| Research Abstract |
One of the current WHO global goals for oral health in that the DMFT index at l2years of age in the 2000 should be no more than 3. But DMFT index at 12 years of age in Japan shows 3.6 in the 1993, which is yet higher than other developed countries.Since the dental caries of first molars form about 80% of dental caries in permanent teeth under 12 years of age, preventing dental caries of first molar in school children, it must achieve WHO global goal and it must reach developed national level.Moreover selecting high risk subjects and performing intensive prophylaxis on high risk teeth and improving oral hygiene as a whole, we can prevent pandemic caries in schoolchildren effectively.
In this study, we performed on first years pupils and fourth years pupils.At baseline examination we performed individual dietary assessment and we surveyed past illnesses, behavior, dental knowledge, poothbrushing behavior, parents consciousness to dentistry and oral hygiene, the makeup of family from quest

ionnaires, and we examined oral hygiene (P1.I) and dmf and DMF on each tooth surface, and we examined salivary Mautns streptococci count. We analyzed personal caries risk from thesc data.
As a result, strong significant association have been found between caries experience and salivary Mutans streptococci count and oral hygiene state and there was significant association between caries experience and a number of items of questionnaires which are frequency of toothbrushing, parents check of toothbrushing, frequency of intake and the degree of parents interesting to children's dentition.
Taking into consideration this results, we assessed personal caries risk and we performed prophylactic program to improve these risk factors every 3 months on test group. On the control group, we just examined the progress and extent of dental caries every 3 months and we advised dental treatment according to necessity.
As a result, the subjects with reduction of salivary Mutans streptococci count, improvement of oral hygiene and proper frequency of intake in test group were suppressed dental caries occurrence strongly. Test group was significant decrease in dental caries prevalence than control group. We conclude that the prophylactic programwith using fluoride to improve above 3 factor prevent dental caries effectively and we would better put much stress on improving these 3 factor which are salivary Mutans streptococci count, oral hygiene and frequency of intake in the school dental health program.
