Comparison of Microleakage in Human and Bovine Substrates Using Confocal Microscopy
Microleakage Substrates Human teeth Bovine teeth
2010/1/21
Microleakage in human and bovine teeth was compared. Cavities were prepared on the buccal surface in 20 human and 20 bovine teeth (3mm×2mm in depth). The teeth were divided into 4 groups (n=10) accord...
