Clinical and Radiographic Evaluation of WaveOne Gold Single-File System in Pulpectomy of Primary Molars: A Randomized Clinical Trial

Purpose: The current study evaluates the reciprocal WaveOne Gold single-file system regarding clinical and radiographic outcomes in ischolar_main canal treatment of primary molars. Method: This randomized clinical trial was carried out on 70 primary molars on 60 children in the age group from 4 to 7 years. The teeth selected for this study were randomly assigned into 2 groups according to the used endodontic preparation system. Group I: 35 primary molars were instrumented with WaveOne Gold reciprocating single-file system. Group II: 35 primary molars were instrumented with stainless steel K-files. All teeth were evaluated clinically and radigraphically for 12 months with periodic recall at 3, 6 and 12 months. Results: WaveOne Gold single-file system exhibited higher overall success rate over manual instrumentation, however, the difference between groups was not statistically significant (P >0.05). Conclusion: Single-file systems are promising instruments that have the power to be an alternative for manual instrumentation in primary molar pulpectomies.
