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

Abstract

Pulpal treatment in deciduous teeth is done to maintain the tooth in position for proper function including mastication, phonation and preserving the arch length until the permanent teeth erupt. Pulpectomy is a conservative treatment approach in which pulp chamber and canals are accessed for cleaning and debridement followed by filling with a suitable material. Root canals in primary teeth are different from permanent teeth in being short, slender and more divergent with multiple accessory canals and continuously shifting apical foramen due to resorption. Therefore, the technique is sensitive in primary teeth. Conventional hand files were used initially then rotary system was introduced. NiTi rotary file system provide some of the advantages like short instrumentation time, cost-effective and consistent obturations along with improving patient’s cooperation. But there were various limitations of using adult rotary files in children because of larger file length and taper which causes lateral perforations and over-instrumentation. Hence, NiTi rotary files were designed for children. Kedo-S file system was the first file system to be introduced. After that, many systems have evolved specifically for children. The present literature review will discuss various rotary file systems available for children. Key words: Pediatric endodontics, Pediatric NiTi rotary files, Pulpectomy.
