What causes sequestrum bone?

There are three common causes to sequestrum formation; most commonly in cattle, a sequestrum is formed following a sharp trauma to the leg exposing the cortical bone and creating an ischemic zone that gets contaminated; a hematogenous septic microthrombus lodges in the cortical bone inducing ischemia; or it is formed …

Will bone grow back after tooth extraction?

Normally, in conventional extraction sockets, the bone grows back on its own once the tooth is removed. Growth can be enhanced by adding bone to the site at the time of the extraction.
