Nickel-Titanium (Ni-Ti) instrument are widely used for root canal preparation in permanent tooth compared to primary teeth. Hand instrumentation technique remains the conventional method for root canal preparation in primary teeth. The time taken for root canal preparation with the conventional method is more resulting in patients and clinicians fatigue. Recently Ni-Ti rotary files designed for permanent tooth has been used for root canal preparation in primary teeth. Using rotary instruments for primary tooth pulpectomies resulted in better and predictable root canal filling. This article presents case reports of pulpectomy treatment performed using Kedo-S an exclusive paediatric Ni-Ti rotary files. The advantages and disadvantages in use of Ni-Ti rotary files in primary teeth are discussed in this article.
与乳牙相比，镍钛（Ni-Ti）器械在恒牙根管预备中应用广泛。手工器械操作技术仍是乳牙根管预备的传统方法。传统方法进行根管预备耗时较长，会导致患者和临床医生疲劳。近来，为恒牙设计的镍钛旋转锉已用于乳牙根管预备。在乳牙牙髓摘除术中使用旋转器械可获得更好且可预测的根管充填效果。本文介绍了使用Kedo-S（一种专用的儿童镍钛旋转锉）进行牙髓摘除术治疗的病例报告。本文还讨论了在乳牙中使用镍钛旋转锉的优缺点。
