Abstract

Background and Objectives:

Two of the most critical factors affecting the prognosis of an avulsed tooth after replantation are extraoral dry time and the storage media in which the tooth is placed before treatment is rendered. The present study is undertaken to evaluate the periodontal ligament (PDL) cell viability after storage of teeth in different storage media, namely, coconut water, milk, and saline.

Materials and Methods:

Forty sound human premolars undergoing extraction for orthodontic purpose were selected. The teeth were allowed to lie dry on sand/mud for 30 min followed by which they were randomly divided and stored in three different media, i.e., coconut water, milk, and saline. After 45-min storage in their respective media, the root surface was then scraped for PDL tissue.

Results:

The ANOVA and Newman-Keuls post hoc procedure for statistical analysis of viable cell count under a light microscope using hemocytometer demonstrated that coconut water preserved significantly more PDL cells viable (P < 0.05) compared with milk and saline.

Conclusion:

Storage media help in preserving the viability of PDL cells when immediate replantation is not possible. This study evaluated the posttraumatic PDL cells' viability following storage in three different storage media. Within the parameters of this study, it was found that coconut water is the most effective media for maintaining the viability of PDL.
