Endodontic treatment in a lower first premolar with 3 root canals: Clinical case study

The dentist must be aware of anatomical diversities during endodontic treatment.Some dental elements may differ in the number of roots and root canals, so if a root canal is not formatted it may lead to failure of endodontic therapy.The objective of this study is to evaluate, through a case report, endodontic treatment in a lower first premolar with 3 root canals.A patient was treated who had a lower premolar in need of endodontic treatment due to a process of pulp necrosis.In the first session, anesthesia, access surgery, location of the 3 root canals, absolute isolation, irrigation with 2.5% sodium hypochlorite, odontometry, mechanized instrumentation, drying and insertion of intracanal medication (Calcium hydroxide) in all canals were performed..In the second session (after 15 days), the intracanal medication was removed and the root canals were filled with the continuous wave technique.The patient appears asymptomatic.Case study alerts dental surgeons to the need to know the anatomical diversities in lower premolars and that endodontic treatment allows the remission of the pathological process and the maintenance of the function and aesthetics of the dental element.
