Perfuração endodôntica em assoalho de câmara pulpar: revisão de literatura

Abstract

Endodontic perforations are accidental communications between the root canal system and the periodontal tissues, often resulting from iatrogenic factors during access or canal preparation. When located in the pulpal chamber floor, they present significant clinical challenges due to the proximity to critical periodontal structures. This literature review aimed to address the etiological, diagnostic, prognostic, and therapeutic aspects related to this specific type of perforation. Studies were analyzed concerning variables influencing treatment success, such as perforation size and location, time elapsed before sealing, presence of contamination, and the material used. Among the available biomaterials, mineral trioxide aggregate (MTA) stands out as the preferred option due to its biocompatibility, tissue regeneration potential, and excellent sealing ability. It is concluded that early diagnosis and appropriate management using bioactive materials are key to preserving the affected tooth and ensuring successful endodontic outcomes
