Title: The effect of pit and fissure sealing on 358 deciduous and permanent teeth
Abstract: AIM:To verify the clinical effect of pit and fissure sealing for children against the caries on the second deciduous molar and the sixth-year molar.METHODS:One hundred and five children were randomly chosen into the clinical observation.The including criterias were the children aged 3-12 whose second deciduous and sixth-year molars had no dental caries or enamel aplasia.In an arch of dentition,the second deciduous and sixth-year molar in one side was the sealing group while isonym tooth in another side was the control group.All cases were then followed up for 1 to 4 years.RESULTS:After the 4th year re-check,of 358 sealed second deciduous molar and sixth-year molars,the complete retention rates of the sealant were 45.07 % and 46.39% respectively;the relative decreases in dental caries were 65.22% and 57.17%(P=0.000)respectively,the actual decreases in dental caries were 21.13% and 12.05%(P=0.000)respectively,and the caries rates in the experimental group were 18.31% and 16.87% respectively,while in the control group 50.70% and 44.58%(P0.05)respectively.CONCLUSION:The pit and fissure sealing technology can prevent effectively from the occurrence of caries in the pit and fissure,and is a good approach to prevent from dental caries.
