Background: The sealing ability of temporary restorative material is an important parameter for the success of endodontic therapy. Cavit-G and IRM have been widely used for the same purpose. A novel material Orafil- LC, light cured resin based material, has been recently introduced for sealing the access preparations and preventing the microbial re-colonization of root canal system.
Aim: To compare the coronal sealing ability of Cavit G, IRM and Orafil-LC by means of methylene blue dye penetration method.
Methodology: The root canals of fifety mandibular premolars were prepared with Ni-Ti rotary instruments under irrigation with 5% NaOCl and 17% EDTA. Samples were obturated and divided into three experimental and two control groups. All three materials were manipulated according to manufacturer instructions and placed into 4mm deep access cavities. Samples were incubated, thermocycled and then placed in 2 % methylene blue dye for one week. Samples were sectioned bucco-lingually and viewed under stereomicroscope. Degree of dye penetration was evaluated and scored for each group.
Results: Data from each group was compared using one way ANOVA and post hoc Tukey test (P<0.05). Cavit and Orafil-LC showed significantly lower dye leakage than IRM. Conclusion: Cavit and Orafil-LC have better coronal sealing ability than IRM
