Course Requirements and Grading:

The primary objective of the division of Endodontics is to contribute to the total college efforts in preparing the students to become excellent clinical practitioners. In order to carry out this goal, clinical (5th year) Endodontic students will be evaluated by his/her performance on:

Student evaluation:

Student performance in the course will be evaluated as follow:

|Continuous Assessment |Final Examination |

| |Marks | |Marks |

| |10 | |80 |

|2 module Exams |10 |Written Exam |20 |

|2 module Exams |20 |Oral Exam |20 |

|Midyear Exam |40 |Practical Exam. | |

|Clinical Requirements | | | |

|T O T A L |80 |T O T A L |120 |

Clinic Grading Cards

The endodontic sheet form will only be utilized to record the student’s activity in clinic. The student should make appropriate diagnosis, entries for tooth, working length determination, cleaning and shaping of root canal (s) using step back instrumentation technique, root canal obturation technique using lateral gutta-percha obturation technique. All procedure grades will be recorded on the “Endodontic Clinical Evaluation Card”. The evaluation letter (‘A*, A , B*, B, C*, C- ,D*,D and E which is unacceptable) will be marked by the faculty staff. Evaluation form for every student is available with instructor every clinical session. The endodontic sheet for the clinical finished cases of student will be collected by the instructor, submitted to course director and kept in the Endodontic office.

2 module exams:

Written first quiz will performed at the end of each lectures module, covering all the teaching materials up to this time. The question will be in form of MCQ, definitions or complete.

Midyear Exam:

Written midyear exam will performed at the end of the first term, covering all the teaching materials up to this time. The question will be in form of MCQ, definitions or complete, and assay.

2 module exams:

Written second quiz will performed at the end of each lectures module of the second term covering all the teaching materials up to this time. The question will be in form of MCQ, definitions or complete.

Final Exam:

o Final (Written) Exam

The Final Exam will cover all materials in the course.  Test questions on the first quiz, Midyear, second quiz and Final examination will come from information found in the Lecture Outlines, Supplemental Reading List, Lecture Presentations, and any other handouts provided during the progression of the course.

o Data show Exam

After the written exam, the students will be examined orally in the covering material during course. The exam will be performed in form of station, managing problem or other material discussed in the previous course using slide data show to keep the standardization of evaluation between student (males and females).

Evaluation of final

The final course grade will be determined by sum of the numerical grades of clinical requirement, first quiz, midyear exam, second quiz and Final Examinations.

Grading Scale:

85 to 100 = A 65 to  74 =   C

75 to  84 =   B 64 to 60 = D Below 60 =   F

Grading policy:

Attendance:

Attendance is mandatory for all lectures and clinical sessions. Exceeding the maximum permissible absences might lead to your deprivement from attending the final exams. Unexcused absences from written exams will result in marks being deducted from your final grade.

Deadline for requirements completion:

The deadline for completing the clinical requirements is the last day of the course as published by the Office of the Associate Dean for Education. Failure to complete the class assignments by the specified deadlines will result in reduction in the clinical requirement's marks relative to the number of the deficient requirement, which will undoubtedly affects the final overall student score.

Expectations from the students

2 - CLINICAL PROTOCOL

1. The clinic timings will be 3 hours only.

2. The student should attempt to treat single canaled teeth first then move on two or three canaled teeth.

3. If a single canaled tooth is not available, the student can initiate a two canaled bicuspid or molar.

4. The molar tooth should be initiated when the student has at least performed root canal therapy on two root canals.

5. If a two canaled bicuspids is not available the student can replace it with two single canaled bicuspids or anterior teeth.

6. The cases selected for treatment should be of routine nature and the students should discuss the case with instructors prior to initiating endodontic therapy.

7. It is the responsibility of the student to coordinate with the booking area regarding appointments for patients.

8. Case started with one instructor should be preferably completed under the supervision of same instructor.

9. The student start his/her treatment with taking chief complains, performing subjective and objective examination of the case.

10. The supervisor should discus and accepts the diagnosis of the case.

11. Strict aseptic technique will be followed in clinic and use of rubber dam will be mandatory.

12. It is important to have the endodontic therapy records properly filled out, signed and evaluated by the instructors in the endodontic sheet.

13. The radiographs belonging to each case should be properly arranged on mounts available at radiology. The radiographs and patient records should be handed over to instructors at the earliest opportunity. Each student must fulfill all endodontic steps of assigned teeth to the satisfaction of the instructor.

• It is required that each student submits the finished endodontically treated teeth with the radiographs including five radiographs as follows:

1. Pre-operative radiograph

2. Working length determination radiograph

3. Master apical file radiograph

4. Intermediate radiograph (i.e.) a radiograph after cementation of the master cone and two accessory cones.

o Or radiograph of properly selected master cone

5. Post operative radiograph (i.e.) a radiograph after cutting the excess gutta percha, cleaning the access, removal of the clamp, the rubber dam and placement of temporary filling.

• Each step should be evaluated and signed by supervisor in the endodontic sheet.

• All the radiographs and the signed sheet of the test case should be submitted to the division at the end of the clinical session.

• Satisfactory completion of the clinical course is based on the following criteria:

1. Each student must follow accepted endodontic principles in treating the case from pre-operative examination selection of the case until filling of the root canal.

