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.
