Compliance with supportive periodontal therapy and its relation to the bleeding index

THIS IS A RETROSPECTIVE STUDY of 418 patients who received active periodontal treatment between the years of 1984 and 1990. The patients were instructed to return for supportive periodontal treatment (SPT) at 3 to 6-month intervals. The objective of this study was to evaluate patient compliance with periodic recall visits, and to study the relationship of bleeding upon probing in those who returned regularly. The patients were divided into 3 groups: patients who returned periodically for supportive treatment, patients who interrupted the proposed maintenance treatment, and patients who never returned after active periodontal treatment. Analysis was made for each group to correlate the degree of compliance with gender, disease classification, and type of treatment received. To analyze bleeding upon probing, 2 groups of patients were selected: a test group with 39 patients who had attended at least 10 recall visits and participated in the study for more than 40 months, and a control group of 21 patients who interrupted the SPT for at least 12 months. The results showed that 26% of the treated patients returned for SPT and, of those, 40% returned irregularly. There was a statistical significant difference in compliance in relation to disease classification and the type of treatment received, but no correlation was found between compliance and gender. There was a statistically significant difference in compliance between the test group and the control group in relation to the variation of the bleeding index.

The effect of non-surgical periodontal therapy on peroxidase activity in diabetic patients: a case-control pilot study

Objective: To evaluate the effect of periodontal therapy on clinical parameters as well as on total salivary peroxidase (TSP) activity and myeloperoxidase (MPO) activity in the gingival crevicular fluid (GCF) of patients with type 2 diabetes mellitus (DM2) and of systemically healthy individuals.Material and Methods: Twenty DM2 subjects with inadequate metabolic control (test group) and 20 systemically healthy individuals (control group), both groups with chronic periodontitis, were enrolled. Periodontal clinical parameters, namely periodontal probing depth (PD), clinical attachment level (CAL), visible plaque index (VPI), bleeding on probing (BOP), gingival bleeding index (GBI) and presence of suppuration (SUP), as well as TSP activity and GCF MPO activity, were assessed before and 3 months after non-surgical periodontal therapy.Results: At baseline and 3 months post-treatment, the test group presented a higher percentage of sites with VPI and BOP (p < 0.01). MPO activity in the GCF presented lower values (p < 0.05) for the test group at both baseline and the post-treatment period. The periodontal treatment resulted in a significant improvement of most clinical and enzymatic parameters for both groups (p < 0.05).Conclusions: In both groups, the periodontal therapy was effective in improving most clinical parameters and in reducing salivary and GCF enzymatic activity. The diabetic individuals presented lower MPO activity in the GCF.

Effect of Supragingival plaque control in smokers and never-smokers: 6-month evaluation of patients with periodontitis

Background: the effect of supragingival plaque control on clinical signs of periodontitis is controversial, particularly when smoking habits are considered. This study evaluated the clinical effects of supragingival plaque control on clinical signs of periodontitis in smokers and never-smokers.Methods: the following data were collected for 25 never-smokers and 25 smokers at baseline and 30, 90, and 180 days: visible plaque index (VPI), gingival bleeding index (GBI), bleeding on probing (BOP), periodontal probing depth (PD), and clinical attachment loss (CAL). After baseline examinations, supragingival scaling was performed. Oral hygiene practices were reinforced and reevaluated weekly during the experimental period. Linear models adjusted for clustering of observations within individuals were used for statistical analysis.Results: Reductions in VPI were significant for both groups, with no intergroup differences. GBI at baseline was similar between groups, and at 30, 90, and 180 days, smokers had a lower GBI than never-smokers. Significant reductions were observed in PD for shallow (1 to 3 mm), moderate (4 to 5 mm), and deep sites (>= 6 mm) in both groups. CAL was significantly greater in smokers throughout the study, but gains in attachment were similar for both groups (0.71 to 1.00 mm). BOP reductions were similar in both groups.Conclusions: Supragingival plaque control resulted in significant changes in clinical parameters associated with gingivitis and periodontitis. Smoking did not affect results, regardless of initial PD.

Periodontal status in smokers and never-smokers: Clinical findings and real-time polymerase chain reaction quantification of putative periodontal pathogens

Background: Smoking is a well-known risk factor for destructive periodontal disease, but its relationship with periodontal status and subgingival microbiota remains unclear. Inherent limitations of microbiological methods previously used may partly explain these mixed results, and real-time polymerase chain reaction (PCR) has been presented as a valid alternative. The aim of the present study was to investigate the clinical condition and microbiological profile of patients with chronic periodontitis as related to the habit of smoking.Methods: Fifty patients (33 to 59 years old), 25 smokers and 25 never-smokers, constituted the sample. The visible plaque index (VPI), gingival bleeding index (GBI), bleeding on probing (BOP), periodontal probing depth (PD), clinical attachment loss (CAL), and gingival crevicular fluid (GCF) volume were recorded. Real-time PCR quantified Porphyromonas gingivalis, Micromonas micros, Dialister pneumosintes, Actinobacillus actinomycetemcomitans and total bacteria in subgingival samples.Results: Smokers and never-smokers showed similar values for VPI, GBI, and BOP. Smokers had deeper PD in buccal/lingual sites and higher CAL independently of the tooth surface. The GCF volume was smaller in smokers, independent of the PD. Similar amounts of total bacteria and P. gingivalis were observed for both groups. Significantly higher numbers of D. pneumosintes and M. micros were present in smokers and associated with moderate and deep pockets. When heavy smokers were considered, higher counts of total bacteria, M. micros, and D. pneumosintes were observed.Conclusions: Smoking seems to have a detrimental impact on the periodontal status and microbiological profile of patients with periodontitis. Compared to never-smokers, smokers had deeper pockets, greater periodontal destruction, and higher counts of some putative periodontal pathogens.

Evaluation of clinical periodontal conditions in smokers and non-smokers

Given that tobacco smoking habit is a risk factor for periodontal diseases, the aim of this study was to compare clinical periodontal aspects between smokers and non-smokers. The clinical status were assessed in 55 patients, 29 smokers and 26 non-smokers, aged 30 to 50 years, with mean age of 40. The clinical parameters used were: probing depth (PD), plaque index (PI), gingival index (GI), clinical attachment level (CAL), gingival recession (GR) and gingival bleeding index (GBI) for arches (upper and lower ) and teeth (anterior and posterior). Tooth loss was also evaluated in both groups. Multiple regression analysis showed: tendency of greater probing depth and clinical attachment level means for smokers; greater amount of plaque in smokers in all regions; greater gingival index means for non-smokers with clinical significance (p<0.05) in all regions. Although, without statistical significance, the analysis showed greater gingival bleeding index means almost always for nonsmokers; similar gingival recession means in both groups and tendency of upper tooth loss in smokers and lower tooth loss in non-smokers. The findings of this study showed that clinical periodontal parameters may be different in smokers when compared to non-smokers and that masking of some periodontal signs can be a result of nicotine's vasoconstrictor effect.
