This is one of the courses provided by the Department of Oral Medicine and Surgery for undergraduate 2nd year students in the Bachelor Degree in the Science of Dentistry during the second semester. The course has two components, lectures and corresponding practical training in laboratories. The lecture topics cover detailed dental macroscopic anatomy and the basic principles of dental occlusion. Each lecture covers one class of permanent teeth and there is a separate lecture for deciduous teeth. The first two lectures present the dental notation systems and chronology of development and the last lectures introduce the fundamentals of dental occlusion. The practical sessions focus on developing the skills of carving different teeth out of wax blocks. This practice is assumed to help students recalling the details of tooth morphology and improving their manual skills. The latter is significant to have been developed before upgrading to 3rd year. The sessions also include practicing on dental notation, dental age estimation, occlusion as well as skills of tooth identification. By the completion of the practical sessions, each student has to hand in for assessment the laboratory book containing the completed duties that they have been asked to execute.

Theoretical exams, practical exams and practical duties
Attendance: Students must attend 100% of all scheduled classes and labs. Class participation is required. Should an absence be necessary, student should contact the course instructor by e-mail immediately. Work missed can ONLY 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: Practical training will take place in Biochemistry Lab. (M4-L2) on Mondays and Wednesdays. Students are divided into 4 practical sections according to the following table:
8 – 12 pm
M4 – L2
12 – 4 pm
8 – 12 pm
12 – 4 pm
Each student will be allocated a lab code consisting of 4 digits. From left to right, the first digit stands for the section (1,2,3,4), the second and third digits are the bench number (group). The last digit stands for the order of the student on the bench. Students are instructed to recall their lab codes until the practical part is completed because the lab codes will act as their lab. IDs.
During the practical training, students of a given section will be divided into groups, each group will be occupying a pre-determined bench in the lab. and instructed to remain at the allocated location to carry out the practical duties for the full duration of the course. It is important to know that students are not allowed to switch groups, laboratories or sections in the practical part of this course.
At the beginning of each practical session, students will be introduced to the practical duties that they have to carry out on that day. This is followed by a detailed demonstration on casts, radiographs, tooth models and natural teeth under a live camera connected to monitors. In some weeks, short video clips on tooth carving and morphology of the tooth of the week will be run and watched through a monitor. Once introduction and demonstration are finished, student should commence their practical duties under supervision that may include:
Tracing radiographs and assigning teeth to their suitable notation in different notation systems
Tracing radiographs and estimating dental age
Sketching tooth models, jaw models and occlusion curves
Carving teeth out of wax blocks
Answering given questions / quizzes
Making comments after video clip watching.
Preparing and presenting posters illustrating certain topics (optional)
Tools and materials needed for the practical component:
A mechanical pencil, an eraser and a ruler together with the Practical Book. The Practical Book should have alternating blank and lined A4 sheets
A magnifying lens (optional)
A graph-paper book with pre-sketched outlines of all aspects of permanent teeth. The book is available at Alfajr bookshop
A blank graph-paper book for sketching outlines of teeth aspects with additional sheets for helping in tooth carving. The book is available at Alfajr bookshop
Paper adhesive tape, soft tooth brush, retractable blade ((مشرط and pair of scissors
Le Crone carver and a wax knife
12 colored wax carving blocks (the extra ones will be available in case the main ones have failed)
Natural and plastic teeth (it is advisable that students start collecting natural teeth at the beginning of the course) to be used as reference for anatomy and carving and for tooth identification. These teeth / models will also be utilized in practical courses of third year. These are never a waste!
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 instructors on their private mobile phones is prohibited and will unintentionally ruin the lecturer-student relationship.
