The Potential of Hydroxyapatite Toothpaste towards the Hypersensitive Tooth

Abstract

Dental hypersensitivity is a communal problem that we may often encounter in the daily life of both men and women, especially in the elderly who can unconsciously affect every daily activity. Dentin hypersensitivity is defined as sharp pain caused by stimulation of exposed dentin and unprotected dentin by enamel which can be caused by attrition, abrasion, crown fracture, gingival recession, and orthodontic trauma. Aim: The aim of this study was to analyse the potential of hydroxyapatite toothpaste towards the hypersensitive tooth through literature review. Method: This study analyzed 35 journals from each database PubMed, Ebsco, Google Scholar, ResearchGate, Wiley Online Library, and other international journal websites with keywords hydroxyapatite, hypersensitive dentin, remineralization. Conclusion: Toothpaste containing hydroxyapatite was more effective than toothpaste without hydroxyapatite in inducing tooth remineralization process. The use of toothpaste containing hydroxyapatite in the long term and routine for 15 days is more effective in reducing dental hypersensitivity.

Regenerative and Protective Effects on Dental Tissues of a Fluoride–Silicon-Rich Toothpaste Associated with a Calcium Booster: An In Vitro Study

“…Numerous carbon groups are present in the crystals of hydroxyapatite as carbonates. Carbonate can either replace the OH-ions in the hydroxyapatite structure to generate type A carbonate apatite crystals or the PO4 3- ions to form type B apatite crystals [ 34 ]. Carbonate ions can also replace prevalently occurring phosphate groups, producing a persistent coating of carbonate–hydroxyapatite deposition on the enamel surface [ 35 ].…”
