Decayed or damaged tooth structure is widely being repaired with the resin
based dental composites (RBCs) in the clinical practice. However, relatively high failure rate
and short lifespan are common in the case of the larger posterior teeth restorations,
caused by the polymerization shrinkage of RBCs. In order to reduce the polymerization
shrinkage inorganic dental inserts were introduced. The aim of this study was to fabricate
dental inserts based on hydroxyapatite doped with 5 mol. % of magnesium ions (MgHAP)
and determine their bonding ability with a restorative material widely used in the clinical
practice – Clearfil Universal adhesive. The MgHAP powder and insert were characterized
using energy dispersive X-ray (EDX) analysis, X-ray diffraction (XRD) analysis and scanning
electron microscopy (FE-SEM). Bonding ability of the inserts with restorative material was
measured by shear bond strength (SBS) test, and the type of fracture was determined by
the optical microscope.... The obtained mean SBS value of the MgHAP inserts was 12.7 MPa,
with mostly cohesive type of the fracture present. These inserts present promising dentin
substitutes for application in the restorative dentistry.
