Comparative study of oral health status between Scottish and Japanese schoolchildren aged6–11 years

This study was carried out to examine and compare the differences in oral health status between Scottish (Fife) and Japanese (Motoyoshi) primary schoolchildren, and also to analyse some factors concerned with the differences found. It was observed that caries experience is higher in Motoyoshi than in Fife, despite Fife schoolchildren having poorer oral cleanliness and consuming snacks more frequently. However, Fife children had more fissure sealants and brushed their teeth more frequently with fluoridated dentifrice than did Motoyoshi children. The sugar content of snacks consumed by Motoyoshi children was higher than that of the Scots. Gingivitis (PMA positive rate) was higher in Fife than in Motoyoshi, and it was also noted that Fife children were less independent than Motoyoshi children in their daily behaviour.
