The Effect of Toothpastes Containing Hydroxyapatite, Fluoroapatite, and Zn-Mg-hydroxyapatite Nanocrystals on Dentin Hypersensitivity: A Randomized Clinical Trial.

ABSTRACT:

Aims

The aim of this study was to compare the effect of toothpastes containing hydroxyapatite (nHAP), Zn-Mg-hydroxyapatite (nZnMgHAP), and fluorapatite (nFAP) nanocrystals on dentin hypersensitivity (DH) associated with noncarious cervical lesions.

Materials and methods

Thirty consenting volunteers aged 35-45 years with DH were enrolled in a double-blind, parallel study, randomly assigned to the nHAP group (n = 10), the nZnMgHAP group (n = 10), or the nFAP group (n = 10), and instructed to use the toothpaste twice daily for one month. The primary outcome was Schiff scores at baseline and after 2 and 4 weeks.

Results

All patients fulfilled the study requirements, and no adverse effects were registered. A reduction in DH was registered in 90%, 100%,
