Hydroxyapatite, a potent agent to reduce dentin hypersensitivity; systematic review

Abstract

Objective: This study reviews different modes of application of hydroxyapatite for treatment of dentin hypersensitivity via dentinal tubule occlusion.

Methods: Literature search was performed using keywords, “hydroxyapatite and dentin hypersensitivity, hydroxyapatite and dentinal tubule occlusion, hydroxyapatite and dentin permeability, dentinal tubule occlusion” on Pubmed, Science Direct and Web of Science, which involved the results of previous 10 years (2009-2018). After screening, 16 studies were included in systematic review.

Results: The results of in-vitro studies showed that application of hydroxyapatite caused dentinal tubule occlusion leading to reduction in dentin permeability and reduction in dentin hypersensitivity.

Conclusion: Hydroxyapatite has the potential to reduce dentin hypersensitivity via dentinal tubule occlusion within 2-8 weeks.

Keywords: Dentin hypersensitivity, Hydroxyapatite, Dentinal tubule occlusion.
