| Summary: | Background and aims. The superiority of rotary systems has been reported in several clinical studies on permanent
teeth. This study consisted of radiographic assessment and chair time of rotary instruments in the pulpectomy of primary
second molar teeth.
Materials and methods. In this randomized controlled clinical study, 46 children, 3-6 years of age, were selected. The
patients were divided randomly into two groups. In the first group (group A) pulpectomy was carried out with hand instruments
and in the second group (group B) the Rotary FlexMaster System was used. T-test and chi-squared test were used to
analyze data.
Results. The mean instrumentation time in group A was significantly more than that in group B (P < 0.001). Also there
was a significant difference between both groups in relation to the distance between the apex of mesial root (P < 0.001) and
distal root (P = 0.007) and the canal filling level.
Conclusion. Superior radiographic findings and less chair time of pulpectomy with rotary instruments in second primary
molar teeth were achieved. |
