Academic Year 1428/1429H. (2007/2008G.)




            This course consists of a didactic and clinical component with four credit hours.  It will cover:


1.         The treatment of different types of periodontal diseases.


2.         The interrelation between periodontics and related dental specialties.


3.         Introduction to the surgical approaches in the management of moderate to advanced periodontal diseases


4.         The role of occlusion in periodontal diseases and management.


5.         The surgical aspect of implant dentistry and management of tissues around implants in health and disease.





            At the end of this course the student should be able to:


1.         Perform a comprehensive diagnosis, discuss prognosis and make treatment plan which includes the specific surgical approaches necessary.


2.         Master the motivation and oral hygiene instruction of patients in addition to subgingival scaling and root planing.


3.         Describe the indication and procedure of specific surgical technique


4.         Understands the objective and different procedures of crown lengthening technique


5.         Under stands the importance of post surgical follow up and wound healing.


6.                  Asses and evaluate the result of the performed therapy and project the long term result.

7.         Be aware of recent advances in periodontics

8.                  Understands the role of trauma from occlusion in the etiology of periodontal disease

9.                  Introduction to implant dentistry from surgical point of view

10.              Develop the necessary knowledge for peri-implant structure and skills for implants maintenance.




This second part will involve the treatment of patients with different types of periodontitis. Upon completion of this part, the student should be able to:


1.         Discuss the etiology, diagnosis, prognosis and treatment planning for different types of  periodontal conditions including the surgical treatment needed.

2.                  Carry out treatment of patients involving routine preventive care and non-surgical periodontal treatment to patients with early and severe form of periodontal disease as well as accurately interpret and evaluate the results of treatment rendered.

3.                  Basic surgical procedures such as gingivectomy, different periodontal flap surgery, crown lengthening procedures.

4.                  New regenerative techniques such as bone regeneration and tissue regeneration will be demonstrated.





            Students must satisfactorily complete the following requirements:


1.         Finish at least six (6) clinical cases:


*          One slight case either gingivitis or periodontitis with slight amount of subgingival calculus or other local factors

*          One generalized periodontitis case with moderate amount of subgingival calculus or other local and systemic factors

*          One generalized periodontitis case with moderate/ sever amount of subgingival calculus or other local and systemic factors

*          One surgical case either as surgical procedure for restorative purpose (e.g crown lengthening) or conventional periodontal surgery (e.g. open debridement or modified Widman flap)

*          One re-evaluation case (student own finished case)

*          One recall and maintenance case (previously treated cases)

*          Any additional case beyond requirement will be considered in your clinical grading as bonus



¯     The student is not allowed to start any case before screening of the case by the course director.


¯     It is not allowed to dismiss or transfer patients from the course to another or from a student to another without the approval of the course director.


¯     One of the completed cases should be selected by the student for the clinical examination and should be approved by the course director.

¯     A student is allowed to start the treatment procedure except after signing and approving  the initial treatment plane  by the faculty supervisor.


¯       Zero (0) mark is given to the student who fails to fulfill the above mentioned items.


2.         It is expected that the student will perform satisfactorily in both the clinical and the written components of the course.


3.         Regular and prompt attendance in the clinic.


4.         Complete and careful record keeping of all assigned patients.


5.                  Completion of the clinical requirements.




            Final mark will be calculated as follows:


A. Written examination (50%):


            1. Midterm examination                      20%

            2. Final examination                            30%                                        


B. Clinical Evaluation (50%)                      


Routine clinical evaluation                  40%

 Clinical competency exam                 10%


                                    TOTAL      -        100%



            Clinical grading will be only in the categories of preparation, professionalism, knowledge and management of the patients.  Evaluation will be done weekly for the student and recorded on the evaluation forms.


The routine evaluation will be done on all patients under the student's care. Any procedure recorded as complete must be evaluated. Scaling and root planing must be evaluated on a quadrant or sextant basis. It is the STUDENT responsibility to assure that his/her work is being regularly evaluated.


Routine evaluation marks will be calculated from the clinical evaluation form which a student should submit it with each case treated and make sure that it is graded by his/her instructor (student’s responsibility).  This evaluation measures the quality of the work performed by the student during the management of his/her periodontal patients.  Marks will be calculated using point system and depends on the case type and procedure as follows:



§         Gingivitis case account                                                     1 point out of 5

§         Slight periodontitis case account                                      1.5 points out of 15

§         Moderate periodontitis case account                                2.5 points out of 15

§         Severe periodontitis case account                                     2.5 points out of 15

§         Re-evaluation after initial therapy of a case account        2.5 points out of 15

§         Recall of a finished case treated by student account       2.5 points out of 15

§         Periodontal surgery or crown lengthening account          2.5 points out of 15


Example:         Student treats a slight periodontitis case (examination, diagnosis, treatment plan and initial therapy) and the calculated average of the case from student evaluation form is 80% then the point for this case is:

                        (80 x 1.5) ¸ 100 = 1.2 out of 1.5 points


Requirement marks:  When a student successfully finish all the requirements than the student will be given the total marks which is 15% of the total marks of the course provided that each requirement case type passed successfully (at least 60% average on the evaluation form) otherwise, if a student finish a case type with less than 60% evaluation it will not be considered toward the requirement.


Clinical oral exam: it includes one of the student case documented by radiographs and complete signed periodontal form with charting clinical examination and treatment plane. In addition, examination of general periodontal knowledge is included. This exam should be performed during the 1st semester.


Clinical scaling and root planning exam: it should be performed in any quadrant of the ingoing treated case with at least moderate amount of subgingival calculus and should be approved by the COURSE DIRECTOR. Examination should not be started before informing both the course director and the supervisor. This exam can be done any time during the 2nd semester TWO weeks BEFORE the end of the semester.


Surgical procedure report: is evaluated on preparation, knowledge and pre-prepared report which includes type of surgery, step-by-step procedure and advantages and disadvantages (type written) of the procedure in addition to pre and post surgical radiographs and photographs. All photographs and radioghraphs should be documented and submitted on a CD with the report two week after surgical performance.


Routine Evaluation and Requirement:


            The final marks account 40% of the total marks of the course and it is distributed as follows:


§         Routine evaluation            25%

§         Requirement                      15%




* Zero (0) mark is given to the student who shows improper management of the case, repeated ignorance to instructions, irreversible damage, improper behavior with patients and/or clinical instructors.


·        Zero (0) mark is given to the student who fails to finish the clinical work during the allotted clinical time per session. If the student got another Zero (0) on another case for the same reason, the case will be canceled. However the student Must continue the treatment of the case.


·        Any clinical procedure that is performed by the student should be recorded in the patient's file. The student should also write clearly her/his name, university number and signature. This should be followed by the signature of the faculty instructor supervising the student at the end of each clinical session.


·        The clinical marks are affected by student's behavior, punctuality, knowledge, time control and her/his personal professional appearance in the clinic.


·        Attendance of students in both lectures and clinic is mandatory. Student absence at any clinical session is absolutely not acceptable. Being 5 minutes late to the lecture or 15 minutes late to the clinical session is considered as absence. This will affect the student's evaluation. However, absence due to emergency and sickness may be accepted when providing a medical report to the course director.


     When 25% of the lecture or the clinical sessions are missed, the student will be deprived from taking the final exam according to the university rules and regulations.


·        Coordination with the Booking Area to bock patients and confirming appointment to the patients are the responsibilityes of the students.
