Impact of transparent tray-based application of bioactive glasses desensitizer on the permeability of enamel and dentin to hydrogen peroxide: an in vitro study

摘要

The preparation of customized transparent tray. : Tooth specimens were embedded with alginate impression material with the buccal surfaces exposed; : Gapping discs which were made of light-cured composite resin were placed on buccal reserved areas of the embedded tooth specimens; and : Transparent tray was fabricated with polyvinylacetate plates by a vacuum thermoforming unit at 175 °C on the embedded tooth specimens
