Clinical assessment of two fissure sealant techniques in children’s dental caries prevention

To compare clinical effects of children’s dental caries prevention with enameloplasty sealant technique (EST) and traditional fissure sealant technique.

50 children with healthy teeth were selected randomly ,from the age of 6 to 8.5 years old and to tally 82 pairs of first molars were included (different sides of the same jaw was considered as a pair). In a self-control study, the right side was treated through enameloplasty sealant technique (group A), the left side was cured with traditional fissure sealant technique (group B). According to follow-up visit after 1 year, 2 years and 3 years, the results of two sealant techniques were evaluated.

The incidence of group A was 2.5%, 3.9%, 5.7% from 1-3 years, whereas the incidence of group B was 2.5%, 10.4% and 15.7%. No significant statistic difference was shown in the first year. However significant statistic difference was illustrated in the second and third year (P ＜ 0.05).

For preventing dental caries in children, enameloplasty sealant technique showed a better long-term clinical effect.
