根管冲洗液对RAYPEX 6及PROPEX Ⅱ电子根尖定位仪测量准确性的影响
The influence of root canal irrigation on the accuracy of RAYPEX 6 and PROPEX Ⅱ electronic apex locator
摘要
Abstract
Objective:To investigate the influence of three kinds of root canal irrigations on the accuracy of RAYPEX 6 and PROPEX Ⅱ electronic apex locator.Methods:RAYPEX 6 and PROPEX Ⅱ were selected as electronic apex locators.The root canal length of 40 extracted teeth with single straight root canal was measured in the case of 5.25%NaClO,0.9%NaCl and 3% H2O2.The difference between the electronic length and actual length was calculated.Statistic software SPSS 22.0 was used to assess the accuracy by the method of independent sample t test.Results:All mean difference value of these two electronic apex locators were less than 0.5 mm.There was no statistically significant difference between the two locators by using 0.9%NaCl(P>0.05).There was statistically significant difference in the case of 5.25%NaClO and 3% H2O2,respetively(P<0.05).Conclusion:Different types of root canal irrigation influenced the accuracy of RAYPEX 6 and PROPEX Ⅱ electronic apex locator,but the accuracy was still able to meet the requirements of clinical root canal length measurement.关键词
