Periodontal infection control: current clinical concepts

ENDODONTIC TOPICS, Issue 1 2006
JAN L. WENNSTRÖM
The main objective of the treatment of patients with periodontitis is to establish adequate infection control in the dentogingival area. Pocket/root instrumentation (scaling and root planing), combined with effective self-performed supragingival plaque control measures, constitute the basic treatment modalities, but also locally applied antiseptics and antibiotics may be utilized. The purpose of this article is to give an overview of current clinical concepts on periodontal infection control. [source]


Clinical attachment loss produced by curettes and ultrasonic scalers

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 7 2005
Renato Vasconcelos Alves
Abstract Objectives: The aim of this study was to clinically detect the immediate effect of root instrumentation with curettes and ultrasonic scalers on clinical attachment level. Material and Methods: Twelve subjects with moderate chronic periodontitis, presenting probing depths of 3.5,6.5 mm on anterior teeth, upper and/or lower, were selected. Teeth were randomly assigned to one of the following groups: US group , scaled with an ultrasonic scaler; and CC group , scaled and planed with 5,6 Gracey curettes. The selected teeth were probed with a computerized electronic probe, guided by an occlusal stent and subjected to scaling and root planing. Immediately following instrumentation, teeth were probed again. The difference between relative attachment level (RAL) immediately before and after instrumentation was considered trauma from instrumentation. Results: Intra-group analysis revealed statistically significant differences between RAL immediately before and after instrumentation in both groups (0.77±0.51 for US group; and 0.73±0.41 for CC group, p<0.0001). However, inter-group analysis did not show statistically significant difference in trauma from instrumentation caused by the two different instruments (p=0.816). Conclusions: Within the limits of this study, it was concluded that root instrumentation causes a mean immediate attachment loss of 0.75 mm, and that instrumentation with either curettes or ultrasonic scalers do not seem to reduce significantly the trauma from of instrumentation produced.

Clinical outcomes following treatment of human intrabony defects with GTR/bone replacement material or access flap alone

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 9 2004
A multicenter randomized controlled clinical trial
Abstract Aim: This prospective multicenter randomized controlled clinical trial was designed to compare the clinical outcomes of papilla preservation flap surgery with or without the application of a guided tissue regeneration (GTR)/bone replacement material. Materials and Methods: One hundred and twenty-four patients with advanced chronic periodontitis were recruited in 10 centers in seven countries. All patients had at least one intrabony defect of 3 mm. The surgical procedures included access for root instrumentation using either the simplified or the modified papilla preservation flap in order to obtain optimal tissue adaptation and primary closure. After debridement, the regenerative material was applied in the test subjects, and omitted in the controls. At baseline and 1 year following the interventions, clinical attachment levels (CALs), probing pocket depths (PPDs), recession, full-mouth plaque scores and full-mouth bleeding scores (FMBS) were assessed. Results: One year after treatment, the test defects gained 3.3±1.7 mm of CAL, while the control defects yielded a significantly lower CAL gain of 2.5±1.5 mm. Pocket reduction was also significantly higher in the test group (3.7±1.8 mm) when compared with the controls (3.2±1.5 mm). A multivariate analysis indicated that the treatment, the clinical centers, baseline PPD and baseline FMBS significantly influenced CAL gains. Odds ratios (ORs) of achieving above-median CAL gains were significantly improved by the test procedure (OR=2.6, 95% CI 1.2,5.4) and by starting with deeper PPD (OR=1.7, 1.3,2.2) but were decreased by receiving treatment at the worst-performing clinical center (OR=0.9, 0.76,0.99). Conclusions: The results of this trial indicated that regenerative periodontal surgery with a GTR/bone replacement material offers an additional benefit in terms of CAL gains, PPD reductions and predictability of outcomes with respect to papilla preservation flaps alone.

Attachment loss after scaling and root planing with different instruments

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 1 2004
A clinical study
Abstract Objectives: The aim of this study was to evaluate clinically the immediate effect of trauma from instrumentation after scaling and root planing with different instruments. Material and Methods: Ten subjects with moderate chronic periodontitis, presenting probing depths ranging from 3.5 to 6.5 mm on anterior teeth, upper and/or lower, were selected. Teeth were randomly assigned to one of the following groups: MC group , scaled and planed with Gracey mini-curettes (MiniFiveTM); CC group , scaled and planed with Gracey conventional curettes. The selected teeth were probed with a computerized electronic probe, guided by an occlusal stent, and then subjected to scaling and root planing. Immediately following instrumentation, teeth were probed again. The difference between relative attachment level (RAL) immediately before and after instrumentation was considered as trauma from instrumentation. Results: Intra-group analysis revealed statistically significant differences between RAL immediately before and after instrumentation in both groups (0.68±0.32 for MC group; and 0.83±0.41 for CC group ,p<0.05). However, inter-group analysis did not show a statistically significant difference in trauma from instrumentation caused by the different instruments. Conclusions: Within the limits of this study, it was concluded that root instrumentation causes an average trauma from instrumentation of 0.76 mm with no differences between the tested instruments.
