Periodontal Ligament Fibroblast Cell Viability Following Treatment with Different Concentrations of Green Tea, Aloe Vera and a Mixture of their Extracts

Abstract

Objectives: Various studies have identified green tea and Aloe vera as a suitable medium for avulsed teeth. The aim of this study was to evaluate and compare the viability of periodontal ligament (PDL) fibroblasts following treatment with the extracts of these two plants and their mixture.
 Materials and Methods: Human PDL fibroblasts were purchased and treated with different concentrations of Aloe vera, green tea, and a combination of these two extracts. Hank’s balanced salt solution and culture medium were employed as positive and negative controls, respectively. Viability was assessed using the MTT assay. Two-way ANOVA and post-hoc tests were used for statistical analysis (P<0.05).
 Results: There was a significant difference in PDL fibroblast viability between different concentrations of the extracts. Higher concentrations of green tea and the combination of the two extracts significantly increased cell viability. Higher concentrations of Aloe vera had the least positive effect on maintaining the viability of these cells.
 Conclusion: If confirmed by further studies, the combination of Aloe vera and green tea extracts might be considered as a suitable media for different purposes like storing avulsed teeth.

A literature review of bioactive substances for the treatment of periodontitis: In vitro, in vivo and clinical studies

“…Transplant of GMSCs inhibited the loss of alveolar bone induced by periodontitis and enhanced formation of new alveolar bone. Moreover, previous studies have reported that the conditioned medium of periodontal ligament-derived mesenchymal stem cells (PDLSCs) enhanced periodontal tissue regeneration, but isolating PDLSCs is difficult and requires multiple periodontal membranes from extracted teeth [ 232 , 233 ]. To provide an alternative to PDLSCs, a study investigated whether the conditioned medium from GMSCs (GMSC-CM) exhibited an effect similar to that of the conditioned medium of periodontal ligament-derived mesenchymal stem cells [ 234 ].…”

Cytotoxic Effect of Tideglusib on Human Fibroblasts: An In Vitro Study

“…26 Studying fibroblast responses to Tideglusib may give light on the drug's potential impacts on dentin-pulp complex regeneration and periodontal tissue health. 27 Furthermore, the use of fibroblasts in this study aligns with the goal of assessing Tideglusib biocompatibility and possible functions in promoting or inhibiting tissue regeneration in the oral environment.…”

Effectiveness of mixed tea plant extract gel with chitosan on fibroblast cells after tooth extraction of Wistar rats

“…7 The content of green tea, namely flavonoids, plays an important role in the healing process such as antiinflammatory and increasing the number of fibroblasts. 8 Natural ingredients derived from shrimp shells, namely chitosan, in the wound healing process can stimulate tissue regeneration, activate inflammatory cells such as fibroblasts, and remodeling process during the wound healing process. 9 In vivo research conducted by Qin et al, chitosan provides a non-protein matrix during tissue growth, assists in natural clotting, and blocks nerve endings to reduce pain.…”
