Abstract

Root-end filling material plays important role to achieve good outcome in apical surgery cases. MTA is known to be material of choice for this procedure. However, the existence of material porosity and lack of flowability could affect its adaptation with previously prepared retrograde cavity. Hence, MTA porosity and flowability could be improved by using indirect ultrasonic placement technique. The objective of this study is to analyze the difference of manual and indirect ultrasonic placement technique towards interfacial layer formation in apical surgery simulation. Retrograde preparation of forty single rooted human's premolar teeth were performed after endodontic treatment and obturation. Modified MTA was placed using manual (n=20) and indirect ultrasonic placement technique (n=20). All specimens were immersed in Indian ink for 3x24 hours, grinded transversally on 0.25 mm, 0.5 mm, 1 mm section, and the score of microleakage was determined using stereo microscope with 63x magnification. Statistical analysis was done using Chi Square (p<0,05). Less microleakage scores was detected in indirect ultrasonic group (45%) compared to manual group (63.7%) with significant difference statistically. Indirect ultrasonic placement technique of modified MTA has shown superior result in terms of micro leakage compared to the manual placement technique.
