Study Notes
Endodontics
- Endodontics is the branch of Dentistry that deals with the etiology, prevention, diagnosis, treatment, and prognosis of diseases of the pulp and periapical tissues.
Objectives of Endodontics
- The objective of endodontic therapy is to restore the treated tooth to its proper form and function in the masticatory apparatus in a healthy state.
Scope of Endodontics
- Differential diagnosis of oral pain of pulpal and/or periradicular origin
- Vital pulp therapy
- Nonsurgical treatment of root canal systems of pulpal origin
- Obturation of root canal systems
- Endodontic Surgery
- Retreatment of teeth previously treated endodontically
- Treatment procedures related to coronal restorations by means of post and/or cores involving the root canal space.
Endodontic Course Outline
- Morphology and Access Cavity
- Endodontic Instruments
- Cleaning and Shaping
- Root Canal Obturation
Pulp Space Morphology
- Components of root canal system
- Classifications of Root Canal System (Classes and Types)
- Pulp space Morphology of Different teeth
- Principles of Coronal Access Cavity Preparation
- Errors during endodontic cavity preparation
- Problem solving in endodontic cavity preparation.
Components of the Root Canal System
- Pulp Chamber: The portion of the pulp within the crown
- Root Canal: The portion of the pulp within the root
- Apical foramen: an aperture at or near the apex of the root
Morphological Features of the Pulp Cavity
- Roof of pulp chamber
- Wall of pulp chamber
- Floor of pulp chamber
- Size of the pulp chamber decreases by age and irritation of the pulp.
Pulp Horns
- Accessory canal: any branch of the main pulp canal or chamber that communicates with the external surface of the root
- Lateral canal: an accessory canal located in the coronal or middle third of the root
- Furcation canal
Apical Root Anatomy
- Apical Constriction (Minor Diameter): the narrowest diameter short of apical foramina or radiographic apex
- Apical Foramen (Major Diameter): the main apical opening on the surface of root canal through which blood vessels enter the canal
- Isthmus: a narrow, ribbon-shaped communication between two root canals that contains pulp or pulpally derived tissue.
Classifications of Root Canal System
- Weine Classified root canal anatomy into six types
- Type I: A single canal extends from the pulp chamber to the apex
- Type II: Two separate canals leave the pulp chamber and join short of the apex to form one canal
- Type III: One canal leaves the pulp chamber and divides into two then merge to exit as one canal
- Type IV: Two separate distinct canals extend from the pulp chamber to the apex
- Vertucci Classification
- Type I: Two or three canals with no communications
- Type II: Two canals with a definite connection between them
- Type III: Three canals with a definite connection between them
- Type IV: Canals extend into the isthmus area
- Type V: A true connection or corridor throughout the section
