Abstract

ABSTRACT:

“AIM: To assess the effect of three lining materials; flowable composite, flowable compomer, and light-curing glass ionomer cement (LCGIC) on microleakage in Class V restoration using packable composite restorations.

MATERIALS AND METHODS: A standardized class V cavity was prepared on buccal surface of 40 young premolar teeth with the cervical margin extending 0.5 mm below the cementoenamel junction, into the dentin. All the samples were randomly divided into 4 groups according to the lining material used: Group I- Control; Group II- flowable composite; Group III- LCGIC and Group IV- flowable compomer. The restored teeth were thermocycled and immersed in 2% methylene blue solution for 24 hours. Each tooth was then sectioned along buccolingual direction. The dye penetration of the occlusal and gingival margins of each section was evaluated by a single observer using a stereomicroscope and statistically analyzed using Kruskal Walis Test and Mann-Whitney U Test.

RESULT: Maximum dye penetration score for Group 1, Group 2 was 3 and Group 3, Group 4 was 1. (p<0.05)

CONCLUSION: Flowable compomer and light cure glass ionomer cement as intermediate lining material can reduce microleakage under packable composite.

Keywords: Compomer, flowable composite, light-curing glass ionomer cement, microleakage, packable composite.”
