Нано-гидроксиапатит. Преимущества использования в зубных пастах по сравнению с фторидами в понижении гиперчувствительности зубов

Our teeth are constantly subjected to erosion caused by the action of food and drinks (1). These aggressions result in the exposure of dentinal tubules and the underlying nerves to the external environment. Consequently, external stimuli trigger the nerves causing a short and acute pain clinically defined as dental hypersensitivity (2). Individuals with this condition present tooth with open dentinal tubules that are wider and more numerous than nonsensitive teeth (2, 3).

Therefore, it has been reported that the occlusion of tubules is an effective method for the management of dental hypersensitivity (2). Recently, nano-hydroxyapatite (nano-HAp) has been incorporated in oral care formulations and revealed a great potential in the treatment of dental hypersensitivity, as its nanosized particles can be incorporated inside the dentinal tubules. These become sealed and pain associated with dental hypersensitivity is reduced (4, 5).
