عنوان انگلیسی Influence of Storage Media pH and Time on Cervical Sealing Performance of Three Bonding Systems
چکیده انگلیسی مقاله Background and aim This study evaluated influence of pH of storage media and storage time on cervical sealing performance of three different bonding systems. The microleakage of three bonding systems) Scotchbond Mulit-purpose, Perma Quik PQ1 and Clearfil SE bond (over 7 days, 30 days and 90 days was investigated. Methods and Materials Two hundred and seventy class V wedge shape cavities were prepared in sound human premolars with coronal margins in enamel and cervical margins in dentin / cementum. Bonding systems were applied strictly according to manufactures instructions. Cavities were restored by Z100 resin composite. After finishing and polishing, teeth were randomly divided according to the storage medium and storage time to 27 groups (n=10).Specimens were coated with nail varnish, immersed in silver nitrate for 4 hours and sectioned longitudinally. The extend leakage was measured and ranked using a 0-3 scale. Results Statistical analysis using Kruskal-wallis test revealed significantly higher leakage scores (p< 0.05) for SBMP in 30 days according to the storage medium. And also statistical analysis using Kruskal-wallis test revealed significantly higher leakage scores (p< 0.05) for SBMP and SEB according to the storage time. Conclusion PQ1 and SEB showed the best outcomes in dentin/cementum when compared to SBMP according to the storage medium and storage time. Key words Microleakage. Dentin bonding, Storage time, pH.
