Abstract

Aim: To evaluate the effectiveness of resin infiltration on artificial caries lesion by assessing the depth of resin penetration and the change in microhardness of lesion postinfiltration. Materials and methods: Totally 45 human extracted premolars were used to create an artificial demineralized lesion in enamel using demineralizing solution. A total of 15 samples (group I) were infiltrated with resin. The depth of resin penetration was studied using scanning electron microscope (SEM). Other half (n = 30) of samples was equally divided into three subgroups and Vickers hardness number (VHN) values were obtained to measure the surface microhardness as group IIa—before demineralization, IIb—after demineralization, IIc—postresin infiltration. Results: Mean depth of penetration in group I was 516.8 µm. There was statistically significant increase in VHN values of demineralized lesion postresin infiltration (independent Student's t-test, p < 0.001). Conclusion: Penetration depth of the resin infiltrant was deep enough to render beneficial effects, while significant increase in microhardness was observed postresin infiltration. Clinical significance: Infiltrant used can be considered as a valid treatment option for noncavitated lesions.
