Dental Histology

Chapter 12 Enamel

What is the most highly calcified dental tissue? Enamel
What is enamel composed of? Calcium Hydroxyapatite
Calcium Hydroxyapatite Ca10(PO4)6(OH)2
Does enamel have blood vessels or nerves? No
Attrition Loss through tooth to tooth contact from mastication with age or parafunctional habits
Erosion Loss through chemical means-such as acid.
Abrasion Loss through friction from tooth brushing or toothpaste.
Caries Cavities. Loss from chemical means-acid; from cariogenic bacteria by way of biofilm.
Abfraction Possible loss through tensile and compressive forces during tooth flexure with parafunctional habits. The pressure can cause cracks or splits in the enamel.
What are some clinical considerations for enamel? Attrition, Erosion, Abrasion, Caries, and Abfraction
What is amelogenesis The process of enamel matrix formation
When does amelogenesis occur? During the apposition stage of tooth development.
What do ameloblasts secret? Enamel matrix from the Tome's procces
When does the enamel organ become an ameloblast? After dentin is deposited in the IEE of the enamel organ.
What is the function of amelobasts? They pump calcium hydroxyapatite into the partial mineralized enamel matrix while trying to take out the organic materials.
REE fuses with the oral epithelium to form? a canal to allow the enamel cusp to erupt through the oral epithelium into the oral cavity.
Packed masses of hydroxyapatite crystals from what? enamel rods or prisms
Function of enamel prisms Help with strength, they run from the DEJ and the outer edge of the enamel surface.
Fluoridation can be supplied what two ways? Systemically through water or supplements or topically through fluoride trays.
What are enamel sealants? protective covering of cavities and fissures.
What is a clinical consideration of whitening trays or strips? They do not produce any structural changes in the dentin tissues but some people are sensitive to the bleach.
