Abstract

Purpose: The purpose of these studies was to compare the esthetic outcome and the infiltration capacity of three resin composite sealers: Biscover LV (Bisco Dental), Optiguard (Kerr) and Permaseal (Ultradent) to ICON (DMG, America) when treating artificial initial caries lesions with resin infiltration.

Methods: A panel of artificial initial caries lesion were created on buccal and lingual surfaces of 75 extracted human molars. Specimens were randomly assigned to 5 groups: ICON, Biscover, Optiguard, Permaseal and a control group (no infiltration). Teeth were hemi sectioned yielding two halves, each with a panel of artificial caries lesion. Lesions on one hemi section were used to assess the esthetic improvement following caries lesion infiltration with the 4 resins based on photographs evaluated with a 100-mm visual analogue scale (VAS) by 17 raters. Lesions on opposite hemi section were used to measure the resin infiltration area percentage (IA%) and the resin infiltration depth percentage (ID%) visualized by the confocal laser scanning microscope (CLSM).

Results: The mean IA% and ID% values were significantly higher for ICON, intermediate for Optibond and Permaseal and significantly lower for Biscover. ICON, Optiguard and Permaseal yielded significantly greater average VAS scores compared to Biscover. A moderately large positive correlation was noticed between the average VAS scores and the infiltration measures.

Conclusion: All the resin sealers Biscover, Optiguard and Permaseal infiltrated the artificial initial caries lesions, however ICON resulted in the deepest infiltration depth and largest infiltration area. The esthetic outcome following artificial initial caries lesion resin infiltration with Optiguard and Permaseal was similar to ICON and thus might be adequately used in caries resin infiltration.
