Abstract

Dental trauma resulting in permanent tooth avulsion commonly affects the young population. The prognosis of replantation after avulsion depends on the natural history of inflammatory and replacement resorption. Several risk factors for type and onset of external resorption have been defined. This case study describes different resorptive patterns observed in two upper central incisors belonging to a single individual, avulsed in the same moment, and replanted after thirty-six hours of dry storage. The roots were analyzed by scanning electron microscopy and stereomicroscope imaging, to obtain an in-depth analysis of the resorptive pattern. The aim of this report is to: (i) underline the high variability in the incidence of root resorption after replantation across and within types of teeth and resorption; and (ii) underline the possible concurrence of different factors affecting the onset and type of resorptive pattern. In conclusion, an unpredictable pattern of resorption may account for the poor prognosis when teeth are replanted outside the current recommendations.
