Aim: The aim of the study was to construct a novel fluid filtration model and analyse the working of the model for the quantitative evaluation of microleakage. Materials and Methods: An oxygen cylinder equipped with pressure adjusting device was connected to a pressurised buffer system, which was then connected to micropipette and a three-way control faucet, the faucet holds attachment for syringe at the upper portion and the tooth sample at the lower part. A tooth sample with perforation condensed with Gutta percha and without perforation was connected to the fluid filtration model, to ensure bubble displacement a bubble was introduced in micropipette. A digital SLR camera was used to record the bubble displacement, AutoCAD Software for the measurement and custom made software for calculation of microleakage. Results: The model was constructed and functioned successfully. Conclusion: This model can be used for the evaluation of microleakage of dental materials.
