Study Notes
Root Canal Obturation
- Root canal obturation is the three-dimensional filling of the entire root canal system as close to the cemento-dentinal junction as possible.
- The objective is to prevent percolation of periapical exudate into the root canal space and re-infection.
Importance of Obturation
- To stop coronal leakage by establishing a barrier to the passage of microorganisms from the oral cavity to the peri-radicular tissues.
- To entomb and isolate surviving microorganisms that may survive the cleaning and shaping procedure by using an antibacterial sealer.
- To reduce the risk of bacterial movement and fluid percolation into the canal system from gingival sulcus or periodontal pockets and periapical areas.
When to Obturate the Canal
- The tooth is asymptomatic.
- Canals are dry and there is no excessive exudate or healing sinus tract.
- There is an absence of foul odor and a negative culture.
Extension of Root Canal Filling
- The anatomic limit of the pulp space is the dentino-cementum junction (DCJ) apically and the pulp chamber coronally.
- Canals filled to the apical DCJ are filled to the apical limit of the canal.
- Overfilling, underfilling, overextension, and underextension can occur if the filling material is not controlled accurately.
Objectives of Canal Obturation
- To achieve total obliteration of the canal space.
- To eliminate all avenues of leakage from the oral cavity or the periradicular tissues into the root canal system.
- To attain a three-dimensional fluid-impervious seal apically, laterally, and coronally within the confines of the root canal system.
- To achieve a radiographic appearance of a dense three-dimensional filling that extends as close as possible to the cemento-dentinal junction without gross overextension or underfilling.
