Cone-beam computed tomographic evaluation of the quality of obturation using different pediatric rotary file systems in primary teeth

Abstract

Aim and objective: To compare and evaluate the efficacy of three different pediatric rotary file systems in primary molars using cone-beam computed tomography (CBCT). Materials and methods: Thirty extracted mandibular primary molars were selected and divided into three groups with ten teeth each, instrumented with Kedo SG Blue rotary files, Pro AF Baby gold rotary files, and Pedo Flex rotary files, respectively. Root canal obturation was done with zinc-oxide eugenol cement and the quality of obturation was assessed using CBCT based on the extent of filling as underfilled or optimally filled and the presence or absence of voids within the filling. The data were statistically analyzed using the Chi-square test. Results: Among the three groups, the Kedo SG Blue group showed more number of optimally filled teeth with minimal voids (p < 0.05) followed by the Pro AF Baby gold group and Pedo Flex group. Conclusion: Within the study limitations, the Kedo SG Blue group showed ideal endodontic obturation when compared with Pro AF baby gold and Pedo Flex rotary file systems. Clinical significance: The present study will guide the pedodontists regarding the efficacy of pediatric rotary file systems and their usage protocols.
