Nanodiamond-Gutta Percha Composite Biomaterials for Root Canal Therapy.

Root canal therapy (RCT) represents a standard of treatment that addresses infected pulp tissue in teeth and protects against future infection. RCT involves removing dental pulp comprising blood vessels and nerve tissue, decontaminating residually infected tissue through biomechanical instrumentation, and root canal obturation using a filler material to replace the space that was previously composed of dental pulp. Gutta percha (GP) is typically used as the filler material, as it is malleable, inert, and biocompatible.

Nanodiamond-mediated drug delivery and imaging: challenges and opportunities.

Introduction: The field of nanoparticle-based therapeutic systems is rapidly expanding encompassing a wide variety of practices ranging from detection to diagnosis to treatment. Recently a great potential of nanodiamond (ND) particles as a multimodal imaging/therapy platform has been demonstrated.

Areas Covered: This review describes a unique set of properties of ND particles attractive for drug delivery and imaging applications and highlights the most recent ND-based multimodal imaging/therapy approaches and related biocompatibility studies.
