Aims:
The purpose of this study was to evaluate the regenerative response of parietal bone defects in rats to bioactive ceramic and TGF-beta 1.
Materials And Methods:
Sixty mature adult rats with initial weights of 300 g to 324 g were used. The diameter of each defect was 3 mm. The animals were divided into four study groups consisting of 15 rats per group. Groups 1 and 3 (control groups) received 30 μg bioceramic per surgical defect site. Groups 2 and 4 (experimental groups) received 30 μg bioceramic combined with 10 μL of reconstituted TGF-beta 1 (200 ng). Animals of Groups 1 and 3 were euthanized at 18 days; Group 2 and 4 animals were terminated at 49 days after surgery. Each of the outcomes was analyzed via two-way analysis of variance model (ANOVA).
Results:
Histologic reactions to the implants were similar with no significant difference between bioceramic and bioceramic + TGF-beta 1 specimens. In the 18-day specimens, the percentage of ceramic was marginally higher than the 49-day specimens. No significant difference was noted in the percentage of bone in 18-day and 49-day specimens.
Conclusions:
Based on the findings of this study, it was concluded that TGF-beta 1 promoted no significant increase in new bone when compared to bioactive ceramic alone.
