Abstract:
:Different types of storage media have been studied for use in the replantation of exarticulated teeth. It was found that human periodontal ligament cells survived well in milk. Fifty percent of the cells were viable after 12 hours' storage in milk, while no cells were viable after three hours' storage in saliva. Brief storage in saliva followed by subsequent storage in milk was better than storage in saliva only.

Earlier observation of the negative effect of a high-sucrose diet on a parotid function involved in the control of intradentinal solute movement led us to hypothesize that parotid gland ...
