ANATOMICAL VARIATION OF THE MAXILLARY FIRST PREMOLAR – CASE REPORT
Keywords
Abstract
The present clinical case report describes a rare case of maxillary first premolar with three separate roots prepared with Solla Collors file in a single session on tooth 24. A 26-year-old female patient presented to the dental office (MFB specialized endodontics) in the city of Lauro de Freitas, BA, complaining of painful symptoms in the left maxillary first premolar, tooth #24. On clinical radiographic examination, it was observed that the canal lumen only in the cervical third of the root, the contour of the periodontal ligaments suggested an atypical anatomy with possibly more than 2 canals. Root canal instrumentation was performed using the electronic apical locator at zero: #35.04 (Solla Files) in the vestibular canals and #40.04 in the palatal canal. The filling of the root canal system was performed using the calibrated single cone technique associated with cement, the AH-Plus. The preparation of the root canals with Solla Collors file was concluded, determining an adequate modeling, in teeth with anatomical variation of premolar with three roots.
