Abstract
|
|
|
The purpose of this study was to evaluate the microleakage electrochemically using different retrograde filling materials, different root resection angle, and different cavity preparation instruments.
@ES Experimental groups :
@EN Group 1. No bevel, cavity preparation with ultrasonic instruments, amalgam filling
@ES The results were as follows :
@EN 1. The group with Super EBA cement filling showed the least marginal leakage from second to fourth day(p<0.05), there was no significant difference between the group with amalgam filling during eighth to eighteenth day(p>0.05), but after the
nineteenth day here was a higher marginal leakage than the group with amalgam filling(p<0.05).
