摘要: This study investigated the cytotoxicity of crystal-coloured orthodontic elastomeric ligatures polyurethane. Six from distinct manufactures were divided into 6 groups 10 elastics each: Groups P1, P2, P3, P4, P5 and P6 (Polyurethane). The essay was performed using L-929 line cells, which submitted to cell viability test with neutral red (“dye-uptake”) at time intervals 1, 2, 3, 7 28 days. Analysis variance (ANOVA) multiple comparisons Tukey’s used (p < .05). There statistical differences .05) in between P2 1 2 All considered suitable for clinical use. hypothesis accepted, elastomers processing route injection molding these showed lowest viability, due temperature pressure elastomers.
