Few children receive fissure sealants, a caries preventive method. Even when used, children with prior caries continued to develop permanent tooth decay.
Area of Science:
- Pediatric Dentistry
- Caries Prevention
- Dental Sealants
Background:
- Dental caries remains a significant public health issue in children.
- Fissure sealing is a recognized method for preventing pit and fissure caries.
- Understanding sealant uptake and effectiveness is crucial for optimizing preventive strategies.
Purpose of the Study:
- To investigate the characteristics of children receiving fissure sealants.
- To assess the association between fissure sealing and caries prevalence at age 12.
- To evaluate sealant use as a caries preventive method in children.
Main Methods:
- A longitudinal study involving 3075 children examined at ages 5 and 12.
- Data collected via clinical examination, parental questionnaires, and dental records.
- Bi- and multivariate logistic regression analyses were employed.
Main Results:
- Only 12% of children received sealants on permanent teeth before age 12.
- Children with dentin caries at age 5 were more likely to have received sealants.
- Sealant use, prior caries, and reduced fluoride lozenge use were associated with caries prevalence at age 12.
Conclusions:
- Fissure sealing uptake in children was low.
- Sealants were primarily used in children with existing caries, but did not prevent future decay.
- Further research is needed to improve the effectiveness of caries prevention strategies.

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...
