“…This is comparable to previous studies that reported Zirconomer showing higher microleakage scores as compared to composite and amalgam in class I cavities of non-carious permanent molars (30). Another study reported that Zirconomer had a higher microleakage as compared to nano-ionomer in class V cavities of noncarious premolars (22).…”

Background: Microleakage is defined as the passage of bacteria, fluid, molecules or ions between the cavity walls and restorative material. There are limited studies in the literature that have compared the microleakage of the newer restorative materials. Therefore, the aim of this study is to compare and evaluate microleakage in Class II cavity in primary molars restored with glass ionomer cement, zirconomer and cention N using stereomicroscope. Method: Standardized Class II cavities were prepared on the extracted primary molars All the prepared samples were divided into 3 experimental groups and were restored as follows: Group I- GIC (GC Universal Restorative); Group II- Zirconomer (SHOFU Inc., Kyoto, Japan) and Group III- Cention-N (Ivoclar Vivadent). The restored teeth were thermocycled, immersed in methylene blue dye and sectioned along the mesiodistal direction. The dye penetration at the occlusal surface and cervical surface was evaluated and compared using a stereo-microscope. Data was analysed using Krushal-Wallis test (Non-parametric ANOVA). Results: Among the three restorative materials, Cention N as compared to GIC and Zirconomer showed least microleakage at both the occlusal surface and cervical surface. Conclusion: Cention N a newer restorative material displayed lesser microleakage as compared to GIC and Zirconomer.

“…A recent study by Asafarlal ( 26 ) investigated the microleakage of three different GICs-Zirconomer, Fuji IX Extra and Ketac Molar quantitatively. After immersion the teeth individually in 0.5% methylene blue dye for 24 hr, the samples were dissolved in 2ml of 65% nitric acid, the solutions were centrifuged and then spectrophotometer was used to assess the dye penetration.…”

“…The results of the dye concentration in the experimental solutions showed that the microleakage value of Zirconomer was higher compared to the other GICs. This was believed to be owing to large size of the filler particles of zirconia which leading to poor adaptation at the tooth-restoration interface ( 26 ).…”

ObjectiveTo evaluate the microleakage of four direct restorative materials.Materials and MethodsSixteen sound bovine incisors were chosen and randomly divided into four groups; Group I-Zirconomer, Group II-KetacTM Silver, Group III-FiltekTM Z500 (composite) and Group IV-Dispersalloy® (amalgam). Seven proximal (mesial & distal) cavities, for each material were prepared and restored. All restored samples were stored in 37oC distilled water for 24 hr and then subjected to thermo-cycling process at temperatures between 5-55oC. The samples were immersed in dye solution of 0.5% methylene blue for 24 hr. Each filled cavity was sectioned through the centre of restoration and then studied under a stereomicroscope to assess the marginal leakage. The obtained microleakage scores were statistically analysed.ResultsThe highest mean score of leakage was recorded in Group II-KetacTM Silver followed by Group I-Zirconomer and Group III-FiltekTM Z500 (composite). The lowest mean score of dye penetration was verified in Group IV-Dispersalloy® (amalgam). Statistically, there were significant differences between Zirconomer and other groups of KetacTM Silver and amalgam, whereas the Zirconomer groups had no significant differences with composites. All tested groups showed significant differences with amalgam restorations.ConclusionsThe marginal leakage was evident in all restorative materials. Further studies with clinical trial have to be done.

“…According to a previous research on marginal leakage of Zirconmer and highly viscous GI, the sealing ability of highly viscous GI was much better than Zirconomer. This was thought due to presence of large sized Zirconia particles in Zirconomer that hinders its good adaptation to the tooth surface (13) .…”

Purpose: This study evaluated and compared between effect of heat application on the shear bond strength and microleakage of class I reinforced glass ionomer restorations (EquiaFil Fort, Zirconomer and Resin modified glass ionomer Fuji II LC). Meanwhile, the clinical performance of such materials was assessed. Materials and Methods: Ninety caries free first and second permanent molars were divided into three groups of (30 each) according to the type of the Glass Ionomer Cements used. Each group was further subdivided into three subgroups of (10 each): B 1 for no heat application, B 2 for 20 sec heat application and B 3 for 60 sec heat application. This sample grouping was done twice in shear bond strength and microleakage assessment. A universal testing machine was used to test the shear bond strength for the specimens, while the microleakage test was examined under stereomicroscope. A total of 20 patients with split mouth design participated in this study. Each patient had two fillings according to the material used (Equia and Zirconomer). Restorations of the teeth were evaluated at the same day (base line), one month, and 6 months and were rated according to the USPHS criteria. Results: all heated groups showed higher shear bond strength and microleakage. For secondary caries, post-operative sensitivity and color match, no statistical significance differences were recorded in the clinical performance of Equia and Zirconomer. Conclusion: Application of heat improves bond strength and microleakage of GICs. The clinical outcome of both Equia and Zirconomer were considered satisfactory after 6 months.
