Background:The ultimate goal of periodontal therapy entails regeneration of the periodontal tissues lost as a consequence of periodontitis. Predictable correction of vertical osseous defects has however posed as a constant therapeutic challenge. The aim of our present study is to evaluate the relative efficacy of demineralized freeze-dried bone allograft (DFDBA) vs anorganic bovine bone xenograft (ABBX) in the treatment of human infrabony periodontal defects.Materials and Methods:15 patients with 30 bilaterally symmetrical defect sites in either of the arches, in the age group of 25-50 years were selected as part of split-mouth study design. Defect-A (right side) was grafted with DFDBA while Defect-B (left side) was grafted with ABBX. Various clinical and radiographic parameters viz. probing depth(PD), clinical attachment level(CAL) and linear bone fill were recorded preoperatively, 12- & 24-weeks postoperatively.Results:Both defect-A & defect-B sites exhibited a highly significant reduction in probing depth, and gain in clinical attachment level and linear bone fill at 12-weeks & at the end of 24-weeks. Comparative evaluation between the study groups revealed a statistically non-significant reduction in probing depth (P<0.1) and mean gain in linear bone fill (P<0.1). However, there was a statistically significant gain in clinical attachment level (P<0.05) in Defect-A (CD=0.356) as compared to Defect-B (CD=0.346).Conclusions:Within the limits of this study, both the materials viz. ABBX and DFDBA are beneficial for the treatment of periodontal infrabony defects. Both the materials were found to be equally effective in all respects except the gain in attachment level, which was found to be more with DFDBA. Long-term studies are suggested to evaluate further the relative efficacy of the two grafts.
Background:
The platelet-rich fibrin (PRF) has proven an immense role in angiogenesis and epithelization in a wound healing process. The present study aims to ascertain PRF's beneficial role in wound healing after depigmentation surgery.
Materials and Methods:
A total of 12 systemically healthy controls included were divided into two groups after scalpel depigmentation procedure. PRF was prepared according to Choukroun's standard protocol. Using split-mouth design after depigmentation, one group received PRF membrane, and in second group non-eugenol periodontal dressing was placed. The participants were evaluated for visual analog scale (VAS), healing index (HI) on 3
rd
and 5
th
day. Epithelization test using toluidine blue and histological examination employing punch biopsy was done on the 5
th
day.
Results:
On statistical scale, VAS, HI, epithelization test, and histological findings were statistically significant in the two study groups. PRF group proved better epithelization test and inflammatory cell infiltration was less in PRF group which confirmed superior wound healing in the group.
Conclusion:
PRF membrane postdepigmentation provided satisfactory patient comfort and enhanced the wound healing cascade.
