Abstract
<jats:p>Abstract. The article examines the use of nanotechnologies in modern dentistry aimed at the prevention and treatment of dental caries. Special attention is given to medical nano- hydroxyapatite (nano-mHAP), an innovative material characterized by high biocompatibility and effective restoration of tooth enamel. The mechanisms of action of nano-mHAP are presented, including remineralization, filling of microcracks, and repair of damaged areas on the tooth surface. The advantages of using nano-mHAP-based toothpastes for children, adults, and pregnant women are described, including reduced tooth sensitivity, plaque removal, and protection against caries. Research data confirming the high effectiveness of nano-mHAP compared with traditional agents such as fluorides are provided. The article highlights the role of nanotechnologies in improving the quality of dental care and enhancing oral health.</jats:p>
