effects of different storage media on the regeneration of pdl in experimentally avulsed teeth [histological and immuno-histochemical study]

ABSTRACT

The choice of storage medium for preserving the traumatically avulsed teeth is important for the success of future replantation. The objectives of this study were to evaluate the effectiveness of pre-replantation storage media on periodontal ligament healing. Extracted, fully-developed rat maxillary incisors were stored in milk, saline or tap water for 15 minutes. Teeth that had been stored in either cold milk or saline showed regeneration of typical PDL, while those stored in tap water showed signs of degeneration. The present study has showed that cold milk and saline may thus be rec-'ommended as storage medium for ex-articulated teeth prior to replantation in case when immediate replantation is not possible
