Establishment of allograft tooth transplantation model. a Schematic diagram of the model. b Micro-CT image of the control group (b1, b3) and the allograft group (b2, b4). The roots of the allograft group showed tooth absorption (b2, b4). c, d Representative H&E staining of control (c) and allograft group (d). During the restoration of teeth after transplantation, the PDL partially reattached to the cementum surface (d2), part of the samples accompanied by pulp necrosis and root resorption (d3, d4). The black arrows point to the PDL near the crown in c2 and d2, the PDL at the root furcation in c3 and d3, and the PDL of the root apex in c4 and d4. c2-c4 are magnified views of the c1 dotted areas, d2-d4 are magnified views of the d1 dotted areas
