Omya has developed Omyadent 200-OG (INCI: Hydroxyapatite (and) Calcium Carbonate), which contains a grade of particles that are efficient for desensitizing toothpaste applications.
The co-processed mineral has an outer shell of hydroxyapatite, the main constituent of enamel and dentin, and can interact with the tooth surface to make it more resistant to painful stimuli.
The mineral is modified with the proper technology to create new surface features and the particles become porous; Omyadent 200-OG has been developed to address dentin hypersensitivity (DH).
This discomfort is because of exposed tubules within the dentin, most commonly due to receding gums or enamel wear. Symptoms are characterized by a reaction to certain triggers such as hot, cold, sweet or sour foods and beverages. This can induce the movement of fluid within the tubules, aggravating nerves in the pulp and causing short, sharp pain. As a result, those consumers that are affected start to avoid certain products.
DH can be treated by blocking dentin tubules, preventing the stimuli and dentinal fluid movement. With its tailored small particles, Omyadent 200-OG penetrates the tubules and occludes them while the hydroxyapatite shell makes the tubules resistant to an acid attack. The hydroxyapatite shell ensures improved acid-resistance versus calcium carbonate and makes Omyadent 200-OG survive acid attacks.
