Abstract
The purpose of this study was to analyze the relationship between linear and volumetric measurements of apical dye penetration in canals obturated by various kinds of methods.
The canals of 108 roots without crown were conventionally prepared and randomly assigned to four group.
The canals of group I a2 were obturated by lateral condensation with sealer, group II a2 by thermoplasticized low-temperature (70℃) gutta-percha with sealer, group III by Thermafil endodntic obturation with sealer and group IV by
injection-molded
thermop-lasticized guttapercha.
One mm of root apex was exposed to a 2% methylene blue solution at 37℃ for 10 days, and the quality of apical seals was assessed by measuring the leakage linearly and volumetrically.
@ES The obtained results were as follows:
@EN In linear measurements, group II showed significanty less leakage than group III, I and group III also showed less than group IV, but no statistically significant difference was demonstrated between the others.
In volumetric measurements, group II showed significantly less leakage than group I and II, and no significant differnce from group III.
There was a weak significant correlation between the linear measurement and the volumetric measurement (r=0.3391, P<0.001).
