OBJECTIVES

To compare the healing of suprabony defects following treatment with either open flap debridement (OFD) and application of an enamel matrix derivative (EMD) with OFD alone.

METHODS

Eighty patients with suprabony periodontal defects were randomly assigned to treatment with OFD + EMD (test) or OFD alone (control). The primary outcome variable was the difference in clinical attachment level (CAL) gain. At baseline and after 12 months, full-mouth plaque scores (FMPS), full-mouth bleeding scores (FMBS), probing depths (PD), gingival recessions (GR), and CAL were recorded.

RESULTS

Sixty-five patients were available for the 12-month follow-up examination. At 12 months, the mean FMPS was 21.9 ± 3.0% in the OFD + EMD and 21.1 ± 2.4% in the OFD group, respectively (p = 0.30), while mean FMBS measured 20.4 ± 3.4% in the OFD + EMD group and 19.9 ± 2.9% in the OFD group (p = 0.48). Mean CAL gain at sites treated with OFD + EMD was statistically significantly different (p = 0.0001) compared with sites treated with OFD alone (3.4 ± 0.6 mm vs 1.8 ± 0.6 mm). A statistically significant difference (p = 0.0001) was found between mean PD change in the OFD + EMD (3.9 ± 0.6 mm) and OFD alone (3.2 ± 0.6 mm) treated groups and also in terms of mean GR change between treatment with OFD + EMD (0.5 ± 0.7 mm) and OFD alone (1.4 ± 1.0 mm) (p = 0.001).

CONCLUSION

Within their limits, the present results indicate that in suprabony periodontal defects, the application of EMD in conjunction with OFD may additionally improve the clinical outcomes compared with OFD alone.

CLINICAL RELEVANCE

In periodontal suprabony defects, the application of EMD in conjunction with OFD may additionally enhance the clinical outcomes in terms of CAL gain and PD reduction.
