Resumen
Background: The goal of this study was to evaluate the effectiveness of a composite bone graft (demineralized freeze-dried bone allograft, calcium sulfate, tetracycline, and porous hydroxyapatite) and calcium sulfate barrier to treat non-furcation osseous defects.
Methods: One hundred patients were treated with the technique. The preoperative measurements were compared to the postoperative measurements (mean 5.2 months) to determine whether the technique had a statistically significant effect. Various factors were evaluated to determine whether they could be related to improved or diminished results.
Results: The surgical procedure produced a statistically significant change in the clinical measurements. The mean recession increased from 0.8 to 1.8 mm; the mean probing depth decreased from 8.5 to 3.8 mm; and the attachment level improved from 9.3 to 5.5 mm. Non-smokers, defects in the mandibular arch, defects with deeper probing depths, or defects with greater attachment loss had statistically significant changes in one or more of the clinical parameters evaluated.
Conclusion: The technique examined in this study (composite bone graft + calcium sulfate barrier) was an effective method to improve the clinical measurements. J Periodontol 2004;75:685-692.
