Comparative Evaluation of Dentin Removal and Taper of Root Canal Preparation of Hand K File, ProTaper Rotary File, and Kedo S Rotary File in Primary Molars Using Cone-beam Computed Tomography

The aim of the present study is to compare cone beam computed tomography and periapical digital radiography for the evaluation of root canal preparation. Nine extracted human molars were used in this study. Following access cavity preparation, mesio-buccal roots of maxillary and mesial roots of mandibular molars were prepared and the remaining roots were cut off. Three amalgam cavities were prepared on the coronal part of the teeth and were filled with amalgam to be used as landmarks. Specimens were scanned using cone-beam computed tomography and periapical digital radiograph images were obtained before and after root canal preparation. WaveOne Gold Primary was used for root canal preparation to full working length. Specimens were then scanned using CBCT and a periapical radiograph for the after-instrumentation images. The transportation and centering ratio were measured and calculated on the CBCT and periapical radiographic images. The Bland–Altman method was used for detecting the bias in the evaluation of agreement between the two methods’ measurements. There was agreement between the two methods’ measurements using CBCT scans and periapical digital radiographic images in the evaluation of transportation and centering ratio parameters. The two methods could be used interchangeably in measurements of transportation and calculating the centering ratio.

This study detected procedural errors created by rotary nickel-titanium (NiTi) instruments during root canal preparation by two imaging methods. Forty extracted human maxillary and mandibular molars were divided randomly into two groups and treated by two endodontists (n=10) and two undergraduate dental students (n=10). The ProTaper UniversalTM Rotary System was used to shape the canals and then they were filled using AH PlusTM sealer and gutta-percha. Periapical radiographs (PR) and cone beam computed tomography (CBCT) images were obtained and two examiners, who evaluated them to verify the occurrence of procedural errors (fractured instruments, perforations, and canal transportation). The Chi-square test at 0.05 level of significance was used for statistical analyses. There were no significant differences (p>0.05) between the imaging methods. In the analysis of procedural errors, there was no significant difference (p>0.05) between the groups of operators (endodontists vs. students) nor between tooth groups (maxillary molars vs. mandibular molars). In view of the low incidence of procedural errors during root canal preparation performed by students the introduction of rotary NiTi instruments has potential in undergraduate teaching. PR and CBCT permitted the detection of procedural errors, but the CBCT images offer more recourse for diagnosis.

Canal Morphology

ABSTRACT Introduction Endodontic treatment requires knowledge of root canal morphology and its commonly occurring variation. The utility and relevance of cone beam computed tomography (CBCT) to the practice of endodontics is reported with increasing frequency in the field of endodontics for successful procedures. Therefore, the present study is undertaken to assess the variation in number and morphology of the root canals of primary molars. Materials and methods Extracted primary molars with at least two-thirds of intact root, and 7 to 12 mm length were cleaned in water and stored in 0.5% sodium hypochlorite for 1 week. Thereafter, the anatomy of the root canals of these primary molars was assessed through CBCT. Results In the present study, the majority of canals were ribbon shaped. Accessory canals were few and maximum number was found to be present in mesiobuccal root of maxillary first molar and the least in mesiobuccal root of mandibular second molar. Conclusion The CBCT proved to be as accurate as the gold standard in studying the presence of accessory canals with clinical applicability. This study highlights the usefulness of CBCT imaging for accurate diagnosis of the unusual canal morphology. How to cite this article Joshi N, Deshpande A, Poonacha KS, Bargale S, Naik K, Mehta D.

Canal Transportation

Introduction: The aim of this study was to evaluate, using cone-beam computed tomography (CBCT), transportation and centralization of different nickel-titanium (NiTi) rotary instruments. Methods: One hundred and twenty eight mandibular premolars were selected and instrumented using the following brands of NiTi files: WaveOne, WaveOne Gold, Reciproc, ProTaper Next, ProTaper Gold, Mtwo, BioRaCe and RaCe. CBCT imaging was performed before and after root canal preparation to obtain measurements of mesial and distal dentin walls and calculations of root canal transportation and centralization. A normal distribution of data was confirmed by the Kolmogorov-Smirnov and Levene tests, and results were assessed using the Kruskal-Wallis test. Statistical significance was set at 5%. Results: ProTaper Gold produced the lowest canal transportation values, and RaCe, the highest. ProTaper Gold files also showed the highest values for centering ability, whereas BioRaCe showed the lowest. No significant differences were found across the different instruments in terms of canal transportation and centering ability (P > 0.05). Conclusion: Based on the methodology employed, all instruments used for root canal preparation of mandibular premolars performed similarly with regard to canal transportation and centering ability.
