Long-term stability of dental adhesive incorporated by boron nitride nanotubes

Adhesive dentistry has advanced significantly over the past ten years, although premature reductions in bond strength, interface and marginal degradation, and biocompatibility of adhesives still pose challenge to the field [1]. These issues may occur due to the presence of non-entangled exposed collagen fibrils in the partially or completely demineralized dentin, after the etching step from acids or acidic resin monomers [2]. The incomplete monomer infiltration into the collagen matrix leads to the presence of mineral-depleted, resin-sparse, water-rich fibrils along the bonded interface challenging the interfacial integrity between resin and dentin [3].
