Comparative Evaluation of Instrumentation Time and Quality of Obturation amongst Pediatric Rotary Endodontic System: An In Vivo Study

AIM: This study assesses the instrumentation time and quality of obturation of three pediatric rotary endodontic systems—GT nickel-titanium (NiTi) (Prime Pedo), controlled memory (CM) NiTi (Pro-AF-Baby Gold) and NiTi-titanium oxide (NiTi-TiO) (Kedo SG Blue). MATERIALS AND METHODS: A total of 60 children aged 4–8 were chosen at random for the study based on inclusion criteria that required pulpectomy in any of the primary molars and were separated into three groups of 20 samples, each based on the file system employed. The instrumentation time during the preparation of the canal is recorded using a stopwatch. An expert dentist was blinded to the instrumentation type and showed the periapical radiograph, which he or she graded depending on the quality of the obturation by categorizing it as underfill, optimal fill, or overfill. The observations were then recorded, tabulated, and statistically analyzed for the results. RESULTS: The least amount of instrumentation time was needed for NiTi-TiO (group III) files, followed by NiTi-CM (group II) and NiTi-GT (group I). NiTi-TiO (group III) has the most optimally filled and least underfilled obturations among the three rotary endodontic systems mentioned. Also, NiTi-TiO (group III) and NiTi-CM (group II) have the least similar overfilled obturations when compared with NiTi-GT (Group I). CONCLUSION: We conclude that NiTi-TiO needed the least amount of instrumentation time and generated the maximum optimally filled obturations based on our observations. CLINICAL SIGNIFICANCE: Pediatric rotary endodontic systems are more convenient to use and reduce chairside time; thus, their use in children with behavior control issues might be more suitable.
