MICROLEAKAGE EVALUATION OF MODIFIED MINERAL TRIOXIDE AGGREGATE EFFECT TOWARD MARGINAL ADAPTATION ON CERVICAL DENTIN PERFORATION
Keywords:Perforation, Mineral trioxide aggregate, Modified mineral trioxide aggregate, Microleakage, Marginal adaptation
Objective: To analyze the marginal adaptation of conventional MTA (ProRootÂ®MTA) and modified MTA (MTA Flowâ„¢) on perforated dentin.
Methods: Forty specimens of human's premolar teeth with lateral perforations were sealed by conventional MTA (n=20) and modified MTA (n=20). After 24 hours, the specimens were immersed in Indian ink for 24 hours, then embedded in resin and sectioned longitudinally in mesial-distal direction. The score of microleakage was determined using stereo microscope (SteREO Discovery. V12, Carl Zeiss) with 20x magnification. Statistical analysis was done by Chi Square (p<0,05).
Results: Less microleakage score (0,5-1mm) was detected in modified MTA (25%) compared to conventional MTA (45%), although not statistically significant.
Conclusion: Microleakage were detected in both conventional and modified MTA as material for cervical dentin perforation treatment, although modified-MTA group showed less microleakage score.
