Effectiveness of nonsurgical re‐instrumentation: Tooth‐related factors
BackgroundTo investigate tooth‐related factors that influence pocket closure (PC) and the reduction of pocket probing depths (PPD) after nonsurgical re‐instrumentation (NSRI) as part of step 3 therapy.MethodsA total of 480 patients (10,807 teeth) presenting with residual pockets 6.33 ± 3.79 months after steps 1 and 2 of periodontal therapy were included and retrospectively analyzed before and 5.93 ± 4.31 months after NSRI. Reduction of PPD and PC rates following NSRI were associated with tooth‐related factors, namely tooth type, arch, number of roots, furcation involvement (FI), pulp vitality, mobility, type of restoration, presence of plaque, and bleeding on probing (BOP), using mixed‐effects regression models.ResultsNSRI reduced periodontal pockets persisting after initial cause‐related therapy by (mean ± SD) 1.32 ± 1.79 mm in PPD, and PC rate was 40%.

Both PPD reduction and PC rates of deep residual pockets were significantly influenced by tooth type, arch, number of roots, and presence of BOP.ConclusionTooth type, arch, number of roots, and presence of BOP at re‐evaluation (before NSRI) had a significant and clinically relevant influence on NSRI as part of step 3 therapy.
