Evaluation of the performance of ChatGPT‐4 and ChatGPT‐4o as a learning tool in endodontics

International Endodontic Journal, EarlyView.
Abstract Aims The aim of this study was to evaluate the accuracy and consistency of responses given by two different versions of Chat Generative Pre‐trained Transformer (ChatGPT), ChatGPT‐4, and ChatGPT‐4o, to multiple‐choice questions prepared from undergraduate endodontic education topics at different times of the day and on different days ...

The crucial role of centrioles in tooth growth and development

Journal of the Formosan Medical Association
Background: Tooth development hinged on reciprocal interactions between enamel and dentin, shaping tooth structures. Centrioles influenced cellular direction, critical for stem cell differentiation.

Evidence That Calcium Entry Into Calcium-Transporting Dental Enamel Cells Is Regulated by Cholecystokinin, Acetylcholine and ATP

Frontiers in Physiology, 2018
Dental enamel is formed by specialized epithelial cells which handle large quantities of Ca2+ while producing the most highly mineralized tissue. However, the mechanisms used by enamel cells to handle bulk Ca2+ safely remain unclear.

WDR72 regulates vesicle trafficking in ameloblasts

Scientific Reports, 2022
As the hardest tissue in the human body, tooth enamel formation is a highly regulated process involving several stages of differentiation and key regulatory genes.

A secretory kinase complex regulates extracellular protein phosphorylation. [PDF]

, 2015
Although numerous extracellular phosphoproteins have been identified, the protein kinases within the secretory pathway have only recently been discovered, and their regulation is virtually unexplored.

Melatonin and the Dental Pulp: A Scoping Review

International Endodontic Journal, EarlyView.
ABSTRACT Background In general medicine, melatonin is known to enhance wound healing and promote stem cell differentiation. Its potential relevance in endodontics, however, remains underexplored. Objectives This scoping review aimed to systematically assess the available evidence on the effects of melatonin (a) on dental pulp tissue and (b) on human ...

Summary of the IADR Cariology Research, Craniofacial Biology, and Mineralized Tissue Groups Symposium, Iguaçu Falls, Brazil, June 2012: Gene-environment Interactions and Epigenetics in Oral Diseases: Enamel Formation and its Clinical Impact on Tooth Defects, Caries, and Erosion. [PDF]

, 2013
Characteristics of enamel may influence or modulate individual susceptibility to caries and erosion. These characteristics are defined during development, which is under strict genetic control, but can easily be modified in many ways by environmental ...

The dental plate on bichir pectoral fins: A unique dermal skeletal element bearing individual odontodes with tooth‐like replacement

Journal of Anatomy, EarlyView.
Pectoral fins of bichirs encompass the so‐called dental plates – unique dermal skeletal elements with individual odontodes identical to the oral teeth. Abstract The dermal skeleton appeared early in vertebrate evolution in the form of mineralized skin denticles composed of tooth‐like units—odontodes.

Protocol for generating three-dimensional induced early ameloblasts using serum-free media and growth factors

STAR Protocols
Summary: Adult humans cannot regenerate the enamel-forming cell type, ameloblasts. Hence, human induced pluripotent stem cell (hiPSC)-derived ameloblasts are valuable for investigating tooth development and regeneration.

E-cadherin can replace N-cadherin during secretory-stage enamel development. [PDF]

PLoS ONE, 2014
N-cadherin is a cell-cell adhesion molecule and deletion of N-cadherin in mice is embryonic lethal. During the secretory stage of enamel development, E-cadherin is down-regulated and N-cadherin is specifically up-regulated in ameloblasts when groups of ...
