Abstract

Objectives: To evaluate and compare microleakage around class V cavities restored with silorane and dimethacrylate-based composite resins. Methods: Standard Class V cavities were prepared on the buccal surface of 60 non-carious human molars. Teeth were randomly divided into 3 groups (n=20) depending on the restorative materials used, Silorane-based composite resin (Filtek P90-SIL), dimethacrylate-based composite resin (Solare P-SOLP) and light-cure glass ionomer cement (GC Fuji II LC -LCGIC). The restored teeth with these tooth-coloured restorative materials were thermo-cycled and then immersed in 2% Rhodamine B dye under vacuum pressure for 48 hours. All teeth were bisected longitudinally in a bucco-lingual direction and observed under stereo-microscope at 30X magnification for the evidence of dye penetration. The data were analysed using one-way analysis of variance (ANOVA) and Tukey’s Post Hoc tests (α=0.05). Results: SIL composite resin showed the least microleakage in Class V cavity restorations with a statistically significant difference to SOLP and LCGIC. Sixty five percent of specimens in SIL group, 30% in SOLP group and 5% in LCGIC group showed dye penetration up to one-third of the cavity depth, while 5% in SIL group, 5% in SOLP group and 35% in LCGIC group showed dye penetration up to two-thirds of the cavity depth, and 30% in SIL group, 65% in SOLP group and 60% in LCGIC group showed dye penetration up to the axial wall. Conclusions: Silorane-based composite exhibited least microleakage in restoring class V cavities compared to dimethacrylate-based composite resin and light-cured glass ionomer cement.
