This study aimed to evaluate surface morphology and resin tag penetration of resin infiltration into primary anterior teeth after enamel deproteinization with sodium hypochlorite (NaOCl) prior to phosphoric acid (H3PO4) etching. Ninety primary anterior teeth with non-cavitated caries lesion were devided five groups according to enamel pretreatment as follows, group ¥°-15% hydrochloric acid (HCl) 2min. ; group ¥±-5.25% NaOCl 1min., 35% H3PO4 1min. ; group ¥²-5.25% NaOCl 2min., 35% H3PO4 1min. ; group ¥³-5.25% NaOCl 1min., 35% H3PO4 2min. ; group ¥´-5.25% NaOCl 2min., 35% H3PO4 2min. Fifteen teeth were examined etched surface structure using field emission-scanning electron microscope. Seventy five teeth were infiltrated with resin, maximum penetration depth and percentage penetration were analysed using dual fluorescence confocal microscopy. As the application time of NaOCl increased, ratio of enamel type ¥°, ¥± were increased. Percentage penetration (PP) was higher in group ¥´ than group ¥±, ¥² (p < 0.05). PP of group ¥³, ¥´ did not show any differences. Non-cavitated caries of primary anterior teeth can be treated with resin infiltration. Enamel deproteinization with NaOCl prior to 35% H3PO4 etching could be an alternative of 15% HCl etching in resin infiltration.
