                             ABSTRACT Caries is the most prevalent disease of children and is epidemic in some
                             populations. A risk-based approach to managing caries targets those in greatest
                             jeopardy for contracting the disease, as well as provides evidence-based decisions
                             to treat current disease and control it in the future. This paper outlines key concepts
                             necessary to effectively manage and reduce caries based on the most current science
                             to date. Subsequent articles will outline a roadmap to success in curing dental caries.

    This issue of the Journal provides
caries risk assessment and treatment
procedures for newborns to age 5 (Ra-
mos-Gomez et al.); caries risk assessment
for age 6 through adult (Featherstone
et al.); caries management based on
risk assessment (Jenson et al.); and
dental products available for use in the
CAMBRA approach (Spolsky et al.).
    In summation, the Western CAMBRA
Coalition urges that all dentists imple-
ment CAMBRA in their practices for the
benefit of their patients and the improved
oral health of the nation. The time to do it
is now. The tools and rationale are
