Abstract

The present study hypothesized that some systemic conditions such as, diabetes and obesity, could affect negatively the response to gingival treatment. Aims: this interventional study will evaluate if diabetes, obesity or its association interfere in the host response to mechanical-chemical treatment of gingivitis. Also, to evaluate the relation between oral health and either quality of life or daily performance of systemically compromised subjects. Methods: 240 gingivitis subjects will be selected and divided in 4 groups: diabetes (n=60), obesity (n=60), diabetes+obesity (n=60) and control (systemically healthy, n=60), in addition to a negative control group (systemic and gingival health, n=60). All groups will receive professional prophylaxis (ultrasonic and/or rubber cup and prophylaxis paste, according to their gingival status) and oral hygiene instructions. Subsequently, subjects from each group will be randomly allocated in test (Listerine total care; n=30) or placebo (n=30). The parameters that will be measured at baseline and 90 days are: clinical - plaque índex, gingival índex and probing depth; microbiological: quantification (qPCR) of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tanerella forsythia, Treponema denticola, and Streptococcus oralis in gingival samples; imune: volume and composition of gingival crevicular fluid (ELISA detection of cytokines); salivary: flow and composition (total protein level); halitosis: organoleptic analysis and halitometry; questionnaires focusing on relation between oral status and quality of life (OHQOL - Oral Health and Quality of Life questionnaire) and daily performances (OIDP - Oral Impacts on Daily Performances questionnaire). Intra-group (baseline vs. 90 days) and inter-groups (at each experimental time) comparisons will be performed using the software Bio Estat 5.0 and SPSS 14.0. Expected results: to determine the efficacy of the mechanical-chemical therapy in subjects diagnosed with diabetes, obesity or diabetes + obesity. Also, to determine if these systemic conditions influence the response to periodontal treatment. Finally, it could be analyzed if these systemic conditions as well as the proposed therapy influence the self-detected quality of life and volunteers' daily performance. (AU)
