Summary Experimental studies have been made of mineralization in developing human dental calculus, formed in vivo on polyester strips attached to the teeth. The findings suggest a close parallelism between calcification process in this exogenous deposit and in calcified tissues. The microorganisms and intermicrobial substance first laid down serve as the organic matrix, which undergoes a series of chemical and morphological changes prior to mineralization. Calcification within this matrix… 
Dental calculus may be defined as the solid, hard mass of calcified material tha t deposits on and adheres to oral structures. These oral structures include the natural dentition and both permanent
Lipid and Calculus Matrix Calcification In Vitro
Lipid is necessary for calcification of a calculus matrix. Matrix was prepared by decalcification of dental calculus. The matrix calcified when it was exposed to a metastable calcium phosphate
Experimental dental calculus formation in intraperitoneal dialysis bags.
Abstract Dialysis bags containing pure strains of oral bacteria and teeth, or containing teeth only, were implanted into the peritoneal cavities of rats for as long as 17 months. Within several
SYNOPSIS A method is described for preparing sections of teeth. In caries-prone enamel it involves the destruction of the component of the matrix which commonly occurs in prism cores, and which is
Scanning electron microscopy of dental calculus
The morphologic structure of anorganic dental calculus was studied by means of the scanning electron microscope and it is speculated that the crystal patters in type B centers might represent other known forms of calcium phosphates present in calculus, such as octacalcium phosphate, whitlockite and brushite.
Electron Microscopy of Intracellular Mineralization of Oral Filamentous Microörganisms in Vitro
The work being reported dealt with an electron-microscopic study of pure cultures of oral filamentous microorganisms that were experimentally mineralized in a calcifying solution.
Ultrastructure of the approximal dental plaque and the underlying normal and carious enamel.
Abstract An electron microscopical study has shown that approximal normal enamel surfaces, devoid of any microbial aggregation, are covered by an acquired pellicle in erupted teeth. The first stages
Observations of the surface of dental calculus using scanning electron microscopy.
The authors report here on the interesting results about the morphology of calculus obtained by observing the surface structures of calculus by scanning electron microscopy.
Stages of calcium phosphate crystallisation during calculus formation.
Tetracalcium hydrogen triphosphate dihydrate occured in addition to brushite in the earliest stages of development of dental calculus and was also one of the main constituents in old calculus.
Mineralization of Bacteria
A variety of viable and non-viable bacteria became mineralized with hydroxyapatite when implanted in dialysis bags in the peritoneal cavities of rats, analogous to that in the formation of oral calculus.
