UPPER LEFT FIRST PREMOLAR WITH THREE ROOTS AND THREE ROOT CANALS

Abstract

This clinical case report describes a case of a left upper first premolar with three separate roots prepared with a Solla Collors file in a single session. A 37-year-old female patient with no history of systemic diseases sought private practice. During clinical examination, the tooth showed no response after the vitality test, and the radiographic examination showed widening of the periodontal space and suspicion of three roots. The probable diagnosis was pulp necrosis. After anesthesia, the tooth was isolated and the coronal access and irrigation with 2% Chlorhexidine gel and saline solution were performed. The root canals were prepared with Solla Files Collors 35/04 files in the mesiovestibular and distovestibular canals and 40/04 in the palatine canal. Foraminal patency was achieved with a Solla File Glidepath #16/02 file. The obturation technique was performed with a single cone associated with Bio-C Selaler cement. It is concluded that the first upper premolars are teeth that are prone to internal anatomical variations, one of which is the existence of a third root canal.
