DOH100 Lecture Notes - Lecture 2: Glossary Of Dentistry, Neural Crest, Enamel Organ
Document Summary
Ameloblasts flattened as they have no function, only to protect the formed mature. They remain columnar at some fissure sites. Amorphous protein layer that forms and separates cells from enamel. Basal lamina reappears (end of secretion and maturation) Enamel organ layers merge with enamel cuticle to make the reduced enamel epithelium that protects enamel surface. Stratum intermedium and eee and ameloblasts and sr all these cells merge with the enamel cuticle (layer black thing) at the surface. Mature - white (space - fully mineralised) Enamel cuticle above the enamel - those cells are the cells part of the enamel organ - thus enamel formation is an ending process as these cells are now functionless and just protect the enamel. Response to and treatment of pulp injuries. Dentine formation continues because those cells are still there at the periphery of the dental pulp (odontoblasts) and it is called secondary dentine. Tertiary dentine forms in relation to trauma.
