It was concluded that the use of Ni-Ti rotary files for root canal preparation in primary teeth was cost-effective, less time-consuming, and resulted in consistently uniform and predictable fillings. Maintaining the original path of the root canal was essential to ensure the integrity of permanent successor. The crown down instrumentation technique was not necessary as the primary root dentin cuts more easily than permanent teeth. Copious irrigation was must to keep the canals moist. It was suggested that frequent inspection of each file for flute unwinding or distortion was important, and the file may be discarded after use on 5 primary teeth. The canals were cleansed and shaped with sequentially larger files until the last file. It was inserted into the canal while rotating at a slow speed of 150–300 rpm till the calculated working length, as determined by pretreatment radiography. ![]() A NiTi ProFile 0.04 was chosen that approximates the canal size. 16 the pulpectomy procedure began with a standard access and removal of coronal tissue. It has a triple U-shaped cross-sectional design with flat radial lands, a non-cutting tip, and constant taper with a 20° helical angle and constant pitch. 1, 2 Most recently, Kedo-S (the first rotary Paedodontic file) has made a major breakthrough in the field of pediatric endodontics. Many authors have reported the clinical success of Profile, ProTaper, Mtwo, FlexMaster, Light Speed LSX, Hero 642, K3, and WaveOne rotary files in primary teeth. 4 was first to demonstrate the use of NiTi rotary files in primary molars advocating the same principles of biomechanical preparation as described for permanent teeth. 3, 4, 10 To overcome such barriers, various modified protocols have been introduced to prevent any undesirable complications. However, the bizarre root canal morphology and thinner root dentin limited the use of rotary endodontics in primary teeth. 9 These changes lead to the introduction of rotary endodontics in pediatric dentistry. Rotary instrumentation has made a quantum leap in the field of endodontics. 6 With changing trends, much attention has been directed towards making pulpectomy a less time-consuming and a more-efficient procedure. 8 However, its use has been fairly limited to permanent teeth. 6, 7 Therefore, more and more practitioners are exploring the benefits of rotary endodontics in modern-day practice. 6 Although manual instrumentation for root canal preparation is widely used in primary teeth, there are limitations regarding patient cooperation and time consumption. 4, 5 Success of a pulpectomy procedure mainly depends upon the biomechanical preparation of the root canal systems. 1– 3 In modern pedodontic practice, pulpectomy of such teeth is regarded as a treatment of choice over extraction. In pediatric dentistry, premature loss of necrotic primary molars has been a matter of great concern over the years. ![]()
