Hydroxyapatite is an active ingredient used in oral care products such as toothpastes and mouthwashes for caries prevention. The unique aspect of this ingredient is its high similarity to natural enamel crystallites (biomimetic principle). Recently, a new publication on the current state of research regarding the efficacy of hydroxyapatite in caries prevention was published in the internationally renowned Journal of Dentistry (Elsevier). The publication was co-authored by Prof. Elzbieta Paszynska from PUMS Department of Integrated Dentistry and researchers from Medical University of Bialystok, University of Texas Health, University of Toronto, and Dr. Kurt Wolff GmbH & Co. KG.
