Visualization of enamel rods in hunter-schreger bands and enamel in incipient lesion under polarized and light microscopy

Saudi Journal of Oral Sciences, 2020
Background: An enamel rod is the basic unit of tooth enamel measuring 4 μm wide to 8 μm high and is tightly packed, highly organized mass of hydroxyapatite crystals, which are hexagonal in shape and provide rigidity to the rods and strengthen the enamel.

To What Extent is Primate Second Molar Enamel Occlusal Morphology Shaped by the Enamel-Dentine Junction? [PDF]

PLoS ONE, 2015
The form of two hard tissues of the mammalian tooth, dentine and enamel, is the result of a combination of the phylogenetic inheritance of dental traits and the adaptive selection of these traits during evolution.

Repair of tooth enamel by a biomimetic mineralization frontier ensuring epitaxial growth

Science Advances, 2019
Study shows the repair of enamel via a biomimetic growth frontier that is constructed from calcium phosphate ion clusters. The regeneration of tooth enamel, the hardest biological tissue, remains a considerable challenge because its complicated and well ...

An epithelial signalling centre in sharks supports homology of tooth morphogenesis in vertebrates

eLife, 2022
Development of tooth shape is regulated by the enamel knot signalling centre, at least in mammals. Fgf signalling regulates differential proliferation between the enamel knot and adjacent dental epithelia during tooth development, leading to formation of

An In Situ Evaluation of the Protective Effect of Nano Eggshell/Titanium Dioxide against Erosive Acids

International Journal of Dentistry, 2018
Objectives. Enamel erosion caused by high consumption of acidic drinks poses a significant public health concern. This study was aimed to determine the protective effect of eggshell-titanium dioxide composite (EB@TiO2) against erosive acids on tooth ...

α-Mangostin and lawsone methyl ether in tooth gel synergistically increase its antimicrobial and antibiofilm formation effects in vitro

BMC Oral Health, 2023
Objectives α-Mangostin (α-MG) and lawsone methyl ether (LME) show antimicrobial and anti-biofilm activities. The objectives of this study were to develop a herbal tooth gel containing α-MG and LME plus fluoride and determine its antimicrobial, anti ...

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

, 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.
