Treatment of endodontic perforations using guided tissue regeneration and demineralized freeze-dried bone allograft: two case reports with 2-4 year post-surgical evaluations.
Clinicians often have difficulty with the diagnosis and treatment of root perforation. This paper reports two patients with root perforation treated with periodontal surgery associated with guided tissue regeneration (GTR) and demineralized freeze-dried bone allograft (DFDBA). This combined treatment resulted in minimal probing depths, minimal attachment loss, and radiographic evidence of bone gain after follow-up evaluations that ranged from 2 to 4 years. These case reports show a correct diagnosis and removal of etiologic factors can restore both periodontal and endodontic health.
