Course Description
This is one of the courses provided by the Department of Oral Medicine and Surgery for undergraduate 2ndyear students in the Bachelor Degree in the Science of Dentistry during the second semester. The course has two components: lectures and practical training. The lecture topics cover in-depth the whole field of Oral and Maxillofacial Histology and Embryology. This includes the different stages of odontogenesis, details of tooth structure and its supporting tissues as well as discussion of oral tissues and adjoining structures. The first two lectures review the relevant orofacial embryology, which is significant for understanding the development of teeth and oral tissues. During each practical session, students examine the tissues covered in the corresponding lecture under instructor supervision. This is done by presenting slides on data projector in a similar way as if they are viewed under a microscope.

Course Objectives / Weights
  1. To learn how the jaws, face and oral structures develop and interact during embryogenesis.
  2. To acquire the comprehensive knowledge related to the different stages of tooth development including development of enamel, dentine-pulp system and periodontium.
  3. To recognize the role of deciduous teeth and their structures in the development of permanent teeth.
  4. To recognize the importance of reciprocal tissue interaction in tooth development.
  5. To study the structure of dental, oral and relevant extraoral tissues in-depth.
  6. To identify the significance of studying oral and maxillofacial histology for clinical dental practice.
  7. To recognize how learning normal tissue structures is important formicro- and macroscopic identification of abnormal pathological conditions.

Additional Notes
Attendance:
Students must attend 100% of all scheduled classes and labs. Class participation is required. Should anabsence be necessary, student should contact the course instructor by e-mail immediately. Work missed canONLY make up with an excused absence.
  • No make-up exams or quizzes will be given for unexcused absences
  • Late arrivals to class are unexcused absences
  • All course make-ups, test, and so forth, must be completed within 14 days from the date of the excused absence.
Practical component:
In each practical session, electronic slides related to the topics covered in the previous lecture will be presented on a data projector. The program installed on the instructor’s computer allows for high power magnification and displaying of fine details at cellular level as if they are viewed under slide microscopic examination. Presentation involves inter-active communication between the instructor and the students. Following presenting each slide, students will be given some time to report the duties accomplished. This includes:
  • Sketching, labeling and describing the slides presented
  • Identifying all the required histological features and their functions
  • Noticing how the same feature looks different on varying sections / slides
  • Answering question asked by the instructor
Each student has to bring a pencil, an eraser and a ruler together with the Practical Book. The Practical Book should have consecutive blank and lined A4 sheets for sketching and describing slides as well as answering questions.
Student instructor relationship:
  • Students are instructed to frequently access the uploaded handouts, recourses and extra learning materials on the e-learning link on the University's website.
  • e-learning will also allow for mentor-student interaction through online evaluation in the form of tutorials, assignments and quizzes.
  • Students will be able to view the outcomes of their evaluation uploaded on e-learning. This includes the results the quizzes and the midterm practical exams.
  • It is strongly recommended that the instructor is contacted either personally in his office within the frames of the office hours provided or through email / e-learning. Contacting the instructor on his private mobile phones is prohibited and will unintentionally ruin the lecturer-student relationship.
