PRINCIPLES OF OPERATIVE DENTISTRY
Course Director : Dr. Mohammed Quaid Al-Qahtani [ DUC ]
Preclinical Operative Dentistry
COURSE GOALS AND OBJECTIVE
1. The primary objectives of this course is to present the basic principles, techniques
and rational of operative procedures and apply them.
2. Present a step-by-step procedure for each cavity preparation and cavity restoration.
3. Train the students in different operations (cavity preparation and restoration) by
doing specific standardized exercises on Typodont Models mounted on mannequins.
4. Train the students in these operations in a situation similar to the clinical set-up.
5. Train students to recognize their own mistakes, and how to correct them.
6. By the end of this course, the student must be prepared to take the next
ORGANIZATION OF THE COURSE
There are two basic components to this course: class lectures and lab
I. CLASS LECTURES
Most of the knowledge that you will be required to learn will be presented
through a variety of formal lectures.
These will be structured to help you understand the reasons behind the
procedures that you will be using as well as teach you the basic knowledge
you will need to perform the procedures.
- Once a week, the lecture period will begin with a quiz on the previous week's lecture
The Final Quiz grade will be determined by averaging the weekly quizzes, grades,
including zero for those quizzes not turned in.
There will also be a mid-term and final examinations.
These exams are also geared to the course objectives and are designed to determine
how well you have learned the material and how you are progressing toward
achievement of the objectives.
All of these testing procedures form the base for your grade in operative dentistry
and are weighted accordingly to their importance.

- Pickard manual

approach, 2nd edition 2001.
- Hand-outs (if needed)
II. LAB EXERCISES
The laboratory phase of the course is a very important component of your
training in Operative Dentistry.
Practice exercises will help you develop skills in Operative Dentistry procedures.
All of the tasks that will be practice in the laboratory must be performed
according to specific criteria taught during lectures.
Each exercise is turned in first for evaluation and finally for grading to the
appropriate group instructor.
As you practice each of the tasks assigned in the laboratory, you will
increase your skills and more well on your way to developing competency.
Unacceptable projects must be remediated to an acceptable level by the
way of repetition or further exercises assigned by the Course Director.
- INDEPENDENT TIMED-EXERCISES
After considerable practice, each student will be tested on the
performance of a sequence of procedure. They will be 6 practical
Lecture and Lab
95 - 100 = A+
90 - 94 = A
85 – 89 = B+
80 - 84 = B
75 - 79 = C+
70 - 74 = C
65 - 69 = D+
60 - 64 = D
Below 60 = F
The student has to achieve a passing grade in both the Didactic and Laboratory
Sections of the course to be eligible for promotion.
1. Assessment both in theory and practical
The grading in the assessment of theory and practical is divided into
the following system.
• Quizzes : 10%
• Mid-Year exam : 15%
• Daily projects : 10%
• Practical exams : 20%
• Subjective Evaluation : 5%
Total ---------------------------- 60%
2. Final examination
Final examination is computed as follows:
• Final written : 25%
• Final practical : 15%
- All preparations and restorations listed on the progress sheet will be
approved and graded by the designed instructor.
- All timed practical exercises will be completed during assigned laboratory
- Written examinations will be based on the LECTURE MATERIAL; HANDOUTS,
READING ASSIGNMENT, PRINT-OUT and information given
during lab sessions.
GRADING CRITERIA STATEMENT
The following criteria will be used in evaluating student lab work:
1) ATTENDANCE: All students are expected to be in the lab during those
times designated for unit laboratory.
a. Attendance will be taken during the sessions.
b. Completion of all projects is a requirement for oral and lab exams.
2) PREPARATION CRITERIA: Each exercise is turned in at a fixed time, corrected
by enumerating the mistakes. The student is then asked to correct the mistakes or to
do it over.
3) The following will be considered as a basis for a FAILURE:
a. Adjacent teeth damaged during preparation.
b. Examination tooth or any adjacent teeth removed during the preparation.
c. Over-preparation and under-preparation of teeth which would result in :
i. Inability of the preparation to be restored effectively with the
material for which the preparation was intended.
ii. Any damage to the tooth which, in actual clinical practice, would
result in the necessity to perform root canal treatment or surgical
removal of the tooth.
d. Preparation partly or entirely done by any individual other than the
student who is submitting the work.
Criteria based on Point System
*Unacceptable = redo
Below average = less than desirable
Acceptable = improvement recommended
Above average = needs minor correction
Excellent = maintain this level of performance
* Exercise to be repeated for re-evaluation.
- Project may be done, if missed during one's own time with genuine
- Examination may be re-taken with genuine excuse and permission from
Administration (Dean or Vice-Dean).
- These "grades" will be recorded on your individual progress sheets.
- There will be no redo for missed quizzes with excuse and the average
grade will be divided by the number of quizzes minus one.
Class representative, chosen form the class, will be responsible for photocopying
hand-outs and print-outs. There may at times be needed for class purchase which will be
communicated to the class representative in advance.
Students will be required to possess the following during all laboratory session.
a. Disposable gloves (natural teeth)
b. Disposable masks
c. Protection glasses
The following items must be purchased by each student:
2. Extra-fine permanent markers (red, black, green)
*** Students will be required to provide natural teeth for the tooth colored exercises:
- 4 molars (upper or lower)
- 2 Pre-molar (upper or lower)
- 4 anterior (upper or lower)
You will be given precise instructions on mounting these teeth by your group
