Abstract

The ultimate goal of periodontal treatment is to regenerate the lost periodontal apparatus. Many studies were performed in developing an ideal bone substitute. Anorganic bovine-derived xenograft is one of the bone substitues, which were studied and have been shown successful for decades.
The aim of this study is to evaluate the effect anorganic bovine-derived xenograft.
Total of 20 patients, with 10 patients receiving only modified widman flap, and the other 10 receiving anorganic bovine-derived xenograft and flap surgery, were included in the study. Clinical parameters were recorded before surgery and after 6 months.
The results are as follows:

  1. The test group treated with anorganic bovine-derived xenograft showed reduction in periodontal pocket depth and clinical attachment level with statistically significance(p<0.001) after 6 months. The control group treated with only modified Widman flap showed reduction only in periodontal pocket depth with statistically significance(p<0.001) after 6 months.

  2. Although periodontal probing depth change during 6 months did not show any significant differences between the test group and the control group, clinical attachment level gain and recession change showed significant differences between the two groups(p<0.05).

On the basis of these results, anorganic bovine-derived xenograft improves probing depth and clinical attachment level in periodontal intrabony defects. Anorganic bovine-derived xenograft could be a predictable bone substitute in clinical use.
