Human deciduous mandibular molar incremental enamel development. [PDF]

open access: yes, 2010
Quantitative studies of incremental markings retained within human enamel have reconstructed the duration and rate (crown and cusp formation times, initiation and completion, daily enamel secretion rates) of permanent tooth development. This approach has

Intraspecific variation in M1 enamel development in modern humans: implications for human evolution [PDF]

open access: yes, 2008
The timing and sequence of enamel development, as well as enamel thickness, was documented for individual cusps (protoconid, hypoconid,metaconid, entoconid) in 15 unworn permanent lower first molars (M1s) from a sample of modern human juveniles.

Deciphering the functions of Stromal Interaction Molecule-1 in amelogenesis using AmelX-iCre mice

open access: yesFrontiers in Physiology, 2023
Introduction: The intracellular Ca2+ sensor stromal interaction molecule 1 (STIM1) is thought to play a critical role in enamel development, as its mutations cause Amelogenesis Imperfecta (AI).

Developmental Defects of Enamel in Primary Teeth and Association with Early Life Course Events: A Study of 6--36 Month old Children in Manyara, Tanzania. [PDF]

open access: yes, 2013
Children with low birth weight show an increased prevalence of developmental defects of enamel in the primary dentition that subsequently may predispose to early childhood caries (ECC).Focusing 6--36 months old, the purpose of this study was to assess ...

The Importance of Connexin 43 in Enamel Development and Mineralization

open access: yesFrontiers in Physiology, 2018
During enamel development, formation of hydroxyapatite crystals and regulation of pH in the enamel matrix require massive transport of ions. Both ameloblasts and adjacent dental epithelial cells in the stellate reticulum co-express several transmembrane ...

MORPHOLOGY AND STRUCTURAL CHARACTERIZATION OF HUMAN ENAMEL AND DENTIN BY OPTICAL AND SCANNING ELECTRON MICROSCOPY [PDF]

open access: yesJournal of IMAB, 2019
Purpose: The aim of this paper is to visualize and examine the structural features of enamel and dentin by observations in optical and scanning electron microscopes. Material/Methods: Optical microscopic investigations were carried out on crown and root

Emissivity evaluation of human enamel and dentin

open access: yesFrontiers in Physiology, 2022
Background: Human enamel and dentin temperatures have been assessed with non-contact infrared imaging devices for safety and diagnostic capacity and require an emissivity parameter to enable absolute temperature measurements.
