Objectives: The purpose of this study was tocompare the ability of different cavity thickness ofBioaggragate to prevent microleakage usingcomputerized fluid filtration method.Materials and Methods: Fifty single- rootedhuman teeth were selected for this study. The rootcanals were prepared with Ni-Ti rotary files with5% Sodium hypocloride (NaOCl) solution as theirrigant. Then sealed with gutta-perchapoints(DiaDent®GuttaPercha Points, Seul, SouthCorea) and AH Plus (Dentsply Maillefer,Ballaigues, İsviçre). After root end resection, fiftytheeth were randomly selected into 1 of 4 testgroups containing 10 teeth each, and positive andnegative control groups containing 5 teeth each.Group 1: 1mm, Group 2: 2mm, Group 3: 3mm,Group 4: 6mm cavity thickness. And then allprepared root-end cavities filled with Bioaggregate.Leakage was evaluated using with a computarizedfluid filtration model.Results: Statistical analysis showed that group1 leaked more than all other groups (p<0.001).There was a significant difference between group 1and group 3(p<0.001),and also there was asignificant difference between group 2 and group 3.In contrast there was no significant differencebetween group 3 and group 4 (p>0.001).Conclusions: According to this study, thethickness of root end cavity must be minimum 3mm and more when Bioaggregate root end fillingmaterial is used.
