Nihon 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。

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 ...

Molecular Oncology, EarlyView.This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

An unusual presentation of dental calculus
Journal of Indian Society of Periodontology, 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.

Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model
FEBS Open Bio, EarlyView.This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.

Detection, removal and prevention of calculus: Literature Review
Saudi Dental Journal, 2014 Dental plaque is considered to be a major etiological factor in the development of periodontal disease. Accordingly, the elimination of supra- and sub-gingival plaque and calculus is the cornerstone of periodontal therapy.
