Abstract
The present study was conducted to evaluate and compare clinically, radiographically and densitornetrically autogenous periosteal graft and EpiGuide bioresorbable polylactic acid membrane in the management of class
II furcation defects
A total number of ten chronic periodontitis patients participated in this study and twenty bilateral class II furcation defects with almost the same defect size were selected.
The defects were randomly assigned to one of the following groups:
Group I: ten class II furcation defects were managed by full thickness flap and Epi-Guide membrane.
- Full thickness mucoperiosteal flaps were reflected and carefully elevated.
- The surgical site was debrided and root surfaces were scaled and planed.
- The Epi-Guide membrane material was trimmed with a scissors or scalpel to adequately cover the defect.
- The membrane was adapted carefully to cover the furcation defect completely.
- The membrane was secured with 5-0 chromic catgut suture.
- Flaps were repositioned and sutured using 4-0 silk suture.
- The wound was covered by periodontal dressing.
Group 11: ten class II furcation defects were managed by full thickness flap and periosteal membrane.
- Full thickness mucoperiosteal flap with a sulcular incision were elevated over each furcation aid granulation tissue removed.
- The inner surface of the flap was curetted to remove epithelium and granulation tissue root surface were thoroughly planed using hand instruments and ultrasonic scalers.
