![]() The taper and length were limitations in using existing rotary systems for permanent teeth when used in primary teeth. Rotary instrumentation performed in primary teeth was through use of rotary files designed specifically for permanent teeth until 2016. ![]() concluded that usage of rotary files in deciduous teeth were more efficient in both root canal shaping and preparation time, facilitating higher quality of obturation of the root canal. It was found to be an efficient technique to debride the uneven walls of primary root canals and produce a uniform root canal shape that ended with a predictable obturation. in 2000 through use of Profile 0.04 taper rotary instruments in pulpectomy of primary teeth. To overcome these limitations, Ni–Ti rotary files were first introduced in pediatric endodontics by Barr et al. Despite being commonly used as the most standard and widely accepted method for biomechanical preparation in primary teeth, certain limitations were associated with hand files as being time-consuming and the occurrence of iatrogenic errors such as lateral perforations, zipping, apical blockage, and canal transportation. The standardized method for cleaning and shaping of primary teeth was employed using hand files. īiomechanical preparation is one of the most crucial phases of pulpectomy in primary teeth, which are targeted primarily during debridement of the canals. ![]() Pulpectomy is considered the treatment of choice for pulpally involved primary teeth in which the pulpal tissue is infected due to caries or trauma.
