Dental calculus as a proxy for animal microbiomes. [PDF]

Quat Int, 2023
The field of dental calculus research has exploded in recent years, predominantly due to the multitude of studies related to human genomes and oral pathogens. Despite having a subset of these studies devoted to non-human primates, little progress has been made in the distribution of oral pathogens across domestic and wild animal populations.

Dental Calculus [PDF]

Oral Surgery, Oral Medicine, Oral Pathology, 1960
A thorough examination of the mouth is an important part of the general physical examination of the dog. Oftentimes localized disease processes are observed, and frequently symptoms or lesions of more generalized disease conditions are detected in this ...

The Hidden Secrets of the Dental Calculus: Calibration of a Mass Spectrometry Protocol for Dental Calculus Protein Analysis. [PDF]

Int J Mol Sci, 2022
AbstractDental calculus is a solid deposit that forms and accumulates on the tooth surface, entrapping oral microorganisms, biomolecules, and other micro-debris found in the oral cavity. Mass spectrometry analysis of its protein content opens a vista into the subject’s diet, oral flora, and even some aspects of health, thus providing new insight and ...

Multi-omic detection of Mycobacterium leprae in archaeological human dental calculus. [PDF]

Philos Trans R Soc Lond B Biol Sci, 2020
Mineralized dental plaque (calculus) has proven to be an excellent source of ancient biomolecules. Here we present a Mycobacterium leprae genome (6.6-fold), the causative agent of leprosy, recovered via shotgun sequencing of sixteenth-century human ...

Dental Calculus as a Tool to Study the Evolution of the Mammalian Oral Microbiome. [PDF]

Mol Biol Evol, 2020
Dental calculus, the calcified form of the mammalian oral microbial plaque biofilm, is a rich source of oral microbiome, host, and dietary biomolecules and is well preserved in museum and archaeological specimens. Despite its wide presence in mammals, to

Metagenomic analysis of ancient dental calculus reveals unexplored diversity of oral archaeal Methanobrevibacter. [PDF]

Microbiome, 2021
Background Dental calculus (mineralised dental plaque) preserves many types of microfossils and biomolecules, including microbial and host DNA, and ancient calculus are thus an important source of information regarding our ancestral human oral ...

The dental calculus metabolome in modern and historic samples [PDF]

Metabolomics, 2017
Introduction Dental calculus is a mineralized microbial dental plaque biofilm that forms throughout life by precipitation of salivary calcium salts. Successive cycles of dental plaque growth and calcification make it an unusually wellpreserved, long-term

An unusual presentation of dental calculus.

J Indian Soc Periodontol, 2019
Calculus is a mineralized bacterial plaque that is formed on natural teeth surfaces where there is constant supply of saliva. Dental calculus is commonly seen over the buccal surfaces of maxillary molars and lingual surfaces of mandibular anterior teeth where the salivary duct opens into the oral cavity.

Auxiliary Diagnosis of Dental Calculus Based on Deep Learning and Image Enhancement by Bitewing Radiographs. [PDF]

Bioengineering (Basel)
In the field of dentistry, the presence of dental calculus is a commonly encountered issue. If not addressed promptly, it has the potential to lead to gum inflammation and eventual tooth loss.

Dental Calculus Arrest of Dental Caries [PDF]

Journal of Oral Biology, 2016
An inverse relationship between dental calculus mineralization and dental caries demineralization on teeth has been noted in some studies. Dental calculus may even form superficial layers over existing dental caries and arrest their progression, but this phenomenon has been only rarely documented and infrequently considered in the field of Cariology ...
