LABORATORY COMPARISON OF MICROLEAKAGE OF IDEAL MAKOO AND TETRIC FLOW COMPOSITES USING TWO DENTIN ADHESIVES

Introduction This study evaluated the degree of microleakage of Ideal Makoo and Tetric Flow composites using two dentin adhesives of Scotch Bond Multipurpose (SBMP) and Excite. Materials &Methods Sixty premolar teeth were divided into four groups of 15 and class V cavity preparations were done in CEJ. Group 1 was restorated with SBMP and Ideal Makoo, Group II with SBMP and Tetric Flow, Group III with Excite and Ideal Makoo, and Group IV with Excite and Tetric Flow. Stereomicroscope (X40) was used to evaluate and dye penetration in occlusal and gingival margins.Chi Square test,Pearson’s correlation test and Fisher`s exact test were used for data analysis (α= 0.05). Results The degree of leakage was not in correspondence to the type of composite. 1-The degree of leakage was not in correspondence to the type of dentin adhesive. 2- In four groups, the degree of leakage in gingival wall was significantly more than occlusal wall. Conclusion The type of composite and dentin adhesive have no effect on degree of leakage. The important factor was the type of wall. It means that in class V restorations, gingival wall is always observed to have more microleakage than occlusal wall.
