ABSTRACT
AIM:
To compare the efficacy of non-surgical re-instrumentation (NSR) and papillary preservation flap (PPF) surgery at single-rooted teeth with residual pockets. MATERIALS ANDMETHODS:
Patients with at least a residual pocket depth (PD ≥ 5 mm) after Steps I and II were enrolled and randomly assigned to receive NSR or PPF surgery. The primary outcome was PD reduction, and secondary outcomes were clinical attachment level (CAL) change and patient-reported outcome measures (PROMs). Outcome variables were measured at baseline, 3 and 6 months. The examiner was blinded. Statistical analysis, one site for each patient, included descriptive statistics and analysis of covariance.RESULTS:
Forty-six participants were enrolled, and one patient dropped out in the PPF group. After 6 months, both treatments resulted in significant PD reduction (1.3 ± 1.2 mm, p = .009 NSR; 2.0 ± 0.7 mm, p < .001 PPF) and CAL gain (1.0 ± 2.4 mm, p = .031 NSR; 1.4 ± 0.8 mm, p < .001 PPF). PD reduction between groups was not statistically significant (diff 0.6 mm; 95% confidence interval [CI] [-0.3 to 1.5]; p = .167). Pocket closure was 61% NSR versus 86% PPF (p = .091). Smoking was associated with less PD reduction of almost 1 mm in both treatments. Treatment time was longer for PPF surgery, but PROMs and post-operative pain were similar between groups.CONCLUSIONS:
Both NSR and PPF reduced PD without significant difference between treatments at 6 months. PPF surgery may offer faster PD reduction, but smoking habits reduce treatment efficacy.
