“…Although immediate replantation has been shown to have the best prognosis (12, 14–18), unfortunately, this rarely occurs. When immediate replantation of an exarticulated tooth is not possible, the storage conditions should be designed to maximize preservation of the PDL during transportation to the dental office (19).…”

Many solutions have been examined as possible storage media for avulsed teeth. In this report, human periodontal ligament (PDL) cells were exposed for 1 h to culture medium, milk, Hanks Balanced Salt Solution (HBSS), Soft Wear, Opti Free, and Solo Care contact lens solutions, Gatorade, and tap water, at room temperature and on ice. The number of viable cells was counted using the trypan blue exclusion technique, immediately after exposure (0 h) and at 24 and 48 h, to test the proliferative capacity of the cells after treatment. The results indicated that a significantly higher number of cells survived and proliferated when the exposures were performed at 0 degrees C. Water had a detrimental effect on the cells, whereas culture medium and HBSS preserved significantly more viable cells than the other experimental solutions. Within the parameters of this study, it appears that HBSS is the optimal storage medium for avulsed teeth. Low-fat milk could serve as an alternative if ice is available. Contact lens solutions or Gatorade on ice could serve as short-term (1 h) storage media if the other solutions are not readily available.

“…Minor animals, such as mice (12), rats (13-15) and hamsters (16)(17)(18)(19)(20)(21)(22) have been used for replantation studies. However, their diminutive dentition presents a serious obstacle, espeeially when endodontic therapy is a part of the experimental proeedure.…”

Experimental dental traumatology: development of a model for external root resorption

Intentional replantation of teeth appears to be a suitable model for examining the etiology and pathogenesis of root resorption elicited after traumatic dental injury. A histomorphometric analysis of root resorption developed with this model is described. An analysis of the accuracy and precision of the method in replanted monkey incisors has demonstrated that the method is usually reliable in revealing the extent and type of root resorption. In some experimental circumstances, however, where the pulp status was not controlled by endodontic therapy, a large intra‐ and interanimal variation was found in the extent of root resorption. Apart from a relation to tooth maturation and tooth type (incisors versus molars), this variation was primarily caused by haphazard occurrence and extent of inflammatory resorption. Based on an analysis of a series of experimental replantation studies, the following guidelines for experimental design seem appropriate: 1) selection of teeth according to identical tooth development and pulp status (i.e. intact, extirpated or root‐canal‐treated); 2) use of a standardized extraction procedure; 3) consideration of the type of teeth included (i.e. molars vs. incisors), unless paired experiments are planned or the experimental design includes an equal number of incisors and molars allotted to the different experimental groups; 4) side differences (right vs. left side) are apparently of no or minor importance; 5) sex differences are apparently of no or minor importance; 6) an individual proneness to resorption is apparently of no or minor importance, which means that more than one tooth can be used in each animal. The experimental design thus does not dictate the use of paired (i.e. homologous) teeth. However, as a matter of safety, when small differences in healing are expected, paired observations should be used.
