A Comparative Evaluation of Shear Bond Strength of Resin-modified Glass Ionomer and Zirconomer Incorporated with 1.5% Doxycycline: An In Vitro Study
Journal Title: Indian Journal of Dental Advancements - Year 2017, Vol 9, Issue 3
Abstract
Context: Dental caries are the most pervasive microbiological disease in the world. To overcome this, various restorative materials were introduced. However, secondary caries have been quoted as one of the most common causes of restoration failures. Following the bacterial attack, a group of enzymes called matrix metalloproteinases (MMPs) are engaged with the degradation of the dentinal matrix. The use of tetracyclines and their derivatives with restorative could contribute to inactivate MMPs and arrest caries progression. Aim: The purpose of the present in vitro study was to evaluate the shear bond strength of resin-modified glass ionomer cement (RMGIC) and Zirconomer incorporated with 1.5% Doxycycline. Materials and Methods: Forty freshly extracted human molars without any defects were collected. The teeth were mounted in plastic rings of 1-inch diameter with cold cure acrylic resin, and the occlusal surfaces were ground flat using a diamond disc with a water coolant at slow speed to expose the dentin. The specimens were then divided into two groups with 20 specimens in each group according to the restorative material used. The restorative materials were mixed with 1.5% Doxycycline, condensed into cylindrically shaped plastic tubes with an internal diameter of 3 mm and a height of 4 mm. In Group A, the samples were light cured for 40 s. Shear bond strength of all the samples was tested under the universal testing machine. Statistical Analysis: The results were compared using unpaired “ t ”-test to detect significance between groups using SPSS 17.0 software. Results: Statistical analysis showed that RMGIC with 1.5% Doxycycline shows highest shear bond strength ( P < 0.05) when compared to Zirconomer with 1.5% Doxycycline. Conclusion: RMGIC with 1.5% Doxycycline showed highest shear bond strength when compared to Zirconomer with 1.5% Doxycycline.
