Purpose:
To explore the use of fissure sealing as a caries preventive method by describing characteristics of children who had received sealants and to study associations between sealing and caries prevalence at 12 years of age.
Methods:
The study included 3075 children examined at 5 and 12 years of age. Data were collected by clinical examination and questionnaire to parents. The questionnaire provided information on child characteristics and oral health behaviour in children at 5 years of age. Data on sealing and caries prevalence were obtained from dental records. Bi- and multivariate logistic regressions were performed. The Regional Committee for Medical Research Ethics approved the study (2.200.54 and 2013/1881).
Results:
Of the children, 12% had received sealants on permanent teeth before 12 years of age. Children with dentin caries at 5 years of age (OR 2.0, CI 1.5-2.7) had a higher probability of having received sealants than children without caries. Having sealants (OR 2.8, CI 2.2-3.6), enamel caries (OR 1.5, CI 1.2-1.9), dentin caries (OR 2.9, CI 2.3-3.6) and using fluoride lozenges less than daily (OR 1.5, CI 1.3-1.8) at 5 years of age were associated with having dentin caries prevalence at 12 years of age.
Conclusion:
Few children had received fissure sealing. Although sealing was used as a caries preventive method in children who had experienced caries in primary teeth, these children continued developing caries in their permanent teeth.

01:15Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
