The search still continues to find the best storage media for avulsed teeth. Unfortunately, some of the recommended storage solutions are not commonly found in households or do not preserve the periodontal ligament (PDL) cells long-term. The purpose of the present study was to determine whether Pedialyte is a viable alternative storage solution for avulsed teeth by assessing its ability to preserve human PDL cell viability.
Human PDL cells were exposed to 6 different storage solutions (minimal essential medium [MEMα], Hank's balanced salt solution [HBSS], non-fat milk, coconut water, Pedialyte, or tap water) for 2, 6, 24, or 48 hours at 4°C or 25°C. Cell viability was quantified immediately or 1 week after exposure. The effects of these storage solutions on PDL cell motility and bacterial proliferation were also examined. The results were statistically analyzed by analysis of variance.
Pedialyte at 4°C and 25°C showed significantly (P < .001) higher cell survival compared with water after all time intervals. No significant difference was noted between control (MEMα), HBSS, coconut water, and Pedialyte at 4°C after 2 hours. Cells stored in Pedialyte for 24 hours at 25°C and assayed 1 week later showed significantly higher cell survivability compared with milk. Pedialyte supported significantly less bacterial growth compared with non-fat milk and coconut water. No difference in cell motility was observed for cells stored for 24 hours in Pedialyte, MEMα, HBSS, milk, or coconut water.
Pedialyte is a viable alternative as a storage solution for avulsed teeth.
目前仍在继续寻找最适合储存离体牙的储存介质。遗憾的是,一些推荐的储存解决方案在家庭中并不常见,或者不能长期保存牙周膜(PDL)细胞。本研究旨在通过评估其保存人牙周膜细胞活力的能力,确定Pedialyte 是否是离体牙储存的可行替代储存液。
将人牙周膜细胞暴露于 6 种不同的储存液(最低必需培养基[MEMα]、Hank's 平衡盐溶液[HBSS]、无脂牛奶、椰子水、Pedialyte 或自来水)中,4°C 或 25°C 下储存 2、6、24 或 48 小时。立即或暴露后 1 周检测细胞活力。还检查了这些储存液对 PDL 细胞迁移和细菌增殖的影响。通过方差分析对结果进行了统计学分析。
4°C 和 25°C 下的 Pedialyte 与所有时间间隔后的水相比,细胞存活率显著(P <.001)更高。在 2 小时时,4°C 下对照(MEMα)、HBSS、椰子水和 Pedialyte 之间没有显着差异。25°C 下储存 24 小时后,在 1 周后检测到的细胞存活能力明显高于牛奶。与无脂牛奶和椰子水相比,Pedialyte 支持的细菌生长明显较少。在 Pedialyte、MEMα、HBSS、牛奶或椰子水中储存 24 小时的细胞的细胞迁移没有差异。
Pedialyte 是储存离体牙的可行替代储存液。
