To achieve healing of the periapical lesion, one must obtain and maintain a decontaminated root canal system. System is to be emphasized, because the root canal system does not merely consist of tapering cone-shaped canals from orifice to apex , but rather, can and often is an intricate labyrinth of canals that diverge and weave to form an ...
Root canal procedure: unhealthy or injured tooth, subsequent creation of an access cavity with a dental handpiece, cleaning and shaping the root canals with an endodontic file, and restoration with gutta-percha filling and a crown Removing infected pulp during a root canal procedure.

Pericoronitis is inflammation of the soft tissues surrounding the crown of a partially erupted tooth, [1] including the gingiva (gums) and the dental follicle.
