Clinical Trial Summary

Generalized aggressive periodontitis (GAP) is an inflammatory disease that causes the severe and rapid destruction of periodontal tissue. A relatively constant microbiological pattern, an altered inflammatory condition and familial aggregation of cases were described as important characteristics of this disease. In this vein, studies evaluating children of GAP patients were made and identified early microbiological and inflammatory alterations in this population, suggesting that these factors could favor the disease development. Thus, the aim of this project is to evaluate if the use of toothpaste with Triclosan could have a beneficial effect in control the microbiota and the inflammatory condition in children from parents with GAP, comparing them to children of periodontally healthy parents. 20 children (6-12 years old) from GAP parents and 20 children (6-12 years old) from periodontally healthy parents will be selected and will participate in a cross-over placebo study. All children will be included in a 15-day period of control of plaque to standardize the hygiene technique using only the placebo toothpaste. After this period, the children will be divided randomly into 4 groups: G1: Triclosan/health children; G2: Placebo/health children; G3: Triclosan/GAP children; G4: Placebo/GAP children and they will use the specific paste described for each group for 45 days. After this period, all children will repeat the 15 days interval, using only the placebo toothpaste, to remove the Triclosan effect and to standardize the oral hygiene again. Posteriorly, the crossing of groups will be done and children will be reallocated to change the used toothpaste. Thus, children that were in G1 will be reallocated in G2, children of G2 will be reallocated in G1, children of G3 will be in G4 and children of G4 will be in G3, staying in this new group for more 45 days. The evaluated periods will be baseline, 15 days, 30 days and 45 days while children stay in G1, G2, G3 or G4. In these periods children will be clinically evaluated for the periodontal parameter and sample collection of crevicular gingival fluid (GCF) and subgingival biofilm from incisors and molars will be done. Luminex/MAGpix technology will be used to detect IL-1β, IL-4, IL-6, IL-8, IL-10, IL-17, TNF-α, INF-γ in the GCF. The subgingival biofilm will be used to evaluate the Porphyromonas gingivalis, Tannerella forsythia, Aggregatibacter actinomycetemcomitans levels by real-time PCR.


Description:

The data from each group will be compared by Student's t-test, Mann-Whitney test and chi-square test and a correlation between the inflammatory markers level and the subgingival bacterial concentration will be evaluated by Spearman`s correlation and regression analysis. The significance level for all analysis will be 5%.
