The purpose of this study was to evaluate the efficiency of combined use of autogenous tooth bone graft (Auto-BTⓇ) with absorbable membrane (OsseoguardⓇ) for surgically created Class Ⅱ furcation defects histologically and histomorphometrically.
Five dogs were used in this study. The Class Ⅱ furcation defects (5 x 4 x 3 mm) were formed at lower third and fourth premolar, respectively. The control group defects were covered with OsseoguardⓇ only while the experimental group defects were treated with Auto-BTⓇ and then covered with OsseoguardⓇ. The healing patterns were observed at 4 weeks and 8 weeks after treatment.
Mesio-distal sections stained with hematoxylin and eosin were analyzed histoloically and histomorphometrically, resepectively. Statistical analyses were performed using Mann-Whitney test and Wilcoxon ranked test.
The regeneration of new bone, cementum, and periodontal ligament at the furcation defects was more favorable in experimental groups which additional Auto-BTⓇ graft were applied compared to membrane only applied control group but there was no statistical significant differences in histomorphometric measurements.
In conclusion, this study showed that additional Auto-BTⓇ graft for Class II furcation defects with covering of OsseoguardⓇ membrane might partially improve the healing efficiency.
