Root Canal Treatment (RCT)

The inner central core of the tooth is known as the pulp of a tooth. The pulp contains nerves, blood vessels, connective tissue and reparative cells. The purpose of pulp therapy in Paediatric Dentistry is to maintain the vitality of the affected tooth so that the tooth is not lost).

The main reasons for a tooth to require pulp therapy are dental caries (cavities) and traumatic injury. Pulp therapy is often referred to as a “nerve treatment”, “children’s root canal”, “pulpectomy” or “pulpotomy”. The two common forms of pulp therapy in children’s teeth are the pulpotomy and pulpectomy.

A pulpotomy removes the diseased pulp tissue within the crown portion of the tooth. Next, an agent is placed to prevent bacterial growth and to calm the remaining nerve tissue. This is followed by a final restoration usually using a stainless steel crown).

A pulpectomy is essential when the entire pulp is involved in the root canal of the tooth. During this treatment, the diseased pulp tissue is completely removed from both the crown and root. The canals are cleansed, disinfected and in the case of primary teeth, filled with a resorbable material. Then a final restoration is placed. A permanent tooth would be filled with a non-resorbing material.
