An inherited factor is one of the cause of dental caries. We examined the relationship between SNPs of the enamerin gene and severe dental caries of primary dentition period. The subjects were 120 unrelated individuals of which 75 were severe dental caries patients (dmft10) who visited Matsumoto Dental University hospital, and 45 were healthy volunteers serving as controls. The lingual cells from subjects were harvested with tooth brush and DNAs were extracted. SNPs analysis of the enamerin gene at the position+2452 was carried out a PCR-RFLP method using DNAs and the specific primers. The results suggested that no significant difference was observed between healthy and severe caries subjects. The other candidate genes should be examined.
