- Abstract
Introduction: The objectives of this study were to determine the depth of microleakage of direct and indirect composite resin (CR) restoration in Class V erosion lesion. Materials and Methods: Fifty six extracted human premolar teeth were chosen and randomly divided into two groups of 28 samples each. A V-shaped cavity with the dimension of 4 mm mesiodistally, 3 mm occluso-ginvivally and 2 mm axial depth were prepared on the buccal surfaces. Group A was restored with direct CR technique (Filtek Z250, 3M, USA) and Group B with an indirect CR technique (Ceramage Cervical Shofu, Japan) and resin cement Panavia F (Kuraray, Japan) for cementation. The teeth were immersed in freshly extracted lemon juice (pH of 1.84) for 24 hours before it was washed and immersed in 2% methylene blue for another 24 hours. Teeth were longitudinally sectioned at the middle of restoration and the leakage was assessed under stereomicroscope (Leica, Germany). Results: The result showed that GA has statistically significant (p < 0.05) lesser microleakage depth only for coronal margin compared to GB. For ceramage cervical margin has statistically significant (p < 0.05) lesser microleakage depth than the coronal margin. However Mann-Whitney test showed that there was no statistically significance difference between the groups for cervical margin and also between cervical and coronal margins for GA. Conclusion: Direct CR restoration has lesser microleakage than indirect CR at coronal margin while the indirect CR restoration gave the lesser in cervical margin.
