Abstract
We have conducted an examination on caries risk of primary- and secondary school children (275 children) of Izena village, a remote island village in Okinawa prefecture, using a saliva test (product of Orion Diagnostica Inc.) every year starting from 1997. Oral health instruction and dental treatment is carried on based on the results of this examination. In this report we will show the caries risk-profile of primary- and secondary school children, which was obtained from the examination in 1997. The number of children showed SM score zero, which was an evidence that mutans streptococci in saliva was below the detectable limit, occupied approximately 50%. It showed no relation between plaque score and SM score, and corelation between dietary frequency and LB score was indicated. By conducting this examination on caries risk of school children, we could share the knowledge of caries risk with school staffs and parents. We have realized educational effects on this point.
