Assembling of fluid filtration system for quantitative evaluation of microleakage in dental materials

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. 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. Our system was constructed successfully and functioned correctly. In this pilot study we found this system efficient for the evaluation of microleakage of dental materials
