The diagnosis of occlusal caries and the initiation of more effective treat
ment present a considerable challenge. Caries not only has decreased in pre
valence, but also has changed in pattern and in progression because of the
increased use of fluorides, Correct diagnosis is crucial, distinguishing le
sions that can be arrested by noninvasive treatment from those that may jus
tify restorative treatment. For incipient lesions, it is necessary to impro
ve the patient's home care preventive methods, to apply fluoride or other p
rophylactic agents, or even to seal fissures, preserving the maximum amount
of sound tooth structure. This article discusses the diagnosis of occlusal
caries and noninvasive treatments for the management of early caries.
