Caries infiltration of noncavitated white spot lesions: A novel approach for immediate esthetic improvement.

The earliest evidence of demineralization on the smooth enamel surface of a crown is a white spot lesion. The conventional treatment of these white spot lesions includes topical fluoride application, iamproving the oral hygiene, and use of remineralizing agents. The following article illustrates the use of a novel approach to treat smooth surface noncavitated white spot lesions microinvasively based on infiltration of enamel caries with low-viscosity light curing resins called infiltrants. This treatment aims upon both the prevention of caries progression and improving esthetics, by diminishing the opacity.
