Changes in Suid and Caprine Husbandry Practices Throughout Dynastic Egypt Using Linear Enamel Hypoplasia (LEH) [PDF]
, 2011 Linear enamel hypoplasia (LEH) is the most commonly identified form of enamel defect in teeth. Defined as a deficiency in enamel thickness encountered during dental development, LEH can occur as horizontal lines or depressions of irregular enamel, or ...

Dental anomalies in Pleistocene African hippopotamuses from Olduvai Bed II
The Anatomical Record, EarlyView.Abstract Hippopotamuses are key palaeoenvironmental indicators in African Pleistocene ecosystems due to their ecological dependence on permanent water bodies and their frequent representation in the fossil record. This study examines dental anomalies in Hippopotamus cf. gorgops from several localities in Bed II of Olduvai Gorge (Tanzania), dated to ca.

Enamel-Related Gene Products in Calvarial Development
, 2013 Enamel-related gene products (ERPs) are detected in non-enamel tissues such as bone. We hypothesized that if functional, ERP expression corresponds with distinct events during osteoblast differentiation and affects bone development and mineralization. In

Immediate performance of self-etching versus system adhesives with multiple light-activated restoratives [PDF]
, 2004 Objectives: The purpose of this study was to evaluate the performance of both single and double applications of (Adper Prompt L-Pop) self-etching dental adhesive, when used with three classes of light-activated restorative materials, in comparison to the

The Anatomical Record, EarlyView.Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Enamel of primary teeth - morphological and chemical aspects [PDF]
, 2008 Enamel is one of the most important structures of the tooth, both from a functional and esthetic point of view. Primary enamel carries registered information regarding metabolic and physiological events that occurred during the period around birth and ...

The Anatomical Record, EarlyView.Abstract Nineteenth century excavations of the Ciply‐Malogne Phosphatic Chalk Formation in Hainaut, Belgium, yielded over 50 partial mosasaur skeletons, the majority of which were referred to the species Mosasaurus lemonnieri Dollo, 1889. In the years since, this taxon has experienced a complicated taxonomic history, and its exceptional hypodigm has ...

Cristid obliqua morphology as a correlate of diet in lorisoids
The Anatomical Record, EarlyView.Abstract Methods for elucidating dietary patterns from dental morphology have provided much insight into molar form, function, and diet in extinct taxa. However, many methods rely on the collection of homologous landmarks (like shearing crest lengths), or computationally intensive and nuanced metrics that capture shape (like dental topography). Here, a

Changes in the Enamel Protein during Enamel Formation
THE JOURNAL OF THE STOMATOLOGICAL SOCIETY,JAPAN, 1973 幼若エナメル質中に含まれている有機質のほとんどを占めている蛋白質は多成分系である事が知られている。それらのうちのどの成分が生理的に重要なのかを明らかにする目的で, 先ずラット幼若エナメル蛋白質についてゲル濾過クロマトグラフィーとSDS-ポリアクリルアミドゲル電気泳動を行なって, 石灰化の進行に伴う蛋白質のパターンの変化を調べた。続いて, ラットに3H-prolineを静注し, そのエナメル質への取込みの時間的な変化をゲル濾過クロマトグラフィーとポリアクリルアミドゲル電気泳動を行なって調べた。その結果は若いstageのmain componentである分子量約20, 000のproline, glutamic acid, histidineに富む成分が初期に多く脱却し, 石灰化が進むに従って分子量15,
