义齿粘合剂广泛用于增强义齿的固位。义齿粘合剂及其可沥滤成分被摄入，但关于义齿粘合剂生物学方面的报道很少。本研究调查了19种市售义齿粘合剂的生物学性能。通过琼脂覆盖技术评估粘合剂，并分析微生物污染和甲醛含量。在琼脂覆盖试验中，所有材料均引起严重的细胞毒性效应。沙氏葡萄糖琼脂用于培养真菌，胰蛋白胨大豆肉汤用于培养需氧菌，包括真菌。大多数测试样品显示微生物生长。甲醛测试显示，四种产品中存在大量甲醛，两种产品中存在少量甲醛。
Denture adhesives are extensively used to enhance retention of dentures. Denture adhesives and their leachable components are ingested, but reports on the biologic aspects of denture adhesives are scarce. This study investigated some biological properties of 19 commercially available denture adhesives. The adhesives were assessed by the agar overlay technique and analyzed for microbial contamination and formaldehyde content. In the agar overlay test, all of the materials caused severe cytotoxic effects. Sabouraud dextrose agar was used for cultivation of fungi and tryptone soya broth for cultivation of aerobes, including fungi. Most of the samples tested showed microbial growth. The formaldehyde test revealed the presence of substantial amounts in four products and minor amounts in two products.
