Aim: To compare the percentage increase in the cross-sectional area of root canals, at the level of 3 mm from the root apex after instrumentation with two single instrument systems.
Methods: The roots of 19 extracted mandibular first molars were sectioned 3 mm short of the apex level, with the final 2 millimeters of each root removed and discarded in order to enable the preoperative area to be measured by stereomicroscopy. Subsequently, the roots were instrumented with the SAF and Reciproc 25/.08 systems, alternating the technique used per canal from root to root, and a new measurement was performed. After, the percentage increase in area was calculated considering the values of the original and the final area. The Student’s t-test was applied to the results, with a level of significance set at 5%.
Results: The percentage increase in area of the root canals was significantly higher for the Reciproc (p = 0.001) when compared to the SAF group. In the canals instrumented with the SAF system, the mean increase in area was 53.5%, while in those using the Reciproc system, it was 154.5%.
Conclusion: The Reciproc system produced a 3-fold higher percentage increase in the cross-sectional area of the root canals at the level of 3 mm from the root apex than did the SAF system.
