Papain Gel as a Deproteinizing Agent for Tooth Enamel

Mexican Journal of Medical Research ICSA
Papain gel has been shown to be an effective deproteinizing agent for tooth enamel in several studies. Papain, a proteolytic enzyme derived from papaya, has the ability to break down proteins and remove organic substances adhering to the surface of the ...

Early stages of tooth development in the harbor porpoise Phocoena phocoena

The Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

Human hereditary enamel abnormalities – molecular factors and genetic counselling [PDF]

Romanian Journal of Stomatology, 2019
Defective enamel formation may result either from factors of environmental origin or from genetic abnormality. Such genetically determined enamel malformations have been described in patients with chromosomal anomalies and with inherited single gene ...

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.

Prevalence of dental anomalies and enamel hypoplasia in primary dentition among preschool children of West Godavari District, Andhra Pradesh -A cross - sectional study

Journal of Indian Association of Public Health Dentistry, 2013
Background: It is axiomatic that Pediatric dental anomalies and enamel hypoplasia (E.H) are routinely encountered in primary dentition and early detection and prudent management of the condition facilitates normal occlusal development.

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

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.

Anatomy and variation in the paraphyletic Mosasaurus lemonnieri assemblage from the Craie phosphatée de ciply, Belgium

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 ...

Msx2 in ameloblast cell fate and activity

Frontiers in Physiology, 2015
While many effectors have been identified in enamel matrix and cells via genetic studies, physiological networks underlying their expression levels and thus the natural spectrum of enamel thickness and degree of mineralization are now just emerging ...

Molecular Mechanisms of Dental Enamel Formation [PDF]

Critical Reviews in Oral Biology & Medicine, 1995
Tooth enamel is a unique mineralized tissue in that it is acellular, is more highly mineralized, and is comprised of individual crystallites that are larger and more oriented than other mineralized tissues. Dental enamel forms by matrix- mediated biomineralization. Enamel crystallites precipitate from a supersaturated solution within a well-delineated
