Abstract
This report describes an oral hygiene promotion program and its results in Higashiyuri-machi in Akita Prefecture, where there was a serious incidence of caries in infants in the 1980 s. This research was conducted over a ten year period with emphasis on the development of better eating habits and improved dental hygiene. Participants were advised as follows : 1. Eat three meals a day 2. Restrict snacks and beverages containing sugar 3. Have teeth brushed at bedtime by caregiver 4. Seal of infant tooth occlusal surface if possible Results in 1992 showed a great reduction in the incidence of caries in three-year-old infants. In 1993, the average number of dmf teeth per three-year-old was also considerably improved. Comparatively, in the 1980 s the incidence of caries for three-year-old was over 80%, while in 1998 it was under 40%. For the same group, the average number of dmf teeth per person was 6.1 in the 1980 s, and 2.2 in 1998. The following factors might have helped achieve these improvements : 1. Rules were made to control the frequency, size and quality of snacks 2. The intake of milk, water and tea was increased to replace other beverages 3. Teeth were brushed more frequently by caregivers. The results among sixth graders in primary schools showed similar improvements in 1998 when following the same routines : there was a decrease in the incidence of caries and a reduction in the number of DMF teeth per individual. Indications are that such a program, based on an understanding of regional characteristics, can improve the dental health of those targeted. Oral hygienists must take a leading role in developing these routines. Dentists can plan programs based on regional health characteristics, and undertake administrative roles as well.
