Abstract
Aim: To Compare and evaluate the microleakge of newly introduced Glass Hybrid restorative system(Equia Forte) with alkasite based restorative material(Cention N).
 Materials and Methods: 30 premolars free of caries or any other defects and extracted for orthodontic reasons were chosen for the study. Subsequently class I cavities were prepared and teeth were randomly assigned into two experimental groups (n = 15) and restored using EQUIA FORTE and CENTION N respectively. All the specimens were subjected to thermocycling. Specimens were stained with 0.6% RhodamineB dye and evaluated for dye penetration under stereomicroscope.
 Results: Equia Forte showed lesser leakage than compared to Cention N.
 Conclusion: The study therefore concluded that EQUIA FORTE to have lesser microleakage compared to CENTION N, thereby having better sealing ability.
Highlights
Over the past years esthetic dentistry has shown considerable progress leading to the development of a number of improved restorative materials

Marginal gap formation contributes to microleakage permitting the passage of oral fluids, ions and bacteria leading to post-operative sensitivity, pulpal inflammation and recurrent caries [1]
Summary
Over the past years esthetic dentistry has shown considerable progress leading to the development of a number of improved restorative materials. Marginal gap formation contributes to microleakage permitting the passage of oral fluids, ions and bacteria leading to post-operative sensitivity, pulpal inflammation and recurrent caries [1]. Cention N (IvoclarVivadent; Schaan, Liechtenstein) is a tooth-coloured, basic filling material for bulk placement in retentive preparations with or without the application of an adhesive. It is an “alkasite” a new category of restorative material, like compomer or ormocer and is essentially a subgroup of the composite resin (Samanta, 2017) [2,3]
