Intro to endodontics

  2. 2. DEFINITION: Branch of dentistry concerned with the Morphology Physiology and Pathology of the human dental pulp and periradicular tissues.
  3. 3. Its study and practice encompass the basic and clinical sciences including  biology of the normal pulp  the etiology  diagnoses  prevention  treatment of diseases and injuries of the pulp and associated periradicular tissues.
  4. 4. Principles of endodontic therapy  Diagnosis  Patient education  Local anaesthesia  Isolation – Rubber dam isolation  Access cavity  Working length  Instrumentation  Obturation  Final restoration
  5. 5. Diagnosis: According to Ingle, diagnosis is the procedure of  accepting a patient  recognizing that he has a problem  determining the cause of the problem and  developing a treatment plan that will solve or alleviate the problem
  6. 6. Chief complaint History [ Medical/Dental] Objective examination Subjective examination Radiographs Diagnosis
  7. 7. Patient education: Patient should be informed about the condition of his teeth and the treatment options available Instructions to the patient about improvement of the oral hygiene
  8. 8. Local Anaesthesia: Similar to the local anaesthesia given for various other dental procedures. Supplemental anaesthesia may be required for certain cases – "HOT TOOTH"
  9. 9. Isolation: Rubber Dam isolation - usually a single tooth isolation Isolation is very important not only for maintaining a sterile field but also to prevent Aspiration of irrigation materials and instruments
  10. 10. Access cavity
  11. 11. Working length
  12. 12. Instrumentation:
  13. 13. Obturation
  14. 14. Final Restoration:
  15. 15. Indications & Contraindications Indications:  Carious teeth [caries involving pulp] • teeth with irreversible pulpitis • necrotic pulps  treatable periodontal conditions [endo-perio lesions]  salvageable resorptive defects  Supra-erupted teeth with good bone support  Fractured teeth involving pulp  Intentional endodontics for FPD's or overdentures
  16. 16. Contraindications: •Insufficient periodontal support •Canal instrumentation not Practical  calcification of the canal  Sharp dilaceration/curvature of the roots
  17. 17. • Non restorable teeth
  18. 18. Inadequate crown root ratio Vertical tooth/root fracture
  19. 19. Patient's general medical condition Patients general medical condition is never an absolute contraindication to endodontic therapy
  20. 20. Considerations prior to endodontic therapy • Is the tooth needed or important? Does it have an opponent? Could it some day serve as an abutment for prosthesis? • Is the tooth salvageable, or is it so badly destroyed that it cannot be restored? • Is the entire dentition so completely broken down that it would be virtually impossible to restore? • Is the tooth serving esthetically, or would the patient be better served by its extraction and a more cosmetic replacement?
  21. 21. • Is the tooth so severely involved periodontally that it would be lost soon for this reason?
