In vitro Evaluation of Resin Infiltrant Penetration into White Spot Lesions of Deciduous Molars.

Introduction: Caries Infiltration is a recent microinvasive restorative technique that permits treatment of non-cavitated demineralized lesions, known as White Spot Lesions (WSL).

Aim: To evaluate the extent of penetration of a commercially available resin caries-infiltrant into natural WSL occurring in deciduous tooth enamel.

Materials And Methods: Deciduous molars with natural WSL on any smooth surface were selected and sectioned into halves to yield equal control and experimental groups.
