RESUMO
Background: Internal anatomy of maxillary first premolars is particularly multifaceted on account of the variation in number of roots and canal configuration. Maxillary first premolars with 3 roots are called as small molar or "radiculous" because of their similar anatomy to the maxillary first molars. The most demanding step in endodontic treatment is identification and proper access to pulp canals of certain teeth with atypical canal configurations. Methods of identification of such premolars can be by various aides. Case Presentation: The present case describes the application of Cone Beam-Computed Tomography in the diagnosis of extra root with extra canal in a three rooted maxillary right first premolar. Conclusions: Proper knowledge of the anatomical variations is a must for an endodontist to make a treatment successful. Utilizing the latest technology along with the traditional concepts can surely rule out the inaccuracy in the treatment involved in such cases.
RESUMO
Regenerative Endodontic Procedures can be defined as biologically based procedures designed to replace damaged structures including dentin and cells of the pulp dentin complex. The term revascularization is more commonly employed with regenerative procedures and describes reintroduction of vasculature in the root canal system. This case report describes the treatment of two nonvital immature teeth with infected pulp. Revitalization was attempted in two adjacent teeth by the same operator following similar protocol. In one of the teeth, revitalization was successful with continued root wall thickening, root lengthening and closure of the apex whereas in the adjacent tooth though root lengthening could not be achieved, a definite apical closure with irregular root wall thickening could be obtained.
