Background and Aim: Application of varnish and dentin bonding agents can effectively reduce microleakage under amalgam restorations. Also rebonding may show some effects on microleakage and its compli...
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...
