Double Root Anatomical Variations in a Single Patient: Endodontic Treatment and Rehabilitation of a Three-rooted First Premolar. Case Report
Abnormal interaction between oral epithelium and underlying mesenchematic tissue during odontogenesis could result in teeth with an anatomical variation. First maxilar premolar has such variable root canal morphology. However, (0.2-6% of cases) a three-rooted premolar is particularly uncommon. First...

| Sumario: | Abnormal interaction between oral epithelium and underlying mesenchematic tissue during odontogenesis could result in teeth with an anatomical variation. First maxilar premolar has such variable root canal morphology. However, (0.2-6% of cases) a three-rooted premolar is particularly uncommon. First mandibular premolar frequently has one root and one single canal (75% of cases), however, a tooth with two canals and two separate roots could be found (19.5-22.5%). Execution of an accurate diagnosis of root canal system is essential to perform a successful endodontic treatment and tooth rehabilitation. This article describes diagnosis, endodontic treatment and rehabilitation (means single crown) of a maxillary three-rooted and three-canal first premolar, and a non-endodontically treated mandibular first premolar with two canals and two independent roots in a single patient. |
