Collagen analysis in human tooth germ papillae [PDF]

Brazilian Dental Journal, 2006
The extracellular matrix (ECM) performs a very important role in growth regulation and tissue differentiation and organization. In view of this, the purpose of this study was to analyze the collagen, the major organic component of dental pulp ECM, in papillae of human tooth germs in different developmental phases.

Unveiling a New Link: Cholesterol Deficiency in Smith–Lemli–Opitz and Niemann–Pick C as a Driver of Ciliopathies

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The ciliopathies are a group of genetic disorders caused by defective function of either the primary cilia (a large number) or the motile cilia (a much smaller number). These have been defined as diseases with mutations in genes encoding individual ciliary or cilia‐associated proteins.

Dynamic expression of Mage-D1 in rat dental germs and potential role in mineralization of ectomesenchymal stem cells

Scientific Reports, 2022
Mage-D1 (MAGE family member D1) is involved in a variety of cell biological effects. Recent studies have shown that Mage-D1 is closely related to tooth development, but its specific regulatory mechanism is unclear.

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

The Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

C-Jun N-terminal kinase (JNK) pathway activation is essential for dental papilla cells polarization.

PLoS ONE, 2021
During tooth development, dental papilla cells differentiate into odontoblasts with polarized morphology and cell function. Our previous study indicated that the C-Jun N-terminal kinase (JNK) pathway regulates human dental papilla cell adhesion ...

Whole Tooth Regenerative Therapy Using a Bioengineered Tooth Germ [PDF]

Current Oral Health Reports, 2013
Dental disorders, including dental caries and periodontal disease, can cause fundamental problems for oral functions, such as enunciation, mastication and occlusion, as well as general health issues. Tooth regenerative therapies for tissue repair and whole tooth replacement are currently being developed as novel treatment approaches.

Fusion of a primary mandibular lateral incisor and canine: A rarity

Archives of Medicine and Health Sciences, 2017
Fusion is a developmental anomaly of dental hard tissues characterized by the union of two adjacent teeth. It may be complete with the formation of an abnormally large tooth or incomplete with the union of crowns or roots only.
