In Japan, medical expenses insurance is on a piece-rate basis,
national dental expenses/national income is 0.7%; ¥ 2,538 billion,
04. The dental expenses insurance was included slightly
preventive care. Unfortunately, certain dentists and dental
hygienists give priority professional care in clinic and self care in
home over public care.

Other fluoride uses at present in Japan:
1) Community water fluoridation;
none except some natural areas (06)
2) Professional topical fluoride application in 1-14 years old;
59% (05 From Minister of Health, Labor and Welfare)
3) Fluoridated dentifrice in market share;
88% (05 From Lion Foundation of Dental Health)
4) Number of children in FMR at home in 4-14 years old
(estimated data); 347,000
(02 From Ando, et al)
5) FMR agents as over the counter drug (OTC);
none for sale at present (30. Nov. 06)
The goals to 2010 in Japan by NPO-JPUF:
1) Community water fluoridation;
realizing in some areas
2) S-FMR; Number of children will be increased to
1,000,000
3) Fluoridated dentifrice in market share;
more than 90%
(88% in 05) ⇨ realized ?!
4) Professional topical fluoride application;
more than 60%
(59% in 05) ⇨ realized ?!
Purpose
1)
Follow up the spreading conditions of the schoolbased fluoride mouth rinsing program (S-FMR)
since 1970.
2)
Estimate the total number of schools and children
participating in the S-FMR for proposition regard-
ing final assessment of Healthy Japan 21 in 2010.
3)
Set up the next goal, and promote the fluoride
uses throughout Japan.
Materials and Methods
Data were collected by questionnaire regarding the
schools and children participating in the S-FMR, financial support for the S-FMR, frequency of rinsing,
mouth rinsing agent and fluoride concentration in the
rinsing solution.
Questionnaires were sent to the key persons and
dentists of NPO-JPUF by mail or e-mail nearly every
two years.
Additionally, the estimating number in 2010 were
determined using simple regression analysis and/or
polynominal regression analysis on the basis of the
data from 1994 to 2002, by Stat View 5.0.

In Japan, anti-fluoridationists commonly want to
apply a statement in the WHO technical report.
Go ahead !!
Announcing by NPO-JPUF,
“ Beginning of fluoride mouth rinse is
recommended for Japanese (or Asian)
children in 4-5 years old.”
Tending to mislead by
WHO statement
“ FMR was not recommended for children
below 6 years old, as it might contribute to
the risk of dental fluorosis ??????????????? ”
(Fluoride and Oral Health, WHO, 1994)
In Japan, fluoride use is limited
to topical application, none

Conclusion
These results suggest that cooperation among dental
organizations, dental schools and municipal corporations
can play an important role in order to correct at regional
differences in the S-FMR in Japan.
We propose that a goal, the item with regarding to caries
prevention, for the S-FMR should be adopted in Healthy
Japan 21 at the final assessment in 2010.
Some public health measures based on the health
promotion should be provided in order to make a big jump
for the S-FMR in the future.
