Summary

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.

Conditions

  • Alveolar Bone Loss

Interventions

PROCEDURE

Autogenous stored mineralized dentin graft (ASMDG)

Autogenous stored mineralized dentin graft (ASMDG) particles will be prepared by immersing tooth particles in basic ethanol for 10 min for disinfection, then washed twice in saline and dried using sterile gauze. The disinfected particles will then be stored at room temperature for 21 days in a sterile container. After 21 days, a second extraction will be performed followed by mixing the stored graft with a few drops of sterile saline to be packed in a socket after extraction

PROCEDURE

Autogenous fresh mineralized dentin graft (AFMDG)

Autogenous fresh mineralized dentin graft (AFMDG) particles will be prepared by immersing tooth particles in basic ethanol for 10 min for disinfection, then washed twice in saline and dried using sterile gauze.
