Pääsyjuurikanava

Pääsyjuurikanava refers to the access pulp chamber in a tooth. This is the space within the crown of a tooth that contains the dental pulp, which is composed of nerves, blood vessels, and connective tissue. When a tooth requires root canal treatment, the first step involves accessing this pulp chamber. This is typically done by a dentist drilling a small opening through the enamel and dentin layers of the tooth to reach the pulp.

The purpose of creating a pääsyjuurikanava is to remove the diseased or infected pulp tissue, clean and shape the root canals, and then fill them to prevent further infection. The location and size of the pääsyjuurikanava can vary depending on the type of tooth and its specific anatomy. For instance, anterior teeth generally have a single root canal, while posterior teeth can have multiple.

Successful endodontic treatment relies heavily on the dentist's ability to effectively locate and prepare the pääsyjuurikanava. This requires precise instrumentation and thorough cleaning to ensure all infected tissue is removed. The integrity of the access cavity is also important for a successful seal after the root canals have been filled. Any remaining bacteria or debris within the pulp chamber or root canals can lead to treatment failure.