2. Each student is required to follow radiographic method in length determination.

3. Each student is required to follow the step-back technique in preparing the root canal system except in some cases step-down technique will be used.

4. Each student is required to follow cold compaction technique to obturate of root canal system.

5. In addition, each student must demonstrate his/her knowledge of the principles of radiography as applied to endodontic therapy by obtaining adequate radiographs at various stages during the endodontic procedures.

Quick Guidelines for Treatment of an Endodontic Case

1. First appointment:

a. Review and update medical history – take medical history if not previously taken.

b. Question patient as to area of problem (chief complaint) and what type of symptoms patient is having. All has to be documented on the Endo therapy record.

c. Take preoperative film of suspected area if you don’t have a recent film. Review preoperative film for periapical changes, tooth morphology, pulpal morphology, caries or restorations impinging on pulp, etc.

d. Perform necessary diagnostic tests:

i. Sensitivity tests both electric pulp tester (EPT) and thermal “ICE” whenever are applicable to determine the condition of the pulp.

ii. Percussion and palpation to check the periapical.

iii. Test cavity in case of full coverage.

iv. Anesthesia test in case of diffuse pain.

v. Fistulous tracking test in case of sinus tract opening.

If information is sufficient, arrive at a diagnosis as to which pulp is involved and what treatment is necessary.

e. If endodontic treatment is required, explain to the patient what you are going to do and why it is necessary.

f. Anesthetize the tooth. After you disinfect the tooth and the area.

g. Isolate involved tooth with rubber dam (only tooth being treated needs to be isolated). Check with your instructor in case rubber dam cannot be placed.

h. Prepare access opening and refine it so each canal be entered. Debride pulp chamber. Irrigate with sodium hypochlorite. Use other solution if rubber dam is leaking.

i. Determine the working length of the canal.

j. Instrument the canal to the working length at least to the size that removes most of the pulpal tissues. During instrumentation, irrigate frequently with hypochlorite if the canal is difficult to negotiate, discuss with your instructor. After instrumentation, irrigate and dry canal.

k. Place a cotton pellet in chamber and close access opening with cavit (cotton pellet should be blotted almost dry before placement). Consult with your instructor the best type of medication in your case if its indicated.

2. Second appointment:

a. Anesthetize the tooth

b. Isolate the tooth with rubber dam

c. Remove the temporary and the cotton pellet

d. If the tooth is asymptomatic and no drainage present in the canal do the following:

i. Complete instrumentation

ii. Irrigate with NaOCl

iii. Dry canal with paper point

iv. Fit the master cone and two accessory cones using cold compaction technique and radiograph the tooth.

v. Complete canal filling procedure

vi. Remove excess filling material

vii. Place permanent or temporary filling material

viii. Remove the rubber dam, the clamp, put temporary filling and take final radiograph

e. If the tooth is symptomatic and / or drainage is present in the canal(s), do the following:

i. Irrigate the canal

ii. Re-debride the canal and complete instrumentation

iii. Dry the canal

iv. Place Ca(OH)2 , cotton pellet and temporary filling.

NOTE:

These four steps may have to be done for several appointments until tooth is asymptomatic and no definite drainage is occurring into the canal(s), or Ca (OH)2 can be used in such cases.

3. Third appointment:

a. Anesthetize the tooth

b. Isolate the tooth with rubber dam

c. Remove the cavity and the cotton pellet

d. If the tooth is asymptomatic and no drainage is present in the canal, fill it as outlined in the second appointment step (d).

Always consult with your instructor before dismissing the patient.

Assessment Guidelines

Prior to taking the approval of competency examination:

1. The student must attain of an at least 80% in attendance sheet of both lectures and clinical session.

2. The student must fulfill of at least 60% of clinical requirements with satisfactory evaluated score

Instructor Reflection

Instructor Reflection on the course:

The current course fulfills what the student need to know at this stage of education. The course enables the student to acquire recognition skill to diagnose and treat the pulpally and periradicularaly involved teeth with the least iatrogenic errors.

Strength Points:

1. It is fully applied course

2. Experienced teachers

3. Adequate teaching facilities

4. The clinical explanation and demonstration is performed by professors and lecturers of department even the clinical demonstration (highly qualified staff) not by genior members (demonstrators). This will allow the student at the end of course , be able to manage and treat every simple and complicated endodontic involved cases either with single rooted or multirooted teeth with satisfactory result

5. The student is allowed to treat sufficient number of clinical cases so that he/she will get sufficient experience to manage the CC cases in the next year..

6. Every two year, the course subjects redistributed over the staff allow the enhancement and development of the teaching

7. The student start to use the rotary systems for cleaning and shaping of the root canal system of some clinical cases

8. The student start to use the portable X-ray machine which facilitate radiography in the clinical sessions

Weak Points:

1. Insufficient number of demonstrators comparable with increasing the number of the students every year.

2. Shortage of x-ray devices inside the clinical section lead to waste time during clinical procedures

3. Lack of qualified radiographer technician lead to several remake of x-ray film by student, increasing the waste time and the hazard of radiation

4. shortage of EAL`s in the clinical area

5. portable X-ray units are not enough compared with large number of students

Innovation and plan for future:

1. Each student successfully use the rotary root canal files for treatment of all clinical cases

2. Each student learn to use the digital radiographs

3. Up to date course every year

4. e-teaching

5. E- sheet marking for evaluation of the studen
