For a better prognosis of an avulsed tooth, it is important to store it in an appropriate storage medium prior to replantation. The purpose of this study was to evaluate the ability of ice apples to preserve the viability of periodontal ligament (PDL) fibroblasts.
Periodontal ligament (PDL) fibroblasts were procured from the roots of healthy premolars and cultured in Dulbecco's Modified Eagle's Medium (DMEM). They were preserved with-ice apple water (IAW), 30 and 10% ice apple fruit pulp extract (IAFPE), DMEM, negative control without any agent, and positive control DMEM supplemented with fetal bovine serum (FBS). Culture plates were incubated with investigational media at 37°C for 1, 3, and 24 hours. Each experiment was repeated thrice. Assessment of cell viability was done using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide tetrazolium reduction (MTT) assay. After every test period, storage media was removed; 60 µL of MTT solution was added to each well and incubated for 3 hours at 37°C. The supernatant was aspirated and the formazan blue crystals formed were solubilized using dimethyl sulphoxide (DMSO) (100 µL). Optical density was measured at a wavelength of 490 nm. The effects of the test storage media at each time period were evaluated by a one-way analysis of variance (ANOVA) test, and this was followed by Tukey's multiple comparison tests ( < 0.05).
A total of 10% IAFPE demonstrated the maximum capacity to maintain PDL cell viability in all three test periods ( = 0.001). Among the different forms of ice apple used in this study, IAFPE showed better results as compared to IAW ( = 0.001).
Ice apple fruit pulp extract (IAFPE) at 10% concentration showed the maximum capacity to maintain PDL cell viability across all three test periods. Therefore, it can be considered a suitable alternative natural storage medium for avulsed teeth. However, further, more detailed studies are required in this field.

为了使脱位牙获得更好的预后,在再植前将其保存在合适的储存介质中非常重要。本研究的目的是评估冰苹果保存牙周膜(PDL)成纤维细胞活力的能力。
从健康前磨牙的牙根获取牙周膜成纤维细胞,并在杜氏改良 Eagle 培养基(DMEM)中培养。它们分别用冰苹果水(IAW)、30%和 10%的冰苹果果肉提取物(IAFPE)、DMEM、无任何试剂的阴性对照以及补充有胎牛血清(FBS)的阳性对照 DMEM 进行保存。将培养板与研究介质在 37°C 下孵育 1、3 和 24 小时。每个实验重复三次。使用 3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四氮唑溴盐四氮唑还原(MTT)法评估细胞活力。在每个测试期结束后,去除储存介质;向每个孔中加入 60 µL 的 MTT 溶液,并在 37°C 下孵育 3 小时。吸出上清液,使用二甲基亚砜(DMSO)(100 µL)溶解形成的甲瓒蓝晶体。在 490 nm 波长下测量光密度。通过单因素方差分析(ANOVA)测试评估每个时间段测试储存介质的效果,随后进行 Tukey 多重比较测试(<0.05)。
在所有三个测试期内,10%的 IAFPE 表现出维持 PDL 细胞活力的最大能力(=0.001)。在本研究中使用的不同形式的冰苹果中,与 IAW 相比,IAFPE 显示出更好的结果(=0.001)。
10%浓度的冰苹果果肉提取物(IAFPE)在所有三个测试期内均表现出维持 PDL 细胞活力的最大能力。因此,它可被视为脱位牙合适的替代天然储存介质。然而,该领域还需要进一步更详细的研究。
