ROOT CANAL THERAPY ( RCT )

In the past, injured or diseased teeth frequently indicated for extraction but now the trend has been changed. As dentists became increasingly aware that natural teeth function more efficiently than any replacement, they found it worth additional effort to retain pulpally involved teeth. Although many factors are responsible, the most important reason behind this growth is the extremely high predictability of endodontic success. Recent studies indicate that 95% success is obtainable in endodontics. Despite their recent popularity, implants do not approach this percentage.

What is root canal therapy?
RCT involves the removal of pulpal remnants, and cleaning and obturation of the resultant space, in order to prevent bacterial proliferation with in the canal system.

When not to do root canal therapy?

• Inability of the dentist
• Nonrestorable tooth
• Insufficient periodontal support
• Massive resorption
• Vertical root fractures
• Canal instrumentation not practical
• Non strategic tooth
• Patient unable to afford fee

When to do root canal therapy?

• Pulp irreversibly damaged and/or evidence of periapical disease
• Crown of tooth requires extensive modification,e.g. overdenture

What is root canal procedure?
Once root canal therapy is indicated, the concerned area is administered with local anesthesia, once area is numb. Then the opening is made in the crown of the tooth and root canals are cleaned and shaped, they are filled with rubber like material called gutta-percha. After completion of root canal therapy crown is placed so as to restore the tooth to full function.

“The tooth, when properly treated and restored, can be retained as long as any other tooth”.
