摘要: Abstract Previous studies have shown that toxic reactions to direct-bonding adhesives can be demonstrated both in animals and cell culture tests. These effects also been with other related dental materials. The purpose of this study was compare the relative toxicity a number common orthodontic determine, by means rapid, sensitive vitro agar overlay test, how their changed time subsequent polymerization. Various bonding materials were tested either immediately or at various times up 30 days after cells stained vital dye (neutral red), diameter area unstained, nonviable measured, results three tests per sample averaged analyzed Duncan's Multiple Range Tests. All found some cytotoxic effect mixing, activator components two “no-mix” exhibiting significantly higher (p
