AIM: To examine the adjunctive effect of a Lactobacillus reuteri probiotic (ATCC PTA 5289 & DSM 17938) on the re-instrumentation of residual pockets. MATERIALS AND METHODS: This randomized, double-blind, placebo-controlled study included 39 previously non-surgically treated periodontitis patients. A re-instrumentation was carried out, and probiotic and/or placebo drops were applied according to the study protocoll. Patients afterwards received lozenges to use 2×/day for 12 weeks. Probing pocket depth (PPD), recession, bleeding on probing and plaque levels were analysed, next to the microbiological impact. RESULTS: No effects of the probiotic drops could be found. However, after 24 weeks, the overall PPD in the probiotic lozenges group (2.64 ± 0.33 mm) was significantly lower compared to the control lozenges (2.92 ± 0.42 mm). This difference was even more pronounced in moderate (4-6 mm) and deep (≥7 mm) pockets. In the probiotic lozenges group, there were also significantly more pockets converting from ≥4 mm at baseline to ≤3 mm at 24 weeks (67 ± 18% versus 54 ± 17%) and less sites in need for surgery (4 ± 4% versus 8 ± 6%). However, the probiotic products did not influence the microbiological counts of the periodontopathogens. CONCLUSION: The adjunctive consumption of L. reuteri lozenges after re-instrumentation improved the PPD reduction, without an impact on pocket colonization with periodontopathogens. ispartof: JOURNAL OF CLINICAL PERIODONTOLOGY vol:47 issue:1 pages:43-53 ispartof: location:United States status: published

Methods: In a prospective PMT program, 75 regular complier (RC) and 89 erratic complier (EC) patients were selected. A periodontal examination and PRA were performed after active periodontal therapy and after 3 years of PMT. Risk profiles (low, moderate, or high) of participants were evaluated, and the recurrence of periodontitis and tooth loss were analyzed using univariate and multivariate analyses. Results: RCs showed less recurrence of periodontitis and tooth loss than ECs (P

Prospective study of complier individuals under periodontal maintenance therapy: analysis of clinical periodontal parameters, risk predictors and the progression of periodontitis. J Clin Periodontol 2009; 36: 58-67. doi: 10.1111/j.1600-051X.2008.01342.x. This prospective study aimed to evaluate the progression of periodontitis and the influence of risk variables among individuals attending a programme of periodontal maintenance treatment in an academic environment. A total of 150 individuals diagnosed with chronic moderate-advanced periodontitis, and who had finished active periodontal treatment, were incorporated into the periodontal maintenance therapy. Social, demographic and biological variables of interest from subjects were collected at quarterly recalls, over a 12-month period. The effect of variables of interest and confounding on the periodontal status and progression of periodontitis was tested by univariate and multivariate logistic analysis. A total of 130 subjects (86.7%) showed stable periodontal status, whereas 20 subjects (13.3%) presented periodontitis progression. Twenty-eight subjects (18.66%) presented tooth loss that resulted in a total of 47 lost teeth (1.38%). Diabetes was not found to be associated with periodontitis progression (p=0.67). Smoking was significantly associated with a greater progression of periodontitis (OR=2.7, 95% CI 1.01-7.22). Periodontal maintenance programmes in academic environment can stabilize the periodontal condition obtained after active periodontal therapy as well as control the action of risk variables for the progression of periodontitis.
