Comparative evaluation between the diameter of standardized cones and secondary cones B8 calibrated by calibration scale, measuring 1 mm from its tips (D1)
Journal Title: RSBO - Year 2009, Vol 6, Issue 1
Abstract
Introduction and objectives: The objectives of the present study were to evaluate and to compare the measures of the D1 diameter of standardized and secondary cones calibrated using a calibration scale through the measurement of the first millimeter of the cones with a digital caliper. Material and methods: Ten standardized gutta-percha cones of each type had been used (#25, #30, #35 and #40), whose manufacturers were Dentsply/Maillefer and Tanari, as well as secondary cones B8 calibrated by a calibration scale, making a total of 160 cones.With the aid of a digital electronic caliper, the diameter to 1 mm back from the tip of the cone (D1) was verified. Results: There was significant difference in one of the manufacturers’ brand, between the standardized and the calibrated cones. When compared, the caliper of the standardized cones of both brands presented difference in statistics,what did not occur when the cones had been calibrated by the calibration scale. Conclusion: The Tanari cones, on average, had a superior result when compared to the calibrated and to the Dentsply cones, in this order.
