Purpose:
To evaluate the microtensile bond strengths (microTBS) of two core composites; LuxaCore and MultiCore Flow, to root canal dentin when using different adhesive systems.
Methods:
Bonded specimens were allocated into six groups (N=20) according to the combination of two core composites and three adhesive systems (All-Bond 2, Excite DSC and Contax). The materials were used according to the manufacturers' instructions. The microTBS were measured using a universal testing machine with a crosshead speed of 1 mm/minute. Data were analyzed utilizing two-way ANOVA (alpha=0.05).
Results:
Excite DSC showed the highest mean microTBS, which was significantly different from those of All-Bond 2 and Contax in LuxaCore groups. Excite DSC showed the highest microTBS but significant differences (P=0.154) were not detected in MultiCore groups. There were significant differences in microTBS between two resin composites (P<0.001). With Contax, microTBS of MultiCore Flow to dentin were significantly higher than those of LuxaCore (P=0.003).

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
