Fracture Incidence of Kedo-S Square Pediatric Rotary Files: A Prospective Clinical Study

Abstract

Objective The primary focus of this clinical study was to analyze the probability of occurrence of instrument fracture after root canal preparation of primary molars with the help of Kedo-S Square pediatric rotary file. Materials and Methods Three experienced specialists treated 100 primary maxillary and mandibular molars (335 root canals) using a standardized protocol over 2 months. Biomechanical preparations were carried out using Kedo-S Square file, as per the suggestions given by the manufacturer. Every instrument in Group A helped handle three clinical cases, while for groups B, C and D, they helped in handling 5, 9, and 12 cases, respectively. Making use of an operational microscope, the rotary files, after being pulled out from the canal, were observed. The values were tabulated, and descriptive statistics were performed. Results There were two fractures (2%), of which 1 occurred in group C in the apical 1/3rd of distobuccal canal of maxillary molar, and the other occurred in group D in the apical 1/3rd of mesiobuccal canal of maxillary molar. Conclusions The fracture rate of Kedo-S Square rotary file is quite low. It is primarily in the buccal canals of the maxillary molars and the apical third of the root canal that the instrument has a greater probability of separation.

A instrumentação mecanizada no tratamento endodôntico de dentes decíduos: Uma revisão integrativa

“…Toda via, não foram observadas diferenças significativas no comportamento das crianças avaliadas, no limite apical das obturações, ou na dor pós-operatória (Barasoul et al, 2020). A instrumentação mecanizada também se mostrou mais eficaz na redução da contaminação microbiana (39%-95%) (Lakshmanan et al, 2022).…”

Rotary File Systems Designed Exclusively for Pediatric Patients: A Literature Review

“…[11] These files have a low fracture rate. [12] Rasha H Mohamed found more conservative preparation, superior taper ability and lowest instrumentation time using Kedo-S Square files compared to hand K-and H-files on CBCT evaluation. [13] • Kedo-S Plus: Fifth generation This is the newly introduced file system by Kedo S. It has a uniform cross section with dual core material, which is heat treated along with titanium oxide coating at apical and middle region.…”
