Introduction: Microleakage is a critical issue impacting the success of zirconia crown restorations. This study compares the effectiveness of self-adhesive resin cement, resin-modified glass ionomer cement, and glass ionomer cement in minimizing microleakage, aiming to enhance the longevity and reliability of zirconia crowns systems.
Materials And Methods: Thirty extracted premolars were collected, and all-ceramic preparation was done. Prepared teeth were randomly divided into three groups (10 each): Group A (self-adhesive resin cement), Group B (resin-modified glass ionomer cement), and Group C (glass ionomer cement). The samples underwent thermocycling, were sectioned mesiodistally and buccolingually, and submerged in a solution of methylene blue. Under a stereomicroscope, the surface of each segment was digitally imaged. A five-point grading system was used to assess microleakage. Data were statistically analyzed using two-way ANOVA, Kruskal-Wallis, and Mann-Whitney tests (: 0.05).
Result: Microleakage with all the cement was comparable with no significant difference. The adhesive resin cement showed the least microleakage followed by resin-modified glass ionomer cement and the conventional glass ionomer cement, although insignificant.
Conclusion: Resin cement, amongst all the adhesive cement, had the least microleakage; however, it was statistically insignificant.

Objective: Understanding the sealing ability of restorative materials to prevent microleakage and its consequent complications-such as secondary caries, postoperative sensitivity, and restoration failure-is imperative in clinical dentistry. This study aims to compare the microleakage performance of four restorative materials-bioactive composite resin (Activa Pronto), alkasite restorative (Cention N), compomer (Dyract Flow), and glass ionomer cement (Type 2 GIC)-in Class V cavities of extracted premolar teeth.
Materials And Methods: Forty non-carious, intact premolar teeth were selected and prepared with standardized Class V cavities.

Objective Proper seal achieved via placement of an effective intraorifice barrier curtails the occurrence of post-bleaching consequences and reinforces the cervical tooth structure. Hence, our present study aims to evaluate the effectiveness of three different light-cure biomaterials as an intraorifice barrier. Methodology Forty-eight sound human premolars were obtained, and root canal treatment procedures were accomplished according to the standard protocol.
