MDM2-Mediated p21 Proteasomal Degradation Promotes Fluoride Toxicity in Ameloblasts

Cells, 2019
Fluoride overexposure is an environmental health hazard and can cause enamel and skeletal fluorosis. Previously we demonstrated that fluoride increased acetylated-p53 and its downstream target p21 in ameloblast-derived LS8 cells. However, p21 function in

p75NTR Promotes Circadian‐Driven Mineralization During Tooth Development via CK2/PER2 Pathway

Cell Proliferation, Volume 59, Issue 5, May 2026.
The diagram illustrates how the circadian rhythm regulates the p75NTR‐CK2‐PER2 axis, driving rhythmic biomineralisation during tooth development. ABSTRACT Circadian rhythm is an essential biological process that synchronises physiological activities with environmental light/dark cycles.

Molar‐Incisor Hypomineralisation in Children: The Essential Role of Paediatricians

Journal of Paediatrics and Child Health, Volume 62, Issue 5, Page 672-677, May 2026.
ABSTRACT Aim Molar‐incisor hypomineralisation is a developmental enamel defect characterised by lower mineral content in the tooth's outer layer, discoloured and structurally fragile teeth that are more prone to sensitivity, breakdown and caries. This review aims to summarise current knowledge on molar‐incisor hypomineralisation and highlight key ...

Ameloblastic carcinoma of maxilla

National Journal of Maxillofacial Surgery, 2012
Ameloblastic carcinoma (AC) is a rare malignant lesion with characteristic histologic features and clinical behavior that dictates a more aggressive surgical approach than that of a simple ameloblastoma. The tumor cells resemble the cells seen in ameloblastoma, but they show cytologic atypia.

EXPRESSION OF OD314 DURING AMELOBLAST DIFFERENTIATION AND MATURATION

, 2005
법랑모세포는 법랑질을 형성하고 유지하는 세포로, 법랑질의 유기기질을 분비하고 법랑질 석회화 과정에도 관여한다. 치아 발생과정에서 법랑모세포의 분화는 순차적인 상피-간엽 상호작용에 의하여 조절되나, 분화나 성숙과정의 정확한 기전은 아직까지 잘 알려져 있지 않다. 최근에 상아모세포에서 처음 발견된 OD314가 치아 발생과정에서 상아질을 형성하는 상아모세포 뿐 아니라 법랑모세포에도 발현된다고 하였다.
