Tooth extraction triggers a cascade of biological events mediated by both the local inflammatory response that follows the surgical intervention and the deprivation of masticatory stimulation of the periodontium, which elicit an alteration of the homoeostasis and structural integrity of the periodontal tissues. Bone remodeling kicks off after tooth loss and continues for several months with most changes taking place in the first three months. Interestingly, Schmidt-Schultz and Schultz, found that intact growth factors are conserved even in the collagenous extracellular matrix of ancient human bone and teeth. Thus, the application of stored dentin may have similar benefits as fresh dentin, preserving intact growth factors for a prolonged period avoiding the need to perform multiple surgical interventions simultaneously. The volume of the particulate dentin is more than twice of the original root volume. Thus, the idea of using autogenous stored mineralized dentin grafts (ASMDG) in ARP evolved.
