Role of hydroxyapatite during tooth whitening

hydroxyapatite, tooth bleaching, dentin sensitivityAbstract
Hydroxyapatite (HAp) is a biocrystal considered a multifunctional biomimetic active ingredient, which has currently gained wide acceptance in the biomedical area; in addition, it is used in the dental area through commercially available products containing synthetic hydroxyapatite in powder form with different particle sizes, such as desensitizers, toothpastes, and mouthwashes. There is also evidence of its applicability in tooth whitening, since the treatment has disadvantages, one of the main ones being the affectation of the mineralized substance of tooth enamel and tooth sensitivity. Based on the previous statement, studies have shown that the microscopic effects on the surface enamel associated with whitening could be repaired with the use of products based on HAp crystals. Therefore, the aim of this literature review was to report on the role of hydroxyapatite during tooth whitening, considering three general aspects: its remineralizing, desensitizing, and whitening effects.
