Abstract
INTRODUCTION: Dentoalveolar trauma is a very common and avulsion is the most frequent injury. Treatment of choice following avulsion is immediate reimplantation. However, in cases where this might not be possible the prognosis of reimplanted teeth can be improved by the selection of an appropriate storage media. Prevention of ankylosis and replacement resorption depends more on the potential of storage media to maintain cell viability rather than the extraalveolar time period. AIM: To compare and evaluate the efficacy of different storage media in maintaining the viability of Periodontal Ligament (PDL) cells in an avulsed tooth. MATERIALS AND METHODS: A total of 58 freshly extracted human premolar teeth were divided into four experimental groups and two control groups. The positive and negative controls corresponded to 0 minute and an eight hours dry time, respectively. The experimental teeth were stored dry for 30 minutes and then immersed in one of the four media: Hank's Balanced Salt Solution (HBSS), coconut water, aloe vera and saline for 45 minutes. The teeth were then treated with Collagenase Type II and Dispase for 30 minutes. The number of viable PDL cells were counted with a haemocytometer and analysed. The statistical analysis was done using SPSS version 15.0. The Analysis of Variance (ANOVA) and Post-hoc tests (Tukey-HSD) were performed to reveal the statistical significance. The values were represented in number (%) and mean±SD. RESULTS: Statistical analysis demonstrated that among the experimental groups maximum percentage of viable cells were seen in HBSS (87.33%) followed by coconut water (79.87%), aloe vera (70.59%) and saline (50.56%). CONCLUSION: Within the parameters of this study, it can be concluded that the HBSS is the most effective storage media in maintaining the viability of PDL cells. However, in Indian scenario where availability of HBSS is questionable, coconut water can be considered as the best natural storage media for an avulsed tooth followed by aloe vera.
