Presença do canal mésio-vestibular 2 em primeiros molares superiores – série de casos

Abstract

The aim of this study was to report a series of clinical cases that show how the presence of the mesiovestibular 2 canal l(MV2) in the first maxillary molar is truly found. Patients complained of spontaneous pain with a history of element 26 or 16, some with deep caries and extensive restorations. Vertical and horizontal percussion tests, thermal tests. and radiographic analysis were performed. The canal was disinfected with abundant irrigation of 2.5% sodium hypochlorite. After, the root canals were located with files # 8 and #10, then the foraminal patency was performed with the EASY system file #25.01, root canal preparations were performed with EASY files from the Logic series #25.05, #40.05 and files #25.04, #30.03, #35.03. After using each file, irrigation with sodium hypochlorite was performed. After the canals were prepared, the cone test was carried out. After drying the canals, the final filling was performed with calibrated Tanari cones and AH plus cement. It was concluded that the occurrence of MV2 canal is high in the first maxillary molars and their location for disinfection is of paramount importance.
