Abstract

One of the problems concerning restorative dental materials is MICROLEAKAGE that leads to unfavorable consequences in dental restorations. In order to evaluate the MICROLEAKAGE in different materials' laboratory studies are needed. Usually human specimens are used in laboratory, but since providing the human specimen are very difficult and time consuming and also there is the risk of AIDS and HEPATITIS in this case, it is better to substitute human specimen. BOVINE TEETH have been used extensively in many studies. In this study we compared, the micro leakage between human and BOVINE TEETH. In this study 10 human anterior permanent teeth and 10 bovine anterior permanent teeth were selected and class V cavities on buccal and lingual surfaces were prepared. The cavities were filled with composite and the specimen was thermocyled for 500 times. After storing the specimens in fuschin for 24 hours and sectioning them from the middle, they were scanned under stereomicrosope. The results showed that the amount of micro leakage in enamal was Zero but in dentin higher than that of enamal in both of the specimens. Also the gingival margins on the buccal surface of the BOVINE TEETH had same amount of micro leakage in the same sw1ace in human teeth. But, the gingival margin on the lingual surface in BOVINE TEETH had less MICROLEAKAGE compared to the some surface in human teeth. In the base of this study permanent anterior BOVINE TEETH could be an acceptable substitute for human teeth in miroleakage studies. Of course more ex1ensiveinvestigations are needed to complete these studies.
