Introduction to Clinical Endodontics

Natasha Flake and Avina Paranjpe

4 Credits / Quarter 7 (Spring, Second Year)

Course Description

Lecture component covers the biology, pathology, diagnosis, treatment, and outcome of dentin-pulp complex and pulpal-related periradicular pathology. Preclinical laboratory component covers endodontic treatment techniques on extracted and artificial teeth from different tooth groups as practice for clinical cases.

Educational Objectives

At the completion of the course, the student should: (1) have an understanding of the biology, pathology, diagnosis, treatment, and outcome of dentin-pulp complex and pulpal-related periradicular pathology; (2) be able to describe the usual anatomic variations in canal and root anatomy encountered in anterior and posterior teeth, and to prepare an appropriate endodontic access preparation in these teeth; (3) be able to state the degree and direction of curvature in a given root canal, to specify the size of the apical foramen, list the specific type, size and sequence of instruments needed to instrument the canal, and then to complete canal instrumentation using either an all hand filing or a combined rotary/hand crown-down technique; (4) be able to specify the adequacy of a root canal preparation, state the final size of the apical foramen, and place a dentin or calcium hydroxide plug if needed; select and test an appropriate spreader for lateral condensation; select, adapt, and evaluate a primary filling cone; mix and evaluate root canal sealer, then complete root canal obturation of given canals; (5) be able to describe and complete proper root canal irrigation, describe and demonstrate aseptic transfer and use of endodontic instruments, and describe and carry out the medication and temporization of a tooth being endodontically treated.

Competencies Addressed

  • UWSOD Competency 1: Examine a patient using contemporary diagnostic methods to evaluate the head and neck region and to reach a diagnosis of the patient’s oral and craniofacial health status.
  • UWSOD Competency 3: Formulate a comprehensive treatment plan based on diagnostic findings, then implement treatment in a safe, properly sequenced and timely manner.
  • UWSOD Competency 5: Recognize the limits of their expertise and seek consultation with other health care providers to facilitate patient care.
  • UWSOD Competency 7: Manage pulpal and periradicular disease.
  • UWSOD Competency 8: Manage dental emergencies.
  • UWSOD Competency 14: Manage periodontal diseases.

Course Expectations

To successfully meet the requirements of this course, the student is expected to attend lectures and laboratories and demonstrate her/his knowledge of the lecture topics and reading assignments through four unannounced quizzes and a final comprehensive written exam. The student must also demonstrate their technical skills through five assigned exercises and a final practical competency examination, each of which must be completed at a passing level. A minimum of 75% of the combined point total of laboratory exercises, quizzes, and final written and practical examinations is required to pass the course.

Effective Winter Quarter 2007, completion of on-line course evaluation is a requirement of this course. Failure to comply will result in an “Incomplete” grade being assigned.
