Abstract

The test group showed statistically significant differences in bone defect height, depth, and width compared to the control group.

Demineralized freeze-dried bone allograft combined with concentrated growth factor resulted in greater reductions in probing pocket depth.
The addition of concentrated growth factor was associated with increased clinical attachment level gains.
Radiographic evaluations indicated better outcomes in bone defect height, depth, and width with the test treatment.
The findings suggest that concentrated growth factor may enhance the effectiveness of demineralized freeze-dried bone allograft in treating periodontal intrabony defects.

BACKGROUND: The current study's aim was to evaluate and compare demineralized freeze-dried bone allograft (DFDBA) with and without concentrated growth factor (CGF) membrane in the treatment of periodontal intrabony defects on both a clinical and radiographic level.

METHODS: 30 stage III grade B periodontitis patients with bilateral intrabony defects were involved in the split mouth randomized controlled trial, and they received either DFDBA alone (control group) or DFDBA plus CGF membrane treatment (test group). At baseline and 6 and 12 months, the gingival index (GI), plaque index (PI), probing pocket depth (PPD), clinical attachment level (CAL), and gingival recession (GR) were assessed, whereas cone beam computed tomography was used to assess the bone defect height (BDH), vertical bone loss (VBL), bone defect depth (BDD), mesio-distal bone defect width (MDBDW), bucco-lingual bone defect width (BLBDW), and bone defect volume (CBCT) at baseline and 12 months.

RESULTS: The radiographic measures BDH, BDD, MDBDW, BLBDW, and BDV in the test group likewise showed a higher reduction in PPD and gain in CAL than the control group. The results of the intergroup comparison showed that the test group had statistically significant differences in BDH, BDD, and MDBDW.

CONCLUSION: The data show that the test group achieved better results, with greater reductions in PPD, gains in CAL, and decreases in BDH, BDD, MDBDW, BLBDW, and BDV.

CLINICAL RELEVANCE: The use of concentrated growth factor in conjunction with demineralized freeze-dried bone allograft may be suggested for the treatment of periodontal intrabony defects.
