The Comparative Analysis of the Effectiveness of Four Different Storage Media (Placentrex, Propolis 10%, Pomegranate Juice 5%, and Hank's Balanced Salt Solution) in Preserving the Viability of Periodontal Ligament Cells: An In Vitro Study.

Abstract

Out of all traumas, dentoalveolar trauma occurs quite frequently and is commonly linked to avulsion injuries. Of all severe lesions to the permanent dentition, tooth avulsion accounts for 1%-16% of cases. The extraoral dry time and the storage medium in which the tooth is stored and its capacity to promote cell viability are two important variables influencing the prognosis of an avulsed tooth following replantation. The aim of this paper is to assess and contrast the effectiveness of placentrex, propolis 10%, pomegranate juice 5%, and Hank's balanced salt solution (HBSS) as a storage medium in preserving the periodontal ligament (PDL) cells' viability. Sixty freshly extracted premolars were put in four various media for 45 minutes each, including HBSS, placentrex, propolis 10%, and pomegranate juice 5%, and placed in an incubator for 30 minutes in 15 mL falcon tubes with 2.5 mL solutions of collagenase 0.2 mg/mL and dispase 2.4 mg/mL in phosphate-buffered saline. Bovine serum was added after incubation, and the mixture was centrifuged for four minutes. Trypan blue 0.4% wasused to identify the cells. Under a light microscope, a hemocytometerwasutilized to quantify the number of periodontal ligament cells that were still alive. Propolis, pomegranate, and placentrex are all significantly inferior to HBSS in the context of the sustainability of the cells. It was discovered that HBSS with placentrex and pomegranate juice 5% was statistically insignificant. The difference in periodontal ligament cell viability between propolis 10%, HBSS, placentrex, and pomegranate juice 5% was shown to be statistically significant. When compared to other media such as propolis 10% and pomegranate juice 5%, placentrex is a better alternative storage medium for avulsed teeth.
