OBJECTIVES

To assess the association between the baseline radiographic defect angle and the long-term clinical outcomes following periodontal regenerative therapy with Enamel Matrix Derivative (EMD).

METHOD AND MATERIALS

Baseline peri-apical radiographs obtained from a cohort of patients treated with periodontal regenerative therapy were digitized and the radiographic angle width between the root surface and the bony wall of the adjacent intraosseous defect was calculated and reported in degrees (°). Changes in pocket probing depth (PD) and clinical attachment level (CAL) were assessed and reported in mm. Clinical outcomes were evaluated at baseline (T0), 6 months following therapy (T1) and at the latest follow-up (T2).

RESULTS

Thirty-eight defects in 26 patients enrolled in supportive periodontal care for a mean period of 10.4 years (range: 8.0 - 15.5 years) were available for analysis. The mean PD change between T0 and T2 was 2.33 ± 1.66 mm at teeth with a defect angle width < 20° and 0.86 ± 1.66 mm at teeth with a defect angle width > 30° (p = 0.021). When the baseline radiographic angle width was < 20° the probability of obtaining a CAL gain > 3 mm was 1.5x higher (95% CI: 0.19 - 13.8) at T1 and 2.5x higher (95% CI: 0.40 - 15.6) at T2 compared with defects with a radiographic angle width > 30°.

CONCLUSION

Within their limitations, these results indicate that pre-therapeutic measurement of the radiographic defect angle width might provide relevant information on the short/long-term clinical outcomes following regenerative periodontal therapy with EMD.
