A review of the literature on the impact of dental care on the inciden
ce of dental caries in children and adults suggests that the effect is
small, Dental services were relatively unimportant in explaining the
recent decline in caries in 5- and 12-year-olds. An important contribu
tion of the dental services to the decline in caries was a change in t
he diagnostic and treatment criteria. The role of dentistry in reducin
g dental caries may lie mainly in the non-personal health services, Kn
owledge of the life history and patterns of caries attack rates within
populations and individuals could be used as a benchmark against whic
h interventions can be assessed. Different teeth and tooth sites an af
fected differentially at different levels of dental caries, This truis
m may appear obvious but it is not used to evaluate the effectiveness
and quality of dental treatment. A working rule is that ''As caries pr
evalence falls, the least susceptible sites (proximal and smooth surfa
ces) reduce by the greatest proportion, while the most susceptible sit
es (occlusal) reduce by the smallest proportion.'' There is a specific
relationship between the mean DMFT and mean DMFS, and the percentage
of caries-free subjects and the frequency distribution of subjects wit
h different levels of caries. Furthermore, the best predictor of carie
s at older ages is DMFT at a younger age. Caries levels follow trend l
ines for each level of caries. As the mean DMFT declines so post-erupt
ive time increases for initiation of caries and the progression rates
of caries through enamel decreases. This is true regardless of the pre
sence of fluoride.
