AIM
THE AIM OF THE PRESENT STUDY IS TO EVALUATE AND TO COMPARE THE ACCURACY OF TWO ELECTRONIC APEX LOCATORS (EALS): DentaPort ZX and iPex, at a position 0.5 mm short of the apical foramen.
MATERIALS AND METHODS
Thirty single-rooted, mandibular premolar teeth were selected. Standard access cavities were prepared and the actual length (AL) was calculated. The samples were then embedded in alginate and the electronic measurements were determined and recorded.
RESULTS
The results obtained showed that in determining the root canal length with a tolerance level of ±0.5 mm, i.e., AL ± 0.5 mm, DentaPort ZX was accurate in 93.3% of the samples and iPex was accurate in 90% of the samples at a position 0.5 mm short of the apical foramen.
CONCLUSION
A strong correlation was seen between the two electronic methods and AL and also in between the two EALs, showing the possibility of their use to measure the root canal length. No statistically significant difference was found between both the apex locators.
目的
本研究的目的是评估和比较两种电子根尖定位仪（EALS）：DentaPort ZX和iPex在距离根尖孔0.5毫米处的准确性。
材料与方法
选择30颗单根下颌前磨牙。制备标准的开髓洞形并计算实际长度（AL）。然后将样本嵌入藻酸盐中，进行电子测量并记录。
结果
所得结果表明，在以±0.5毫米的公差水平确定根管长度，即AL±0.5毫米时，DentaPort ZX在距离根尖孔0.5毫米处对93.3%的样本测量准确，iPex对90%的样本测量准确。
结论
两种电子方法与AL之间以及两种EAL之间均存在强相关性，表明它们可用于测量根管长度。两种根尖定位仪之间未发现统计学上的显著差异。
