Biphasic Calcium Phosphate Versus Demineralized Freeze-Dried Bone Allograft in the Treatment of Periodontal Disease: A Clinical and Radiographical Evaluation

Abstract

Aim The study aimed to clinically and radiographically evaluate the effect of biphasic calcium phosphate (BCP) versus demineralized freeze-dried bone allograft (DFDBA) in treating periodontal disease. Method The study consisted of 44 patients. The sites were randomly assigned to receive one of two treatment modalities (BCP at site 1 and demineralized freeze-dried bone at site 2) by a computerized method. All the clinical data were measured with the help of a University of North Carolina-15 (UNC-15) probe at the baseline, three months, and six months postoperatively. Radiovisiographs were taken using a Rinn XCP® (Dentsply/Rinn Corp, Elgin, IL) system and an oral grid using the paralleling technique. A manual calculation of the defect area was undertaken at the end of six months and was compared with the other groups. Result The linear bone growth recorded for site 1 at the end of six months was 3.8 ± 1.14 mm, and site 2 was 4.6 ± 1.07 mm. The intergroup comparison showed more remarkable linear bone growth in site 2, which was statistically insignificant, with a mean difference of 0.8 ± 1.23 mm and a p -value of 0.07. Conclusion Improvements were observed on all the documented parameters. However, the sites treated with DFDBA showed better periodontal regeneration.

Efficacy of Calcium Phosphate Composite Bone Graft in Treatment of Periodontal Intrabony Defects: Clinico-Radiographic Study

“…The periodontal regeneration is defined as the development of the collagen fiber and bone. It also involve formation of the three layers of the tissue [1][2][3] . For the filing of the IBD and regeneration of the bone in the periodontal therapy, different bone graft are used.…”
