Microbial differences between dental plaque and historic dental calculus are related to oral biofilm maturation stage

Microbiome, 2019
Background Dental calculus, calcified oral plaque biofilm, contains microbial and host biomolecules that can be used to study historic microbiome communities and host responses. Dental calculus does not typically accumulate as much today as historically,

Dental calculus detection using the VistaCam [PDF]

Clinical and Experimental Dental Research, 2016
AbstractThe VistaCam® intra‐oral camera system (Dürr Dental, Bietigheim‐Bissingen, Germany) is a fluorescence system using light emitting diodes that produce a 405‐nm violet light. This wavelength has potential application for detection of dental calculus based on red emissions from porphyrin molecules.

Exploring the potential of dental calculus to shed light on past human migrations in Oceania [PDF]

Nature Communications
The Pacific islands and Island Southeast Asia have experienced multiple waves of human migrations, providing a case study for exploring the potential of ancient microbiomes to study human migration. We perform a metagenomic study of archaeological dental

Fluorescence spectroscopy of dental calculus

Journal of Periodontal Research, 2004
Background:  Correct diagnosis of the presence and extent of subgingival calculus is important for periodontal treatment planning and reassessment after periodontal therapy. Traditional tactile methods often lack sensitivity. The present investigation shall contribute to understanding the fundamental fluorescence properties that may be useful for ...

Direct evidence of plant consumption in Neolithic Eastern Sudan from dental calculus analysis [PDF]

Scientific Reports
The Neolithic communities of Eastern Sudan combined intensive pastoralism with plant exploitation as their main subsistence strategies. However, to date, it remains unclear which plant species were part of the human diet during the Neolithic.

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 ...
