Age and functional changes In Enamel

Age and functional changes In Enamel Enamel is a non-vital tissue and is not capable of regeneration. 1-    Attrition It is the physiological wearing away of the tooth hard substance. It is mainly encountered in the occlusal and incisal surfaces. Proximal attrition may occur due to the slight mobility of the teeth during mastication. Attrition occurs […]

2 Comments on Amelogenesis 2

Amelogenesis 1 Amelogenesis 2 Two processes are involved in the development of enamel. Organic matrix secretion. Mineralization and Maturation. 1- Organic matrix secretion The ameloblasts begin their secretory activity shortly after dentin formation is initiated. Synthesis of enamel protein occurs in the rough endoplasmic reticulum, from where it is passed to Golgi complex in which […]

Amelogenesis 2 Amelogenesis 1 The cells forming enamel, the ameloblasts differentiate from the inner enamel epithelium. Ameloblasts begin enamel deposition after a few micrometers of dentin have been deposited. Dentinogenesis begins at the late bell stage of tooth development. Shortly thereafter, amelogenesis begins. The life cycle of the ameloblasts In the early development, the inner dental epithelium […]

No Comments on Structure of Enamel

Structure of Enamel.   Enamel is essentially a tightly packed mass of apatite crystals and most of its structural features are the result of a highly organized pattern of crystal orientation. Enamel is retained in ground sections and can be studied with the light microscope by means of transmitted light.   Structure of enamel is: […]

Enamel   Enamel is the hardest calcified tissue in human body. It forms a protective covering of the entire crown surface. Enamel is unique because it is a mineralized epithelial tissue, while bone, dentin and cementum are mineralized connective tissue. Mature enamel is the only tissue that is totally acellular. It is also avascular and […]
