COURSE DESCRIPTION:
153 DDS is a one-year course. It is given as a one hour lecture inthe first semester 
and one lecture and one practical session in the second semester of the same year. 
Oral Biology course comprises instructionsin the principles of oral anatomy and 
embryology, oral histology, and oral physiology. 
COURSE OBJECTIVES: 
At the end of the course the student should be able to: 
1. Understand fairly well the principles of the formation and development of 
normal orofacial tissues. 
2. Describe satisfactorily the interrelationship between macroscopic, microscopic 
structures and functions of the oral tissues. 
3. Know correctly the chemical composition of enamel, dentin, cementum, bone 
and the major similarities/differences among them. 
4. Have a fair knowledge of the roles ofsome minerals and factors which affect 
the metabolism of mineralized tissues (bone, teeth). 
5. Have a clear understanding of the biology of the periodontium. 
6. Describe satisfactorily the anatomy of salivary glands and the physiology of 
salivary secretion. 
7. Understand well the principles of occlusal function and articulation as 
determined by craniomandibular relationship.
