Sažetak
Transverse and. tensile resistance o f a dentin-bonded composite resin restoration was tested. The composite resins (Fluorocore, Coradent and Coracore) were retained routinely by a dentin adhesive (Syntac) on dentin samples. The specimens were mounted on a mechanical testing device, and each o f the 23 specimens was loaded perpendicularly to its long axis. The transverse force was applied at a crosshead speed o f 0.5 mm/min until failure occurred. The next 22 specimens were loaded in parallel with their long axis in the same conditions. All the three materials showed a satisfactory compressive shear bond strength, but transverse resistance was inadequate and restorative pins had to be used.
