The effect of one session of supragingival plaque control on clinical and biochemical parameters of chronic periodontitis

Abstract

Supragingival plaque control is a requisite for the success of any periodontal procedure. However, little is know about the effect of this procedure alone on periodontitis. The aim of this study was to determine the effect of supragingival plaque control on clinical and biochemical parameters of chronic periodontitis. Twenty-five subjects exhibiting at least 4 pockets > 5mm, non-smokers and with no relevant systemic diseases, were selected for the study. The clinical and biochemical assessments were done before and 21 days after removal of plaque retentive factors, extraction of affected teeth and instruction in oral hygiene. The statistical analysis was done with the Student paired t-test (p<0,05) and demonstrated a reduction on the percentage of sites with bleeding on probing from 42.72 ± 15.83 to 35.87 ± 13.30 (p=0.002). Reduction in probing depth was detected on anterior teeth (initial/final mean: 2.88 mm/2.78 mm; p=0.01) and interproximal sites (initial/final mean: 3.80 mm/3.65 mm; p=0.001). There was an increase from 66.81% to 68.65% in the number of sites with probing depth of 1 to 3mm and a decrease from 26.21% to 24.17% in those with probing depth of 4 to 6mm. The BAPNA results showed a decrease from 51.44 ± 20.78 to 38.64 ± 12.34 (p=0.04). This study demonstrated that supragingival plaque control provides a reduction in gingival inflammation and alterations in the subgingival microflora detected by the BAPNA test.

Impact of supragingival therapy on subgingival microbial profile in smokers versus non-smokers with severe chronic periodontitis

“…It is, therefore, important to note that there is substantial evidence for the clinical improvement in smokers after treatment, indicating that smoking, as a risk factor, will compromise rather than prevent tissue healing. In non-smokers, ST results in a reduction in gingival bleeding, probing depth, and a gain in attachment level (7, 9, 13, 14, 39, 40). In smokers, however, there was a lack of information on the impact of ST on the periodontal tissues at untreated sites.…”

“…subgingival scaling and root planing, is effective in the achievement of this goal. Supragingival biofilm control has been shown to play a critical role in the success of periodontal therapy due to its impact on the subgingival biofilm and its inhibition of re-colonization (7–9). However, conflicting results regarding the impact of supragingival biofilm control on the composition of established subgingival biofilm in untreated periodontal sites are found in the literature (10–14).…”

The Biofilm Community: Rebels with a Cause

“…Understanding these bacterial biofilm communities will provide knowledge to design new treatments for chronic infectious diseases. It was also noted that supragingival biofilm regulation plays a critical role in therapy due to its impact on the inhibition of re-colonization in the subgingival biofilm [44,45,46]. It was also noted that there has been conflicting results regarding the impact on the control of supragingival biofilm on the composition of subgingival biofilm in the untreated periodontal sites [47,48,49].…”
