AND PRACTICAL IMPLICATION S Because new caries lesions in the margins of restorations are the main reason for failure and replacement of restorations in primary teeth , it is important to know whether there is a benefit in using GICs in both occlusal and occlusoproximal cavities
BACKGROUND Fluoride released from glass ionomer cements ( GICs ) is capable of preventing caries lesions .
However , the preventive effect in margins of occlusal and occlusoproximal restorations have not been proved .
Prevalence of Approximal Caries in Posterior Teeth in 15-Year-Old Swedish Teenagers in Relation to Their Caries Experience at 3 Years of Age
The aim of the present investigation was to study the prevalence of approximal caries lesions and fillings in posterior teeth at 15 years of age in a prospect ively followed Swedish population ( n = 568 ) , with special reference to their caries experience at the age of 3 years . Only approximal surfaces were recorded , since all children in the Community of Jönköping have had fissure sealing performed on all caries-free permanent molars . At 15 years of age , the mean number of approximal tooth surfaces with initial caries lesions ( Dia ) , manifest caries lesions and fillings ( DmFa ) and total caries experience and fillings ( Di + mFa ) – recorded on bitewing radiographs – was 2.78 , 0.45 and 3.23 , respectively . One third of the adolescents had no approximal caries or fillings ; the Dia constituted 86 % of the Di + mFa . Children with manifest caries at 3 years of age had a higher risk of developing approximal caries in their permanent teeth than caries-free children at the same age ( 41 vs. 17 % ) . Furthermore , children who were caries-free at 3 years of age were more likely to remain caries-free at 15 years of age compared to children with manifest caries ( 37 vs. 17 % ) . All these differences were statistically significant ( p < 0.001 ) . Additionally , early childhood caries experience ( developed before 3 years of age ) had a greater predictive value than late childhood caries experience ( developed between 3 and 6 years of age ) concerning approximal caries at 15 years of age
