ABSTRACT Aim The aim of this study was to compare canal transportation and centering ability of Twisted files (TF) and ProTaper (PT) files with conventional stainless steel (SS) K files. Materials and methods Thirty mandibular premolar teeth with root curvature of 25 to 35° were selected. The samples were randomly divided into three groups of 10 each according to the type of files used for instrumentation. Group I was instrumented using TF, group II with PT files according to the manufacturer's recommendations, and group III with samples prepared with precurved SS K files using a step-back technique. After preparation, the samples were assessed using spiral computed tomography. Three sections were recorded at coronal, middle, and apical levels. Amount of transportation was assessed comparing with preinstrumentation images. Centering ability was calculated using Gambill's formula. The three groups were statistically compared using Student's t-test. Results Twisted files showed the least canal transportation and the best centering ability followed by PT file system. Stainless steel K files showed the highest transportation and least centering ability. Conclusion Twisted files showed the least amount of transportation and better centering compared with the other file systems. Clinical significance The study gives information of TF, a recently introduced rotary system (2008) with regard to its efficacy in preparing curved root canals. This study has shown that the centering ratio of rotary nickel titanium was better than that of SS files. How to cite this article Rejula F, Christalin R, Ahmed W, Dinakaran S, Gopinathan AS, Babu A.

The aim of this study was to evaluate the difference in the angle of curvature, radius of curvature and canal volume before and after root canal shaping by Protaper and Mtwo rotary systems using spiral computed tomography (spiral CT).  45 colored resin blocks with a single canal and 20° curvature were taken and divided into 3 groups of 15 samples each. Iodine based contrast was injected into the canals and preoperative scanning was done with spiral CT. The canals were prepared with Mtwo in group I, Protaper in group II and group III was kept as a negative control. All the canals were filled with contrast solution and subjected to postoperative scanning. Pre and postoperative images were recorded and compared and statistically analyzed using Digital Imaging and Communications in Medicine (DICOM) software. Group I did not show any change whereas group II showed significant change in the angle and radii of curvature in which the apical canal curvature was straightened. There was no significant difference in the volumetric change of root canal between the two systems. Keywords: Spital CT; Protaper: Mtwo:, Root canal configuration:

ABSTRACT Fusion is a developmental anomaly in tooth morphology, which may be due to either union of two separate tooth buds or partial splitting of a single tooth bud. A thorough understanding of root canal anatomy is an essential prerequisite for a successful endodontic treatment. This case report describes successful endodontic management of a maxillary left lateral incisor fused with a supernumerary tooth using spiral computed tomography (SCT) as a diagnostic aid. A patient reported with a painless swelling in the maxillary anterior region associated with a fused maxillary lateral incisor. Spiral CT was performed to better understand the complex root canal anatomy. Endodontic treatment was done using methyl trioxide aggregate (MTA) as apical plug and obturation by thermoplasticized gutta-percha. The tooth was completely asymptomatic at 1-year follow-up showing signs of healing. The present case report emphasizes on the importance of three-dimensional (3D) imaging techniques, such as SCT in cases of developmental anomalies having complicated root canal morphology for successful endodontic therapy.

Aim: T assess the root canal transportation caused by these rotary NiTi reciprocating file systems using 3D cone beam computed tomography Method: This experimental study was conducted on 60 samples of rotary NiTi reciprocating file systems using CBCT. The extent of canal transportation and the centering ratio was analyzed using independent sample t test. The significance level was set at 95%. Results: Mean apical canal transportation was lower in wave one Gold groups as compare to Reciproc (0.8724±0.04SD vs 0.9463±0.02SD, p=0.000). Mean apical canal transportation at 5 mm was lower in wave one gold group as compare to reciproc blue group (0.5610±0.02SD vs 0.7253±0.06SD, p=0.000). Mean apical canal transportation at 8mm was lower in wave one group as compare to reciproc blue (0.358±0.03SD vs 0.5766±0.10SD, p=0.000). Conclusion: Wave one Gold had high centering ability and lower canal transportation as compare to Reciproc Blue single file system. CBCT is an efficient method of understanding Canal transportation Keywords: CBCT, NiTi wire, Root canal transportation, Reciproc blue

The Difference

Abstract Background: Cleaning and shaping of the root canal system is important in an endodontic treatment. Canal transportation is a common procedural error in preparation of curved canals. This study aimed to compare the canal transportation and centering ratio of two rotary files in curved canals using cone-beam computed tomography (CBCT). Methods: 44 extracted human mandibular first molars with mature apices and apical curvature of 10° to 30° were selected. The samples were randomly divided into two groups (n=22) with similar curvature. The canals were prepared with ProTaper and XP-endo Shaper file systems according to the manufacturers’ instructions. CBCT images were captured using Cranex 3D CBCT system before and after root canal preparation, and canal transportation and centering ratio of the files at 3, 4 and 5 mm from the apex were calculated. Data were analyzed and compared between two groups using independent t-test at 0.05 level of significance.Results: The ProTaper Universal caused greater canal transportation and had lower centering ratio than XP-endo Shaper in both mesiodistal and buccolingual directions at all levels from the apex. The difference between two groups regarding transportation was significant at all levels from the apex in buccolingual direction (P<0.05) except for 3 mm from the apex (P>0.05). The difference between two groups regarding centering ratio was not significant (P>0.05) in mesiodistal direction at all levels except for 4 mm from the apex (P<0.05). Conclusion:The ProTaper Universal causes greater canal transportation in both buccolingual and mesiodistal directions than XP-endo Shaper.
