Abstract

AIM

AIM of this study is to evaluate the influence of critical diameter of apical foramen and file size using propex pixi apex locator in working length determination.

MATERIALS AND METHODS

In this study, ten single rooted teeth were selected. They were decoronated at cemento enamel junction. After determining the actual working length, they were embedded in alginate mold. Foramina were widened from 0.6mm to 0.8mm. The measurements were taken with electronic apex locator propex pixi with files from sizes 10 K to respective sizes. Statistical accuracy of propex pixi was calculated by using Anova test for different diameters and for the influence of file size.

RESULTS

RESULTS showed that propex pixi apex locator was accurate when foramen diameter is 0.6 (60k file size), its accuracy diminished with increased foramen diameter

CONCLUSION

Propex pixi is accurate for foramen diameter of 0.6mm, independent of file size. Its accuracy decreases as apical foramen widens, so care should be taken when using clinically.

摘要

目的

本研究的目的是评估使用Propex Pixi根尖定位仪时根尖孔临界直径和锉的尺寸对工作长度测定的影响。

材料与方法

本研究选取了10颗单根牙。在牙骨质釉质界处去除牙冠。确定实际工作长度后，将其嵌入藻酸盐模型中。将根尖孔从0.6mm扩大到0.8mm。使用电子根尖定位仪Propex Pixi，用从10 K号到相应尺寸的锉进行测量。通过方差分析计算Propex Pixi对于不同直径以及锉尺寸影响的统计准确性。

结果

结果显示，当根尖孔直径为0.6（60k锉尺寸）时，Propex Pixi根尖定位仪是准确的，其准确性随着根尖孔直径的增加而降低。

结论

Propex Pixi对于0.6mm的根尖孔直径是准确的，与锉的尺寸无关。随着根尖孔变宽，其准确性降低，因此临床使用时应谨慎。
