Radiograph showed periodontal ligament widening and radiolucency in the furcation area along with a deep infrabony defect on the mesiobuccal root extending to root apex of tooth 36 [Figure 1].
During surgery (a) presence of one-wall defect in relation to mesial root of left mandibular first molar tooth (36); (b and c) vertical defect and furcation defect filled with demineralized freeze-dried bone allograft and platelet-rich fibrin membrane

Demineralized freeze-dried bone allograft (DFDBA) was placed along with platelet-rich fibrin (PRF) membrane in one wall defect present on mesiobuccal root and lingual furcation defect [Figure 2].

Clinical attachment loss of 4-mm mesially and on mesiobuccal aspect was present at 3-month postsurgically, which reduced to 3 mm at 6 months and remained stable at 2-year follow-up visit; and follow-up radiographs also showed good amount of bone fill in tooth 36 [Figures 4 and 5].
