The purpose of the present study was to compare the cytotoxicity of Reso-Pac and Coe-Pak periodontal dressing.
According to ISO-10993-12:2012, 1-, 3- and 7-day extracts of the two periodontal dressings were prepared in cell culture medium and exposed to the two cultured cell lines. Cell viability and proliferation at 24 h and 72 h following exposure were evaluated using quantitative MTT assay.
The results showed a significant (P < 0.05) reduction in the viability of cells exposed to the 3- and 7-day Coe-Pak extracts at 24 h and 72 h compared to the control group (no exposure to the extract). Reso-Pac extracts slightly decreased cell viability compared to the control group. Understudy materials showed greater cytotoxicity against human osteoblast-like compared to the human gingival fibroblast cells. No significant (P > 0.05) difference was found in the viability of cells exposed to undiluted (100%) one-day extract and diluted (50%) extract of both understudy materials at 24 h and 72 h after exposure.
Based on the results, Reso-Pac periodontal dressing has less cytotoxicity than Coe-Pak.
本研究旨在比较Reso - Pac和Coe - Pak牙周敷料的细胞毒性。
根据ISO - 10993 - 12:2012标准,在细胞培养基中制备两种牙周敷料的1天、3天和7天提取物,并将其作用于两种培养的细胞系。使用定量MTT法评估暴露后24小时和72小时的细胞活力和增殖情况。
结果显示,与对照组(未暴露于提取物)相比,暴露于Coe - Pak 3天和7天提取物的细胞在24小时和72小时时活力显著降低(P < 0.05)。与对照组相比,Reso - Pac提取物使细胞活力略有下降。与人类牙龈成纤维细胞相比,受试材料对人成骨样细胞显示出更大的细胞毒性。在暴露后24小时和72小时,暴露于受试材料未稀释(100%)的1天提取物和稀释(50%)提取物的细胞活力未发现显著差异(P > 0.05)。
基于结果,Reso - Pac牙周敷料的细胞毒性低于Coe - Pak。
