Oral Histology

Course outcomes:

a. Knowledge and Understanding:

1-	Distinguish the different dental hard tissues.
2-	List different phases of eruption and shedding.
3-	Identify the structure and the function of different dental hard tissues.
4-	State the histological age changes and clinical consideration of dental tissues.

b. Intellectual Skills:

1-	Determine the different dental hard tissues.
2-	Explain any abnormalities that might affect the shedding of deciduous teeth.
3-	Interpret different phases of eruption and shedding.
4-	Conclude the clinical significance associated with certain dental structures.

c. Professional and Practical Skills:

1-	Discover the different dental tissues as well as phases of eruption and shedding through power point data show.
2-	Draw the histological structure of dental tissues
3-	Demonstrate the technical steps for preparation of tooth ground and decalcified microscopic sections as well as the main histological and histochemical stains.
