The purpose of this study was to evaluate microleakage of etched and non-etched amalgam restorations lined with dentin bonding system primer and adhesives.
Class V amalgam preparations were made in 100 extracted human premolars divided into 10 groups with 10 teeth each. SEM was taken to assess the dentin/amalgam interface.
The results were as follows
1. At the occlusal and gingival margins, all experimental groups showed lower leakage value than unlined group(p(0.05). The Copalite¢ç-lined group showed higher leakage value than other experimental groups(p<0.05).
2. In all experimental groups, the gingival margin showed higher leakage value than the occlusal margin.
3. There were no significant difference between non-etchiirg and etching groups, primer only and primer & ad¡©hesive groups, primer & adhesive and self priming adhesive groups(p)0.05).
4. On the SEM observation, continuous gaps were observed in the unlined and Copalite lined groups, but the gaps were filled with primer or adhesive layer in other experimental groups.
