Introduction:
There are several methods for evaluating microleakage in dentistry, for example dye or bacterial leakage, electro-chemical methods, radioisotope labeling and fluid filtration. The purpose of this study was to assemble the fluid filtration system for quantitative evaluation of microleakage in dental materials.
Materials And Methods:
The roots were connected to a tube filled with an underwater pressure supply. A bubble was introduced into the water to measure endodontic leakage. A digital camera and professional software were utilized to record and measure the bubble displacement.
Results:
Our system was constructed successfully and functioned correctly.
Conclusion:
In this pilot study we found this system efficient for the evaluation of microleakage of dental materials.
