INTRODUCTION: Histidine-tryptophan-ketoglutarate (HTK) is a preservation solution used for organ transplantation. The physiological pH and osmolality of this solution are known to facilitate cell proliferation and cell membrane stabilization. The purpose of the present study was to investigate the efficacy of several concentrations of HTK solution as a storage medium for avulsed teeth.
METHODS: Cultured human periodontal ligament cells were stored in different concentrations of HTK solutions. After 1, 3, 6, 12, 24, 48, and 72 hours, cell viability was assessed using the Cell-Counting Kit-8 (Dojindo Molecular Technologies, Kumamoto, Japan) and LIVE/DEAD (Invitrogen, Carlsbad, CA) assay. Cell response of the most effective concentrations of HTK solution were further analyzed by gene expression profiling, and their cell viability was compared with other storage media.
RESULTS: The highest cell viability was observed in 50% HTK solution in various concentrations of HTK solution (P < .05). In periodontal ligament cells stored in 50% HTK solution for 3 hours, the expression of genes related to angiogenesis, the inflammatory response, and cell proliferation was increased compared with the control. Compared with other storage media, the highest cell viability was observed in 50% HTK solution.
CONCLUSIONS: Our study suggests that 50% HTK solution containing cell culture medium represents a suitable storage medium for avulsed teeth.
