ABSCESSO PERIAPICAL COM FÍSTULA EM DENTE MOLAR SUPERIOR COM 4° CANAL NÃO OBTURADO: revisão de literatura

Abstract

Periapical abscess with fistula in an upper molar tooth is a clinical condition that originates from infection of the dental pulp, resulting in the formation of pus in the region around the tooth root. This condition not only causes severe pain, swelling, and discomfort, but it can also lead to serious systemic complications if not treated properly. The challenge intensifies when the infection is associated with the presence of a fourth channel (MV2) in the maxillary first molar. Objective: The objective of this study was to review the literature on the main complications of an upper molar with an unfilled fourth canal. Methodology: This study consists of a literature review carried out in the Pubmed, MedLine, Scielo, Google Scholar, LILACS databases, using the keywords: "fourth canal", "periapical abscess" and "computed tomography". Results: The results indicate that periapical abscess may complicate diagnosis and treatment of infections. In addition, the fourth canal of the maxillary molar poses a significant challenge to endodontics, making clinical management more complex. Conclusion: This review highlights the importance of imaging tests, such as cone beam computed tomography, for the identification of these anatomical conditions. It is concluded that an early diagnosis and treatment adapted to the patient's needs are essential to prevent the progression of infections and complications associated with these anomalies.
