Comparative Evaluation of Microlekage of Zirconia-Reinforced Glassionomer and Two Conventional Restoratives: An In Vitro Study
Year: 2024
Type: article
Abstract: Background: Dental materials used for permanent restorations are intended toreplace lost and defective dental tissues and be chemically stable and inert inthe oral environment.Aims and Objectives: To compare and evaluate marginal microleakage ofzirconia-reinforced Glassionomer with two conventional restoratives. Toanalyze the microlekage of the cements being tested.Materials and methods: For testing microlekage, class V, cavities were preparedon 60 extracted maxillary premolars. Each set of dentition permanent teeth wasdivided into 3 groups of 20 specimens each to be restored with selectedrestorative material: Group A (Zirconomer), Group B (Hidence, Group C(Posterior Extra). These teeth were subjected to thermo cycling, dye immersion,sectioning, and examination under a Stereomicroscope to assess the degree ofmicrolekage. The scoring was done according to the scoring criteria putforward by Khera and Chan, which were further tabulated and statisticallyanalyzed.Results: Microlekage of 3 groups showed no significant difference.Statistically analyzed using the one-way ANOVA test and the unpaired test, andpair-wise comparison was done using the Turkish multiple postdoc procedure.Conclusion: It can be concluded that Zirconomer-reinforced Glassionomerproved to be a better restorative material than the other cements used in thestudy
