Two Class V cavities were prepared on the buccal and lingual surfaces of each tooth, resulting in a total of 42 cavities. Samples were randomly divided into three groups: Flowable composite with a fifth-generation bonding agent, Cention-N with a fifth-generation bonding agent, and Cention-N without bonding. After restoration, the samples underwent 10,000 thermocycles between 5°C and 55°C. The specimens were then immersed in methylene blue dye. Following longitudinal sectioning, dye penetration was evaluated under a stereomicroscope at ×40 magnification according to Iso11405 criteria. Data were analyzed using the Kruskal-Wallis test.</span></span></span></span></span></span></span><br>

Cention-N without bonding also showed better performance than Flowable composite. At the enamel margin, a statistically significant difference was also found among the groups (P=0.001), with Cention-N plus bonding showing the lowest microleakage.</span></span></span></span></span></span></span><br>
