Abstract :Purpose: The present study investigated the root canal configuration of maxillary second molars with root fusion using micro-computed tomography insert ignore into journalissuearticles values(micro-CT);. Materials & Methods: A total of 136 fused maxillary second molars were scanned with micro-computed tomography. Images were transferred to CTAn v.1.18.8 software insert ignore into journalissuearticles values(Bruker-microCT); to obtain three-dimensional models. The specimens were classified according to the fusion type. According to Vertucci, classification of the root canal configuration of fused roots was determined using CTVol v. 2.3.2.0 insert ignore into journalissuearticles values(Bruker-microCT); and DataViewer v.1.5.6 insert ignore into journalissuearticles values(Bruker-microCT); softwares. The specimens that could not be represented were also specified. The frequency of canal configuration according to the fusion type was calculated. Results: For Type 1 fusion insert ignore into journalissuearticles values(n=40); and Type 2 fusion insert ignore into journalissuearticles values(n=22);, the most common canal configuration for mesiobuccal insert ignore into journalissuearticles values(MB);, distobuccal insert ignore into journalissuearticles values(DB); and palatal insert ignore into journalissuearticles values(P); canals was Type I. In type 3 fusion specimens insert ignore into journalissuearticles values(n = 21);, DB and P canals were completely fused in 1 sample in accordance with Vertucci type IV, while in the remaining specimens, types II, I, V, VI and IV were observed in decreasing order in the MB canal. In type 4 fusion, MB and DB canals were completely fused in 4 of 21 specimens and showed Vertucci type VI, II, I and III configurations. In the remaining 17 samples, MB had Vertucci type I, II, IV, V, VI, VII configurations, while DB showed type I, V and III configurations. In 7 samples with type 5 fusion all canals displayed different configurations. In type 6 fusion, the canal configurations of 6 samples could not be classified. Type II, I, and V configurations were seen in 9 of the remaining 19 samples with a single canal. Conclusion: Vertucci type I was the dominant canal configuration in the P and DB, however, MB showed much more diverse configurations either independently or when included in fusion.
