Comparison of Resin Infiltration Technique with Conventional Preventive Applications on Occlusal Fissures in Terms of Chemical Analysis and SEM.

Objective: To compare the subsurface mineral loss preventing capability of resin infiltration technique with topical fluoride and fissure sealant applications to demineralized occlusal fissures under simulated oral conditions.

Materials And Methods: Occlusal surfaces of 64 extracted intact human third molars were demineralized. Next, the teeth were classified into four groups according to preventive applications (n = 16): G1, Specimens used as the control group with no preventive treatment; G2, Topical fluoride application (APF Gel/ DEEPAK); G3, Fissure sealant application (ClinproTMSealant/ 3M ESPE); and G4, Resin infiltration technique (Icon/ DMG).

Effect of resin infiltration on the color and microhardness of bleached white-spot lesions in bovine enamel (an in vitro study).

Objectives: The aim of this study was to investigate both the effect of resin infiltration on the color and microhardness of white spot lesions (WSLs) that treated with bleaching and to analyze the penetration of the infiltrant.

Materials And Methods: In each of 135 bovine enamel specimens, WSLs were produced. The samples were then randomly divided into three groups (n = 45): group I, bleached; group II, resin-infiltrated; group III, bleached and resin-infiltrated.
