (p < 0.01), and levels of sucrose and starch-derived
saccharides higher (p < 0.01) in the cleft palate group. However, salivary
concentrations of organic acids were lower in the children with craniofacial
disorders, probably reflecting the altered physiology of the more mature dental
biofilm. The longer oral clearance times of foods and the consequent generation of
fermentable sugars from starches may contribute to the higher caries prevalence
observed in children with cleft palates. |
