However, some essential issues associated with the use of these antibiotics remain to be established. Although these agents are often prescribed after the healing phase of the SRP procedure, there is biological plausibility to support its use in conjunction with the mechanical treatment. However, to date, no placebo controlled randomized clinical trial (RCT) has directly compared these two protocols. Therefore, the aim of this multicentric RCT is to compare the clinical, microbiological and immunological effects of adjunctive systemic MTZ+AMX administered in different phases of the treatment of generalized chronic periodontitis (GChP). 180 subjects with GChP will be randomly assigned into three groups (n=60/group) that will receive SRP-only (control group) or in combination with 400 mg MTZ+500 mg AMX beginning at the first SRP session (group test 1) or after 3 months of its completion (group test 2). All volunteers will receive clinical and microbiological evaluation at baseline, 3, 6 and 12 months, and immunological assessment (levels of 20 chemokines) at baseline and 12 months post-therapy. Nine subgingival biofilm samples will be collected by subject and analyzed for counts and proportions of 40 bacterial species by checkerboard DNA-DNA hybridization. Differences in clinical, microbiological and immunological parameters among groups and over time will be evaluated using the ANOVA, ANCOVA, Chi-square and Tukey tests. Microbiological analyzes will be performed using adjustments for multiple comparisons. Statistical significance will be set at 5%.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '35 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* ≥35 years of age;\n* at least 15 teeth (excluding third molars and teeth with advanced decay indicated for extraction);\n* a minimum of 6 teeth with at least one site each with probing depth (PD) and clinical attachment level (CAL) ≥5 mm;\n* at least 30% of the sites with PD and CAL ≥4 mm and bleeding on probing (BOP).\n\nExclusion Criteria:\n\n* pregnancy;\n* breastfeeding;\n* current smoking and former smoking within the past 5 years;\n* systemic diseases that could affect the progression of periodontitis (e.g. diabetes, immunological disorders, osteoporosis);\n* scaling and root planing an in the previous 6 months;\n* antibiotic therapy in the previous 6 months;\n* long-term intake of anti-inflammatory medications;\n* need for antibiotic pre-medication for routine dental therapy;\n* use of orthodontic appliances;\n* extensive dental prosthetic rehabilitation;\n* allergy to metronidazole and/or amoxicillin.'}, 'identificationModule': {'nctId': 'NCT02954393', 'acronym': 'MOMENT', 'briefTitle': 'Amoxicillin and Metronidazole During Periodontal Treatment', 'organization': {'class': 'OTHER', 'fullName': 'University of Guarulhos'}, 'officialTitle': 'Influence of Moment of Systemic Metronidazole and Amoxicillin Administration in the Treatment of Chronic Periodontitis: a Randomized Clinical Trial.', 'orgStudyIdInfo': {'id': 'CAAE: 32465714.4.1001.5506'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'PLACEBO_COMPARATOR', 'label': 'Control', 'description': 'Scaling and root planing + Placebos active phase thrice a day (TID) for 14 days and Placebos healing phase TID for 14 days.', 'interventionNames': ['Procedure: Scaling and root planing', 'Drug: Placebos active phase', 'Drug: Placebos healing phase']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Active phase', 'description': 'Scaling and root planing + Metronidazole active phase (400 mg/thrice a day,TID) + Amoxicillin active phase (500 mg/ TID) for 14 days and Placebos healing phase TID for 14 days.', 'interventionNames': ['Procedure: Scaling and root planing', 'Drug: Metronidazole active phase', 'Drug: Amoxicillin active phase', 'Drug: Placebos healing phase']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Healing phase', 'description': 'Scaling and root planing + Placebos active phase thrice a day (TID) for 14 days and Metronidazole healing phase (400 mg/TID) + Amoxicillin healing phase (500 mg/TID) for 14 days.', 'interventionNames': ['Procedure: Scaling and root planing', 'Drug: Metronidazole healing phase', 'Drug: Amoxicillin healing phase', 'Drug: Placebos active phase']}], 'interventions': [{'name': 'Scaling and root planing', 'type': 'PROCEDURE', 'otherNames': ['SRP'], 'description': 'SRP will be performed in four to six appointments lasting approximately 1 h each, using manual curettes (Hu-Friedy, Chicago, IL, USA) and ultrasonic device (Cavitron Select SPC, Dentsply professional, York, PA, USA) under local anesthesia.
