Use of an amniotic membrane as a novel barrier in a tooth with a questionable prognosis.

The chief goal of combination therapy using guided tissue regeneration along with bone grafts is to optimally and predictably regenerate the periodontal attachment apparatus. The evolution of regenerative therapy along with careful patient selection and treatment planning can have positive results even in cases which are not ideal. The present case report describes a tooth with a questionable prognosis treated successively by endodontic then periodontal therapy using an amniotic membrane along with a bone graft to treat an intrabony defect. The follow-up, 12 months later showed a resolution of the interradicular lesion and a radiographic bone fill.
