The dental pulp is located in the pulp chamber with it’s associated canals and forms the middle of the tooth. The dental pulp is composed of soft connective tissue, blood and lymph vessels, nerves and cells.
A pulpotomy is performed when the tooth has become infected and decay extends far enough into the tooth. Bacteria can enter the pulp chamber causing pulp inflammation. The pulp can also be exposed through dental trauma. Where this tooth is indicated for retention and restoration, it is important to remove the bacteria by removing the inflamed infected part of the pulp. A pulpotomy can be performed on both primary and secondary teeth.
A pulpotomy by definition is partial removal of the pulpal tissue, generally the tissue in the pulp chamber leaving healthy tissue in the roots canals. A dressing is then placed over the remaining pulpal tissue and the tooth is then restored, usually a crown is indicated for the treated tooth.
A pulpotomy is a very common procedure in paediatric dentistry due to the large pulp size in primary teeth. When an accurate diagnosis is possible and the pulptomy performed effectively, the tooth will have a good prognosis and the tooth goes on to exfoliate naturally. In the event a pulpotomy is unsuccessful, the infected primary tooth will need to be re-treated with a pulpectomy or extracted. A permanent tooth will be indicated for a root canal treatment.
