Introduction.
The aim of this study was to compare the coronal seal of different thicknesses of MTA with gutta-percha after post space preparation.
Materials and Methods.
A total of 50 maxillary central incisors randomly divided into 5 experimental groups ( n = 8 ).
After preparation of the root canals with step back technique, in groups 1 and 2, post spaces were prepared and 4 or 5 mm gutta-percha remained in the apical, respectively.
In groups 3, 4, and 5, there was 1-2 and 3 mm MTA in the apical, respectively.
The ten teeth serve as control groups.
The teeth were connected to a bacterial microleakage evaluation system.
The study period was 120 days and the samples were evaluated on ten-day intervals; Meier-Kaplan technique was used for estimation of the mean time of microleakage to occur.
Log-rank test was used for comparison of microleakage.
Results.
Number of samples exhibiting microleakage in MTA was less than those of gutta-percha at all intervals.
Means of days with no microleakage were maximum and minimum with 3 mm MTA and 4 mm gutta-percha, respectively.
Conclusion.
Obturation of root canals using the MTA technique provides a proper seal with the minimum thickness of MTA in teeth requiring post space preparation.
