Objective:
To study the reliability of the degree of root canal curvatures with Schneider's and Weine's methods.
Methods:
Fifty-one selected premolars were measured by three trained examiners with Schneider's and Weine's methods.
Results:
Among the three examiners, the datas were not significantly different (P > 0.05) and linear correlation existed between the two methods (P = 0.0001).
Conclusion:
It was reliable to determine the degree of root canal curvatures using the two methods.
