Abstract
Purpose
The present study aimed to evaluate the clinical and radiographic effects of
autologous platelet concentrate (APC) on the healing of intra-bony defects filled
with β-tricalcium phosphate (β-TCP) and covered with collagen membranes.
Subjects and methods
This study included 30 defects of 14 systemically healthy subjects. All of them had,
at least, two deep intra-bony, inter-proximal periodontal defects. Minimum probing
pocket depth (PPD) was 6 mm. Clinical and imaging examination was performed
both at baseline and at 3, 6, and 9 months after surgery.
Results
Both the test and control group revealed a significant reduction in all variables
when compared with the base line. Mean reduction of the PPD in two groups at
each follow-up time point showed no significant difference. Means of the clinical
attachment gain of the same groups were significantly different (p<0.05). Mean
gingival recession at 3 month was not significant. However, the means of gingival
recession coverage of two groups were significantly different at 6 and 9 months
(p<0.05 for both).
Conclusion
Sites treated with APC are more likely to demonstrate more clinical attachment gain
and recession coverage at the end of 9 month compared to those without APC.
