Abstract

Background and Objectives: One of the common materials as a root-end filling is MINERAL TRIOXIDE AGGREGATE ( MTA) that has various uses in endodontic. The aim of this study was to compare the micro leakage of white MTA in three diffrernt thicknesses as root –end filling materials.Materials and Methods: Seventy extracted human maxillary anterior teeth were randomly divided into 3 experimental groups each containing 20 teeth and 2 groups each containing 5 teeth used as positive and negative control groups. The root canals of the teeth were cleaned, shaped and obturated with gutta percha and AH-plus sealer .The apical 3 mm of each root was removed perpendicular to the long axis of the tooth using a diamond bur. In first, second and third experimental groups class I cavity in 1 mm, 2mm and 3 mm deep were prepared respectively and were restored with white MTA. In the positive and negative control groups, MTA was not used. All specimens were stored in synthetic tissue fluid for 48 hours .Then they were retrieved from this fluid and dried. Leakage was determined using a dye penetration method and observed with a stereomicroscope at a magnification level of 16. Accuracy of 0.1 mm was used for measurements. Data was analyzed using the ANOVA test at the 0.05 level of significance and Dunnett’s C for the comparison among groups.Results: Mean micro leakage in negative and positive control groups’ was zero and 3 millimeter respectively and in experimental groups were 0.4 mm, 0.2mm and 0.5mm for 1, 2 and 3 millimeter deep respectively. There was no significant difference among experimental and negative control groups (P>0.05) but differences were significant among experimental and positive control group (P=0.025).Conclusion: According to this in vitro study 1, 2 and 3 millimeter thicknesses of MTA can prevent leakage equally.
