Abstract
Dental calculus, a main contributor of periodontal diseases, is mostly composed of inorganic calcium phosphate species such as dicalcium phosphate, whitlockite, octa calcium phosphate, and hydroxyapatite. Under physiological pH 7.4, dicalcium phosphates can gradually interact with calcium carbonate to form hydroxyapatite. Therefore, we hypothesized that aragonite (Arg) could react with dental calculus, facilitating its removal. To assess the reactivity of Arg with dental calculus, we examined the changes in surface morphology, composition, and topography of Arg and dental calculus upon exposure to each other in an aqueous environment. The impact of Arg on the removal of dental calculus was assessed by brushing polished sections of dental calculus, enamel, and dentin with slurries of Arg and measuring the depth of abrasion using a stylus profilometer. Our results demonstrate that Arg can react with dental calculus in aqueous environment. This reaction increases calculus surface roughness which in turn facilitate dental calculus removal by brushing. Aragonite could be a promising abrasive for toothpaste design for management of dental calculus.
Graphical Abstract
This study proposes an innovative approach for the softening and removal of dental calculus based on the use of aragonite. This novel approach, which takes advantage of the chemical reactivity between aragonite and the minerals found in dental calculus, opens the door for developing homecare products that could help patients and clinicians more effectively control and manage dental calculus deposits. Anti-calculus Action. Pyrophosphate and carboxylate inhibit calculus formation by preventing calcium phosphate deposition in plaque.
期刊介绍:
The Journal of Materials Science: Materials in Medicine publishes refereed papers providing significant progress in the application of biomaterials and tissue engineering constructs as medical or dental implants, prostheses and devices. Coverage spans a wide range of topics from basic science to clinical applications, around the theme of materials in medicine and dentistry. The central element is the development of synthetic and natural materials used in orthopaedic, maxillofacial, cardiovascular, neurological, ophthalmic and dental applications. Special biomedical topics include biomaterial synthesis and characterisation, biocompatibility studies, nanomedicine, tissue engineering constructs and cell substrates, regenerative medicine, computer modelling and other advanced experimental methodologies.
