简要总结
The aim of this randomized controlled clinical trial of superiority will be to evaluate the effect of 3 g of omega-3 polyunsaturated fatty acids and 100 mg of aspirin daily supplementation over a period of 180 days as adjunct to surgical therapy of residual pockets from patients with generalized aggressive periodontitis. Probing depth, clinical attachment level, gingival index and concentration of microorganisms and cytokines at baseline, 3, and 6 months after the procedure will be evaluated.
详细描述
The study is designed as a prospective, interventional, parallel, blinded, randomized, controlled clinical trial clinical of superiority, with a 6 month follow-up. The methodology of the present study will follow the standards of CONSORT-STATEMENT 2010 (Moher et al., 2010) and SPIRIT 2013 (Chan et al., 2013) for randomized clinical trials.
Source of data The population will be composed of patients diagnosed with generalized aggressive periodontitis (GAgP) recruited at Institute of Science and Technology - Unesp, in São José dos Campos / SP, who have already undergone non-surgical periodontal treatment and still have pockets with probing depth ≥5 mm and bleeding on probe.
Sample size Sample size calculation was performed using Sealed EnvelopeTM software. For this study, a population of 34 patients will be included. Considering α = 5% and β = 5% (power of 95%) to detect a change of at least 1 mm in clinical attachment level between groups, to a standard deviation of 0.8 mm, 17 patients will be required in each group
Clinical Parameters All clinical parameters will be assessed by a single blinded, trained and calibrated examiner (CFA) before surgical therapy (baseline) and at 3 and 6 months after using a manual probe. Measurements will be done at six sites per tooth (mesiobuccal, buccal, disto-buccal, distolingual, lingual, and mesiolingual) in all teeth, except third molars.
The following clinical parameters will be evaluated: 1) Full-mouth plaque index (PI); 2) Bleeding on probing (BoP); 3) Probing depth (PD): distance from the bottom of sulcus/pocket to gingival margin; 4) Gingival recession (GR): distance from the free gingival margin to cement-enamel junction (CEJ); 5) Clinical attachment level (CAL): distance from bottom of sulcus/pocket to the CEJ. The CEJ will be identified by careful probe on cervical area.
