Formation of functional HA film and the clinical application through the Powder Jet Deposition method

粉末喷射沉积(PJD)技术可用于在人类牙齿表面形成一层厚厚的羟基磷灰石(HAP)薄膜。本研究旨在探讨PJD羟基磷灰石薄膜对人牙本质盘牙本质通透性的影响。应用HAP膜后牙本质的渗透性明显低于对照组。本研究为临床应用PJD脱敏治疗牙本质过敏症提供了可能。

A powder jet deposition (PJD) process can be used to create a thick hydroxyapatite (HAp) film on a human tooth surface. This study aimed to investigate the in vitro efficacy of the hydroxyapatite film using PJD on the dentin permeability of human dentin discs. The permeability of dentin after application of the HAp films was significantly lower than that of the controls. This study showed the possibilities for the clinical desensitizing effect for dentin hypersensitivity by applying PJD.
