INTRODUCTION Repeated bacterial acid challenges to tooth enamel result in loss of the mineral component. The resulting spaces decrease the refractive index to light giving the appearance of a white lesion. Resin infiltration fills subsurface enamel voids and increases the refractive index of white spot lesions to more closely match the surrounding enamel and improve esthetics. Currently, there is a lack of information regarding the color stability of resin-infiltrated enamel following multiple acid challenges.
