Abstract

Objectives: The present study aimed to evaluate the effect of ; 1- combined demineralized freez dried bone allograft( DFDBA)plus hyaluronic acid(HA) compared to DFDBA alone, and 2) combined DFDBA/HA compared to DFDBA /PRP in treatment of periodontal infrabony defects(PIDs).
Subjects and methods:45 infrabony defects in subjects with chronic periodontitis were randomly divided into 3 groups treated with, group 1: DFDBA/HA, group 2: DFDBA/PRP and group 3: DFDBA alone. Clinical and radiographic measurements were made at baseline and 12 months after surgery. ANOVA followed by Tukey’s post hoc test were used to analyze the data.
Results: A statistically significant improvement in clinical attachment level( Cal) and pocket depth ( PD) as well as radiographic bone fill were reported in group 1 and 2 compared to DFDBA alone( p ≤ 0.05), a non significant difference was reported between group 1 and group 2 regarding clinical and radiographic parameters(p > 0.05).
Conclusion : Results of the present investigation suggests that the combination of DFDBA/HA is more effective both clinically and radiographically than DFDBA alone in treatment of PIDs and that both HA and PRP combined with DFDBA are equally effective in treatment of these defects.
