An In Vitro Investigation of Microleakage of Bonding Agent Treated C1-I Amalgam Fillings

Marginal leakage was investigated in vitro on C1-I amalgam fillings, placed alone and placed with two different bonding agents (Adaptabond, Heliobond). Teeth were immersed in 2% basic fuchsin dye solution, after thermal cycling. Dye penetration degree was evaluated according to the index suggested by Going. Results was significantly better in experimental groups than control group. Bonding agents were found effective in reducing micro leakage around the margins of amalgam restorations.
