Profilometric and scanning electron microscopy analysis comparing hydroxyapatite and zinc oxide nanoparticles for erosion resistance.

ABSTRACT:

Background

Dentin hypersensitivity (DH) is a prevalent dental issue characterized by sharp pain of short duration. Although the exact cause of DH remains debated, the hydrodynamic theory explains its mechanism. Furthermore, various methods, such as potassium-containing toothpaste, mouthwash, and chewing gum, have been attempted to address DH. However, recent research has explored the potential of nanoparticles (NPs) for DH treatment due to their biocompatibility and bioactive properties.

Methods

Twenty-seven sound premolars extracted for orthodontic purposes were utilized in the present study to obtain 27 mid-coronal dentin discs. These discs were then etched with 37% orthophosphoric acid for 20 s to expose dentinal tubules (DTs) and simulate DH. Subsequently, dentin discs w
