Comparison of quality of obturation instrumentation time and post operative pain after pulpectomy in primary molars using manual k files kedo s and kedo s square rotary files system a double blinded randomised clinical trial

Abstract

ABSTRACT newlineBackground newlinePulpectomy is the only viable option to retain a primary tooth with irreversible newlinepulpal pathosis in its position until physiological exfoliation. Biomechanical preparation newlineis the major step in determining the success of pulpectomy. In the field of paediatric newlineendodontics, there has been a progression with the type of instruments used for canal newlinepreparation. newlineAim newlineTo compare the quality of obturation, instrumentation time and post-operative newlinepain after pulpectomy in primary molars using manual K-files, Kedo-S and Kedo-S newlineSquare rotary file systems. newlineMaterials and Method newlineA double blinded randomized control trial was conducted in 45 children between newlinethe age group of 4 and 8 years, who were indicated for pulpectomy in any one of the newlineprimary mandibular molars. The children were divided into 3 groups with 15 teeth in newlineeach. The canal preparation was done using hand K-files, Kedo-S files, and Kedo-S newline9 newlineSquare files. The time taken for instrumentation was recorded using a stopwatch. The newlinequality of obturation was evaluated using post-operative radiograph and newlinepost-operative pain was assessed with modified Wong-Baker FacesPain scale. newlineResults newlineForty Five children, consisting of 23 male and 22 females, participated in the newlinestudy. An equal distribution of participants with respect to (P=0.215), gender (P=0.315) newlineand teeth (P=0.260) was observed between the groups. Instrumentation time was newlineminimum in rotary Kedo-S Square files (53.23 ± 9.60 seconds) followed by Kedo-S newlinefiles (82.70 ± 11.86 seconds). The preparation time was maximum with manual K-files newline(121.43 ± 20.18 seconds). Kedo-S square files provided a higher number of optimally newlinefilled canals (66.4%). All the three instrumentations equally showed the tendency to newlineproduce voids in the obturation. Rotary files Kedo-S Square followed by Kedo-S newlineshowed less post-operative pain compared to K-files. newlineConclusion newlineThe use of pediatric rotary instruments for canal preparation during pulpectomy newlinewill result in better quality of obturation in reduced time
