Comparison of Shaping Ability between Continuous Rotary and Manual Instrumentations in Pediatric Endodontics

Abstract

Objective: The aim of this in vitro study was to evaluate the efficacy of rotary EndoArt Ni-Ti Gold Pedo Kit and K-files in shaping ability, canal transportation, centering ability and instrumentation time in primary molars. Methods: For the study total of 30 extracted primary molars root with minimum 7mm root length were selected. Shaping of root canals in primary molars were done using the two systems, and CBCT and specialized software were used for scanning and analysis of pre-operative and post-operative to evaluate the groups for their shaping properties, apical transportation and preparation time in primary root canals. Results: No differences were found in canal transportation measures and instrumentation time between the two groups (p>0.05). The EndoArt group removed more dentin compared to K-file in all sides of the root curvature. The statistical differences were significant for coronal and middle third of the root (p<0.05). Conclusions: Under the conditions of this study, rotary EndoArt Ni-Ti Gold Pedo Kit provided more conical canals than K-files in primary teeth.

Cone-beam computed tomography evaluation of shaping ability of kedo-S square and fanta AF™ baby rotary files compared to manual K-files in root canal preparation of primary anterior teeth

“…The lower tendency toward apical transportation in the rotary file systems may be credited to its design with a non-cutting tip [ 5 , 10 ]. This agreed with Güçyetmez et al [ 32 ] study in which a non-significant statistical difference in the apical transportation values was found between K-files & EndoArt rotary files. The highest mesial transportation in the Kedo-S Square group was found in the middle third (40%) in this study while the highest mesial transportation in the Fanta AF™ Baby group was present in the apical third (56%); this may be clarified by the operator’s tendency to do more vigorous preparation on the side opposite to the most favorable support.…”

“…The present study findings agreed with Mohamed et al [ 5 ] who revealed that the Kedo-S Square file had a minimal quantity of removed dentin contrasted to manual K- & H-files. However, it was disagreed with Güçyetmez et al [ 32 ] who concluded that EndoArt rotary files eliminated more dentin than K-files in the coronal and middle root canal thirds. Using pairwise comparison, a statistically significant difference was found between Kedo-S Square and K-files at different root canal levels in the amount of the removed dentin on both mesial and distal sides.…”

“…Literatür tarandığında EndoArt eğesiyle ilgili yapılmıĢ sadece iki çalıĢma mevcuttur. Bu çalıĢmaların birinde eğenin döngüsel yorulma direnci incelenmiĢ (31) diğerinde ise süt diĢlerinde EndoArt Pedo Kitmanuel K-tipi el eğesi preparasyon yeterliliği açısından karĢılaĢtırılmıĢtır (32). Piyasaya yeni sürülen bir döner eğe sistemi olduğu için eğenin kanal yenileme sırasında apikalden taĢan madde miktarı ilk kez çalıĢmamızda incelenmiĢtir.…”
