UPPER MOLAR WITH 4 ROOT CANALS, PULP NECROSIS, AND INSTRUMENTED WITH SOLLA S1 FILE – CASE REPORT

Abstract

A 32-year-old male patient with no comorbidities was referred to the private office of an endodontist for endodontic treatment of tooth 16. Clinically, he did not present fistula or edema. Radiographic examination revealed periapical bone radiolucency. Based on the clinical and radiographic examinations, asymptomatic apical periodontitis was diagnosed. After anesthesia and opening, the root canals were explored with manual files #08 and #10 (C Pilot). Electronic odontometry was performed with an apex locator to obtain the actual length of the tooth. The preparation of the mesiobuccal 1, mesiobuccal 1 and distobuccal canals was performed with Solla Files Collors S1 -35.04 files and the preparation of the palatine canal with Solla Files Collors 40.04 file. Foraminal patency was performed with Glide path Solla Collors 16/02. Obturation of the root canal system was performed using the single cone technique calibrated 35.04 in the mesiobuccal canal 1, mesiobuccal 1 and distobuccal canals and 40.04 in the palatine canal, associated with AH-Plus Jet cement. It is concluded that the Solla File Collors rotary file determined an efficient formatting of the root canal, and consequently, facilitated the obturation of the root canal system using the single cone technique in an upper molar with 4 root canals.
