Özet
Background: The purpose of the study was to compare pediatric rotary files with hand K-files regarding the amount of dentin removal, root canal transportation, root canal surface area and volume in primary mandibular second molars using Cone-Beam Computed Tomography (CBCT). Methods: A total of 36 primary teeth were randomly divided into four groups; K-file, Fanta AF Baby file, EndoArt Ni-Ti Pedo file Gold Kit, MiniSCOPE Ni-Ti Gold Pediatric file. Samples were imaged with CBCT before and after canal instrumentation. For root canal surface area and volume measurements, 3Matic (Materialize, Belgium) software was used. Linear measurements were performed using NNT iRYS software. Data analysis was conducted using the Dunn’s test and the Kruskal Wallis test. A significance level of p < 0.05 was used. Results: Compared to pediatric rotary files, the K-file was shown to remove a statistically greater amount of dentin at the coronal level (p = 0.032). The difference in dentin thickness with the K-file was significantly greater than with the EndoArt file (p = 0.017) and the MiniSCOPE file (p = 0.007). The volume difference with the MiniSCOPE file was significantly less than with the Fanta file (p = 0.002) and the EndoArt file (p = 0.032). Root canal transportation was significantly greater with the K-file compared to the Fanta AF Baby file in both the oblique (p = 0.031) and buccal-lingual (p = 0.006) directions. Conclusions: Pediatric rotary files could be considered an efficient alternative to the hand K-file in biomechanical instrumentation. Three dimensional analysis can provide better comprehensive approach to evaluating the pediatric rotary instruments.
