A patient diagnosed with palatal radicular groove and a localized periodontal disease was treated by procedures to control bacterial action and procedures to eliminate local predisposing risk factor. To treat the periodontal bone defect a sequelae of periodontal disease, a guided tissue regeneration technique was applied by using allograft and xenograft materials associated with a resorbable demineralized bovine cortical bone membrane. The objective of surgical regenerative procedure was to recover the periodontal tissues nearly as they were before periodontal disease destruction.1-5engBacteriaEtiologyGuided tissue regenerationPeriodontal diseaseArtigoAcesso restrito4185776888167996755582425605334432213606529928974475459130259433835073544536047856917302842593445007703439443544
