[Clinical evaluation of fluor protector and glass-ionomer cement used as pit and fissure sealant for preventing pit and fissure caries in children].
OBJECTIVE
To study the clinical effect of the fluor protector and glass-ionomer cement used as pit and fissure sealant for preventing pit and fissure caries in children.


METHODS
622 health permanent teeth in 6-8 years old children were divided into three groups. Children in the experimental group A (n=207,335 teeth) underwent fluor protector every six months, experimental group B(n=205, 327 teeth) with glass-ionomer cement used as pit and fissure sealant and children in the control group(n=210, 354 teeth) underwent no treatment. The incidence of caries were compared among the three groups using SPSS10.0 software package after 3 years.


RESULTS
After 3 years, the incidence of caries in A and B experimental groups were lower than in the control group, the difference was significant (P<0.01), but there were no significant difference between group A and group B (P>0.05).


CONCLUSIONS
Fluor protector and glass-ionomer cement used as pit and fissure sealant also have good clinical effect in preventing caries.
