Evaluation of Clinical Efficiency of Two Single-file Ni-Ti Rotary Systems in Performing Root Canal Treatment in Primary Teeth: A Randomized Clinical Trial
Year: 2026
Type: article
Study design: Clinical Trial
Abstract: Background: The conventional procedure using stainless steel hand files is very time-consuming and has associated disadvantages. A literature review demonstrates the effectiveness of nickel-titanium (Ni-Ti) rotary files in this regard. Technological advancements have led to the development of various single-file Ni-Ti rotary systems, such as Kedo-S and XP-Endo Shaper. Aim: To compare the instrumentation time and quality of obturation in primary molars, assessed by the Coll and Sadrian criteria, using two single-file Ni-Ti rotary systems, Kedo-S and XP-Endo Shaper. Materials and methods: test for instrumentation time and Pearson's Chi-squared test for quality of obturation. Results: = 0.350). A greater percentage of optimal fills (84%) and a fewer number of voids were evident with XP-Endo Shaper. Conclusion: The use of the adaptive XP-Endo Shaper resulted in reduced instrumentation time and better quality of obturation. Clinical significance: Pulpectomies performed under general anesthesia, where time is a constraint, can benefit from the use of single-file rotary systems. Considering the quality of obturation, XP-Endo Shaper performed better, with fewer voids and a greater number of optimal fills due to its adaptive technology. CTRI Reg No: CTRI/2025/04/084040.
