Conventional root canal therapy has been successful for saving destructive teeth or trauma, which lead to pulpal and periradicular infection1, Root canal therapy is removing dental pulp comprising blood vessels and nerve tissue, decontaminating residually infected tissue through biomechanical instrumentation, and root canal obturation using a filler material Gutta Percha to replace the space that was previously composed of radicular pulp.

Gutta Percha is a filler material which is biocompatible, cost efficiency, ease of removal and malleable used to fill the canal of teeth and sealed using sealer materials. Obturation by Gutta Percha has showed limitations including leakage, root canal reinfection, and poor mechanical properties. To adopt these drop backs, scientists have investigated to use an alternative root filling materials other than Gutta Percha.

Obturation is the crucial step in root canal therapy, therefore inadequate root canal seal around voids during obturation may allow leakage due to absence of bonding between Gutta Percha and the dentinal surface,2.  These voids may permit regrowth of bacterial within the root canals that lead to treatment failures.

Researchers have found that using nano diamonds to reinforce a material used in the procedure could significantly progress outcomes for patients.Nanodiamonds are tiny particles formed as by products of diamond refining and mining. Thousands of times smaller than the width of a human hair,3. Researchers have tried to add an amoxicillin, a broad-spectrum antibiotic commonly used for endodontic infection in order to give an antibiotic action in addition to strength mechanical properties.

This modification in NanoDiamond Gutta Percha achieves great outcomes in future endodontic therapy. NanoDiamond Gutta Percha is a carbon nanoparticles that are approximately (4–6) nm in diameter; for biomedical applications,4. that incorporates numerous important characteristics into a single filler material, improved mechanical properties and antimicrobial, a broad-spectrum antibiotic, such as amoxicillin, activity against oral bacterial. NanoDiamond Gutta Percha can also kill bacteria entering through the lateral canals.


More researches will focus on enhancing the Gutta Percha interface with the surrounding dentinal tissue to improve fracture resistance in weakened endodontically treated teeth, in addition adding antimicrobial properties that will lead to increase durability, NanoDiamond Gutta Percha may enhance the success rate of conventional endodontic therapies and reduce the need for additional treatments, including retreats and apical surgeries.
