Comparative evaluation of clinical efficacy of β-tri calcium phosphate (Septodont-RTR)™ alone and in combination with platelet rich plasma for treatment of intrabony defects in chronic periodontitis

J Indian Soc Periodontol. 2014 May;18(3):346-51. doi: 10.4103/0972-124X.134573.

Abstract

Aim: To assess the clinical outcome by comparing β-tri calcium phosphate (Septodont RTR)™ along with platelet rich plasma (PRP) and β-tri calcium phosphate (β-TCP) alone in intrabony defects, by clinical evaluation in a 6-month analysis.

Methodology: Ten patients participated in the study. Using a split-mouth design, interproximal bony defects were surgically treated with either platelet rich plasma (PRP) combined with β-tri calcium phosphate (β-TCP) or β-TCP alone. Plaque Index (PI), Gingival Index, Probing Pocket Depth (PPD), Clinical Attachment Level (CAL) were recorded 6 months after surgery.

Results: At 6 months after therapy, the PRP combined with β-TCP group showed mean PPD reduction of 2.50, CAL mean gain of 2.60 + 1.43. The β-TCP group showed mean PPD reduction of 2.80 mm, mean CAL gain of 2.60 mm. On intra-group comparison, there was greater PPD reduction and CAL gain at 6 months in both the groups. In intergroup comparison of PRP/β-TCP and β-TCP alone, there was no statistical significant difference observed. (P = 0.55, and 0.87 for PPD and CAL gain).

Conclusion: Both therapies resulted in significant PPD reduction, CAL gain. The present study shows that treatment of intrabony periodontal defects with combination of PRP and β-TCP does not have additional improvements when compared with β-TCP alone within 6 months follow-up.
