Incidence and Site‐Specific Risk Factors of Jaw Osteoradionecrosis for Head and Neck Patients in the IMRT/VMAT Era: Evidence From a Large, Hospital‐Based Cohort

open access: yesHead &Neck, EarlyView.
ABSTRACT Purpose Osteoradionecrosis (ORN) of the jaw remains a serious late complication of head and neck cancer (HNC) radiotherapy. Although intensity‐modulated radiotherapy (IMRT) and volumetric‐modulated arc radiotherapy (VMAT) are expected to reduce ORN risk, large real‐world data in the modern era are limited.

Hyperemesis gravidarum and oral health: A scoping review

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Hyperemesis gravidarum (HG) is a severe form of nausea and vomiting in pregnancy (NVP), associated with dehydration, nutritional deficiencies, and systemic complications. Although recurrent vomiting, altered dietary patterns, and medication effects might plausibly affect oral health, this relationship has not been comprehensively ...

Holistic bone developing microenvironment engineered apoptotic extracellular vesicles recapitulate multidimensional developmental signatures in adult and senile bone repair

open access: yesInterdisciplinary Medicine, EarlyView.
The developing bone was identified as an M2a‐like macrophage driven immune microenvironment with multidimensional developmental signatures. hME‐ApoEVs were successfully fabricated via stimulating the M2a‐like developing microenvironment in vitro and confirmed its recapitulation of developmental features.

TNF signalling in tooth development

open access: yesCurrent Opinion in Genetics & Development, 2004
Mammalian tooth development has served as an excellent model system to investigate the intricate, interactive mechanisms of patterning, morphogenesis and cytodifferentiation during organogenesis. Teeth develop from interactions between epithelium and neural crest-derived (ecto)mesenchyme that are largely mediated by ligand-receptor signalling.

Tooth Development in Protemnodon eugenii

open access: yesJournal of Dental Research, 1972
Tooth development was studied in a series of pouch-young specimens of Protemnodon eugenii. The single replacing premolar originated from the dental lamina that is directly anterior to the deciduous molariform tooth. Two functionless incisors in each quadrant also were observed during development.

p63 in tooth development

Biochemical Pharmacology, 2011
Recent findings have shown that the development of teeth involves a complex sequence of molecular events in which the p53 family member p63 is involved. Indeed, mice lacking p63 do not have teeth and humans bearing mutations in p63 suffer developmental syndromes that affect tooth morphology and number.

Tooth development in sharks

Archives of Oral Biology, 1970
Abstract The histogenesis of tooth development in five species of sharks was investigated by the use of light microscopy, microradiography and electron microscopy. The highly mineralized outer cap of tissue on shark teeth is not enamel but a form of modified dentine.

MicroRNAs: Modulators of Tooth Development

MicroRNA, 2016
MicroRNAs (miRNAs) are non-coding RNAs that are involved in various biological pathways by regulating gene expression. Teeth develop via reciprocal and sequential interactions between the epithelium and the ectomesenchyme. The speci.c functions of several genes during tooth development are known, and the involvement of their mutations in the ...

Developing a Tooth Restorability Index

Dental Update, 2005
It is generally agreed that the inherent strength of a tooth is dependent on the remaining dentine. It therefore seems logical that preservation of coronal dentine is important to the survival of intra- and extra-coronal restorations. The clinical assessment of the amount of dentine needed for functional requirements and the strategic value of ...

Growth factors and tooth development

The International Journal of Developmental Biology, 1989
The effects of various growth factors on tooth development were studied in organ cultures of mouse embryonic tooth germs. Transferrin was shown to be a necessary growth factor for early tooth morphogenesis. Transferrin was required for the development of bud- and early cap-staged teeth, and it was shown to be the only serum protein that was needed by ...
