Effect of Autogenous Cortical BoneParticulate in Conjunction With EnamelMatrix Derivative in the Treatment ofPeriodontal Intraosseous DefectsLuigi Guida,* Marco Annunziata,* Salvatore Belardo,* Roberto Farina,† Alessandro Scabbia,†and Leonardo Trombelli† Background: The aim of the present study was to assess the additional clinical benefit of autogenous cortical bone particu-late (ACBP) when added to enamel matrix derivative (EMD),compared to EMD alone, in the treatment of deep periodontalintraosseous defects.
Methods: A total of 28 intraosseous lesions in 27 patients with advanced periodontitis were included in this controlledclinical trial and randomly assigned to the EMD group (14 de- fects) or to the EMD + ACBP group (14 defects). Immediately before surgery (baseline) and after 6 and 12 months, probing depth (PD), clinical attachment level (CAL), and gingival re- cession (REC) were recorded. Radiographic depth of the de- fect (DEPTH) was also measured at baseline and 12 months Results: At 6 and 12 months, PD and CAL significantly im- proved from baseline in both groups (P <0.000). No significant differences in terms of CAL gain and PD reduction were de- tected between groups. However, defect distribution according to CAL gain was significantly different between groups (P <0.05). DEPTH significantly decreased from baseline to 12 months in both groups (P <0.000); between-group differences were not significant. At 12 months, a significantly greater REC increase in the EMD group (1.1 – 0.7 mm) compared to the EMD + ACBP group (0.3 – 0.8 mm) was observed (P <0.05).
Conclusions: Both EMD and EMD + ACBP treatments led tial, which may potentially affect its re- to a significant improvement in clinical and radiographic pa- rameters at follow-up with respect to presurgery condition. The combined approach resulted in reduced post-surgery recession and increased proportion of defects with substantial CAL gain (‡6 mm). J Periodontol 2007;78:231-238.

For instance, the use of a biomaterial with a gel-like consistency, such as EMD, in a non–self-supporting intraosseous defectmay result in a limited clinical outcome due to the col- lapse of the flap into the bone defect during the early healing phase, particularly in deep, non-containingintraosseous defects.14 These observations seem to * Significant difference between groups (P <0.05).
