Abstract
-
The purpose of this study was to examine the viability of PDL cells in rat molars by using in vivo MTT assay, which was used to compare fast cryopreservation group by liquid nitrogen (-196℃) with 4℃ cold preservation group.A total of 74 Sprague-Dawley white female rats of 4 week-old with a body weight of 100 grams were used. The maxillary left and right, first and second molars were extracted as atraumatically as possible under ketamine anesthesia.Ten teeth of each group were divided as six experimental groups depending upon the preservation. Cryopreservation groups were Group 1 (5% DMSO 6% HES in F medium), Group 2 (10% DMSO in F medium), Group 3 (5% DMSO 6% HES in Viaspan®), Group 4 (10% DMSO in Viaspan®) which were cryopreserved for 1 week and cold preservation groups were Group 5 (F medium), Group 6 (Viaspan®) at 4℃ for 1 week. Immediate extraction group was used as a control. After preservation and thawing, the in vivo MTT assay was processed. Two way ANOVA and Duncan's Multiple Range Test was performed at the 95% level of confidence. Another 2 teeth of each group were treated as the same manner and frozen sections 10 µm thick for microscopic observation.The value of optical density obtained after in vivo MTT analysis was divided by the value of eosin staining for tissue volume standardization. Group 1, 2 had significantly higher optical density than Group 3 and 4 which had the lowest OD value. Group 6 had higher OD value than in Group 5 (P < 0.05). Histological findings of periodontal ligament cell, after being stained with MTT solution were consistent with the in vivo MTT assay results.In this study, the groups which were frozen with DMSO as a cryoprotectant and the groups with F medium showed the best results.
