Long Term Healing of Furcation Defects Using PRG or GTR
Objectives: To evaluate clinically the long-term results following treatment of mandibular Grade II. furcation defects with Platelet-Rich Gel (PRG) to a collagen membrane (GTR).
Methods: Sixteen patients suffering from advanced chronic periodontitis, and each of whom displayed one mandibular Grade II. furcation defect were randomly treated with either PRG (test) or GTR (control). Clinical parameters were evaluated at baseline, at 1 year and 3 years after treatment. The primary outcome variable was the horizontal ’bone sounding’ (BSH).
Results: In the test group mean BSH changed from 5.63 ± 1.30 mm to 5.13 ± 1.36 mm after one year, and to 4.88 ± 1.46 mm three years postoperative. In the control group mean BSH values changed from 6.25 ± 1.04 mm to 5.25 ± 1.04 mm one year, and to 4.63 ± 2.67 mm three years after surgery. Compared to baseline, the improvements of mean BSH values were statistically not significant. No statistically significant differences in any of the investigated parameters were observed between the two groups at 1 and 3 years.
Conclusions: Both treatments resulted in nonsignificant PPD reductions and CAL gains measured at furcation entrance after three years. No statistically significant differences were registered between groups regarding the mean BSH values after three years observation period.
