Abstract

Objective: The study aimed to evaluate and compare the shear bond strength, degree of conversion, microleakage, sorption, and solubility between Cention N and Tetric N Ceram Bulk Fill restorative materials. Study Design: Quasi-experimental study. Settings: de’ Montmorency College of Dentistry, University College of Dentistry, and Institute of Dentistry, CMH Lahore Medical College, Lahore Pakistan. Duration: From January 2022 to December 2024. Methods: The study was conducted after the approval of IRB on a sample of 111 extracted molars and premolars, which were divided into four groups, each treated with different combinations of adhesives and restoration: Group A (Cention N with total-etch), Group B (Cention N with self-etch), Group C (Tetric N Ceram with total-etch), and Group D (Tetric N Ceram with self-etch). The samples were subjected to micro shear bond strength testing, FTIR spectroscopy, microleakage using dye penetration, and water sorption and solubility tests. Statistical analyses were performed using ANOVA and post-hoc Tukey tests. Results: Cention N demonstrated significantly higher micro shear bond strength (p<0.001) compared to Tetric N Ceram. The degree of conversion was highest in Tetric N Ceram (p=0.008). Microleakage analysis revealed that Cention N with adhesive showed the least leakage (p=0.218), while water sorption and solubility were lowest in Cention N (p<0.001 for both). Conclusion: Cention N outperformed Tetric N Ceram in terms of micro shear bond strength, microleakage, sorption, and solubility, making it a more reliable and durable restorative material. However, factors such as ease of use, cost, and patient comfort should also be considered.
