Официальное название

Comparative Evaluation of Nano Hydroxy Apatite Varnish and Potassium Nitrate Gel Versus Fluoride Varnish as Non-invasive Treatment of Dentin Hypersensitivity in Permanent Teeth With Molar Incisor Hypo-mineralization: Randomized Clinical Trial

Обзор

This clinical study main goal is to investigate the effectiveness of nano hydroxy apatite crystal varnish and potassium nitrate gel as a non invasive approach in managing Dentin Hypersensitivity in MIH-affected teeth.

Подробное описание

This randomized clinical trial study aims to investigate the effectiveness of nano-hydroxy apatite crystal varnish, and potassium nitrate gel compared to fluoride varnish, in reducing dentin hypersensitivity, improving a child's oral hygiene.
