Kirjeldus
There will be a randomized clinical trial with patients from the outpatient clinic of Endocrinology - Prediabetes and outpatient dental clinic of the Faculty of Dentistry, UFRGS who have a diagnosis of metabolic syndrome and diagnosis of periodontitis. The clinical trial will consist of an arm where it will be immediately periodontal treatment (test group) and another arm which will be held later periodontal treatment (control group). The study will last for six months , and after this period, the control group will receive the same treatment to the test group .
A socio-demographic questionnaire will be applied by a trained interviewer , so that data on income, education , behavioral habits , medical and dental history. A questionnaire with some key questions will be repeated in 10 % of the sample within seven days after the first application in order to check the reproducibility of the instrument.
Complete periodontal examination will be conducted at 6 sites per tooth for all teeth present at baseline and 3 and 6 months after periodontal treatment. The examination will be conducted by two examiners trained and calibrated. There will be measured Probing Depth , Bleeding On Probing, Periodontal Attachment Loss , Gingival Bleeding Index , Visible Plaque Index and the retentive factors of plaque.
In addition to the tests required for the diagnosis of metabolic syndrome , will be did the same blood tests at 3 and 6 months after periodontal treatment (total cholesterol , LDL and HDL , fasting glucose , triglycerides , C-reactive protein) . Aliquots of plasma from blood collected in each experimental point are stored at -80 ° C for analysis of interleukin- 6, TNF- α , GLP-1 and adiponectin .
At each clinical examination will be collected gingival crevicular fluid , and subgingival biofilm above 4 sites randomized among those with higher probing depth at baseline. The sites of fluid collection will be properly insulated with cotton rolls and / or gauze and dried with air jets . From the introduction of rectangles of absorbent paper (Periopaper ) for 30 seconds will be held in the gingival sulcus fluid collection . Periopaper strips are analyzed for volume (Periotron 8000) and stored in sterile plastic tube at -80 ° C until analysis. The presence of Il- 1β , IL-6 and TNF- α in the gingival fluid will be identified by flow cytometry .
The supragingival plaque will be collected with sterile spoon dentin and subgingival plaque will be collected with a sterile paper cone inserted in selected sites for 30 seconds , after drying the surface and careful removal of supragingival plaque . The cones are stored in sterile plastic tube at -80 ° C until analysis. The identification of total bacterial load and microbial periodontal ( Porphyromonas gingivalis , Fusobacterium nucleatum , Prevotella intermedia and Streptpcoccus mitis ) will be performed using the technique of real -time PCR and T - RFLP .
Dental treatment will be performed by two periodontists who either ignore the data for examination of patients . The test group will receive nonsurgical periodontal treatment in 4 weeks. The treatment will include caries removal and sealing of cavities or caries restoration , removal of restorations maladaptive , extraction of residual roots , removal of supragingival calculus and subgingival scaling and root planing under local anesthesia . Instruction, training and motivation for oral hygiene will be addressed throughout treatment. Completed treatment , patients return to fortnightly visits to the 3 month and monthly until month 6 , where it will be professional removal of supra and subgingival biofilm , and oral hygiene instruction . In 3 and 6 months will also be repeated full mouth examination for both test and control groups .
The control group will receive information about periodontal disease, as well as an oral hygiene kit consisting of multicerdas toothbrush , toothpaste and interdental brush . The same treatment given to the test group will be held in the control group immediately after the 6-month assessment . The period of six months waiting for dental treatment for individuals in the control group is supported in the literature
