Studies of Peculiar Mg-Containing and Oscillating Bioapatites in Sheep and Horse Teeth.

Abstract: New types of biological apatites have been discovered in molar sheep and horse teeth and are divided in two types. In the first and more general type, the release of Mg ions is parallel to the changes in composition of apatite leading to a final stoichiometric ratio of Ca to P ions, going from dentin depth towards the boundary of enamel with air. Inside dentin, another apatite sub-types were discovered with alternating layers of Mg-rich and C-rich apatites. The approximate formal stoichiometric relationships for these peculiar types of bioapatites are suggested. We identified two kinds of ion-exchanges responsible for formation of peculiar apatites. Various combinations of main and minor elements lead to new versions of biological apatites.

This paper presents the discovery and study of unusual biologically-produced apatites (types of minerals) found in the teeth of sheep and horses. These distinct apatites have varying compositions and undergo significant changes, such as the release of magnesium ions and the attainment of an ideal calcium to phosphorus ion ratio.

Discovery and Classification of New Apatites

  • The researchers found unique types of apatites in the molar teeth of sheep and horses.
  • These were classified into two main types, based on their composition and the processes they undergo.
  • The first, more common type demonstrates changes in its composition including the release of magnesium (Mg) ions.
  • This process eventually leads these apatites to achieve a stoichiometric ratio (a characteristic ratio of atoms in a compound) of calcium (Ca) to phosphorus (P) ions.

Composition and Layering

  • The researchers discovered a sub-type of apatite within the dentin (the core material of the tooth) showing a unique pattern.
  • This pattern is of alternating layers of Mg-rich and carbon (C)-rich apatites, suggesting a complex and distinct formation process for these particular types of apatites.
  • Formal stoichiometric relationships were proposed for these peculiar bioapatites, providing a fundamental understanding of their composition and structure.

Identification of Ion-Exchange Processes

  • The research team identified two distinct ion-exchange processes as being responsible for the formation of these unusual types of apatites.
  • An ion-exchange process refers to a chemical reaction where ions of similar charge can be swapped, resulting in a change in the composition of a compound.
  • Understanding these processes provides a valuable insight into the formation and characteristics of these new types of biological apatites.

Variations and New Bioapatites

  • By studying the different combinations of major and minor elements within these apatites, the researchers were able to identify new variants of biological apatites.
  • This substantial variation suggests a vast potential for the discovery of more unique types of biological apatites in the future.

By studying these unusual biological apatites, researchers can gain insights into the complex biochemical processes involved in tooth formation and growth, potentially informing future studies in fields such as dental science, biochemistry, and materials science.
