Is there a relation between dental calculus and kidney stone? [PDF]

open access: yes, 2021
Aim: The purpose of this research is to investigate the frequency of dental calculus in patients with kidney stone and without kidney stone. Methodology: Two hundred eighty-seven patients (143 men and 144 women) aged between 18 and 68 (mean age 38.38±13 ...

Fluorescence spectroscopy of dental calculus

open access: yesJournal 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 ...

Quantitative Evaluation of Caries and Calculus with Ultrahigh-Resolution Optical Coherence Tomography

open access: yesBioengineering, 2023
Dental caries on the crown’s surface is caused by the interaction of bacteria and carbohydrates, which then gradually alter the tooth’s structure. In addition, calculus is the root of periodontal disease.

Patients with dental calculus have increased saliva and gingival crevicular fluid fetuin-A levels but no association with fetuin-A polymorphisms

open access: yesBrazilian Oral Research
: Fetuin-A is a potent inhibitor of calcium-phosphate precipitation and of the calcification process, therefore it can also be related with dental calculus.

Are increased salivary carbonic anhydrase VI levels related to the amount of supragingival dental calculus formation and clinical periodontal scores?

open access: yesJournal of Dental Sciences, 2015
Background/purpose: Carbonic anhydrase (CA) VI is a unique salivary isoenzyme that regulates the pH in the oral environment. Its increased levels result in a more-alkaline saliva, hence it was hypothesized to contribute to dental calculus formation ...

Dental Calculus and its role in periodontal diseases

open access: yes, 2023
Dental Calculus has been associated with periodontal disease for a long time but its exact role in relation to the aetiology has always been debated amongst researchers. One of the reasons for this is the inability to differentiate whether it is calculus

The mechanism of dental plaque and dental calculus formation by fibronectin. 4. Demonstration by fibronectin in the dental calculus.

open access: yesNihon Shishubyo Gakkai Kaishi (Journal of the Japanese Society of Periodontology), 1984
歯周病患者の縁上・縁下歯石における fibronectin の分布を免疫組織学的に検索したところ, 同物質は全症例において存在し, その分布様式は一般に糸状菌, 球菌などの菌体に一致して層板状や瀰漫性であった。また, fibronectin の存在部位は歯石の低石灰化とみなすべき部位と一致し, これは fibronectin が, Ca++やPO4---との反応性が強固で, octacalcium phasphote から hydroxyapatite への成長を著しく阻害するという実験的事実とよく符号する所見であった。

Investigating Biases Associated With Dietary Starch Incorporation and Retention With an Oral Biofilm Model

open access: yesFrontiers in Earth Science, 2022
Dental calculus has proven to contain a wealth of information on the dietary habits of past populations. These insights have, to a large extent, been obtained by the extraction and identification of starch granules contained within the mineralised dental
