Its first stage is the mechanical removal of dental plaque along with the control of risk factors. Subgingival mechanotherapy, also known as scaling and root planing (SRP) is the next stage, aimed at the subgingival area. Perioscopy makes possible direct real-time visualization of the root surface during the procedure. The research results published so far indicate improvement or no significant differences clinical parameters after SRP procedure using a perioscope vs traditional subgingival instrumentation. The aim of this study is to indicate, or not, clinical, biochemical (level of pro-inflammatory cytokines) and microbiological (A. actinomycetemcomitans, P. gingivalis, T. denticola) differences after periodontitis treatment using the traditional method vs. using a perioscope.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '60 Years', 'minimumAge': '20 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* age 20-60; (II)\n* preserved lateral and anterior teeth;\n* no periodontal treatment in the last 12 months;\n* intermediate or advanced periodontitis (Stage II / III / IV)\n* in each quadrant at least three teeth with PPD\\>5 mm after initial treatment (scaling, motivation, instruction)\n\nExclusion Criteria:\n\n* antibiotic therapy in the last 6 months;\n* smoking;\n* systemic diseases affecting periodontal tissues;\n* pregnancy or lactation;\n* orthodontic treatment;\n* tooth mobility II / III degree;\n* involvement of third degree furcations according to Hamp classification;\n* endodontic issues'}, 'identificationModule': {'nctId': 'NCT06366295', 'briefTitle': 'Comparison of Subgingival Mechanotherapy With and Without the Use of a Perioscope: Clinical Trial', 'organization': {'class': 'OTHER', 'fullName': 'Medical University of Warsaw'}, 'officialTitle': 'Subgingival Mechanotherapy Using a Periodontal Endoscope Compared to Classical Subgingival Mechanotherapy for the Treatment of Periodontitis: a Randomized Clinical Trial', 'orgStudyIdInfo': {'id': 'WUM.Perio.05'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Subgingival mechanotherapy with perioscopy', 'description': 'Scaling and root planing using ultrasonic scaler and curettes, under the control of a perioscope, enabling real-time, magnified imaging of the root surface.', 'interventionNames': ['Device: subgingival mechanotherapy with perioscopy']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Classical subgingival mechanotherapy', 'description': 'Scaling and root planing using ultrasonic scaler and curettes.', 'interventionNames': ['Device: classical subgingival mechanotherapy']}], 'interventions': [{'name': 'subgingival mechanotherapy with perioscopy', 'type': 'DEVICE', 'description': 'Subgingival mechanotherapy using a machine scaler, curettes and a perioscope', 'armGroupLabels': ['Subgingival mechanotherapy with perioscopy']}, {'name': 'classical subgingival mechanotherapy', 'type': 'DEVICE', 'description': 'Subgingival mechanotherapy using a machine scaler and curettes', 'armGroupLabels': ['Classical subgingival mechanotherapy']}]}, 'contactsLocationsModule': {'locations': [{'zip': '02-097', 'city': 'Warsaw', 'state': 'Masovian Voivodeship', 'status': 'RECRUITING', 'country': 'Poland', 'contacts': [{'name': 'Bartlomiej Gorski, DDS, PhD', 'role': 'CONTACT', 'email': 'bartlomiej.gorski@wum.edu.pl', 'phone': '+48 22 502 20 99'}], 'facility': 'Department of Periodontology and Oral Mucosa Diseases, Medical University of Warsaw', 'geoPoint': {'lat': 52.22977, 'lon': 21.01178}}], 'centralContacts': [{'name': 'Karolina Grzywacka', 'role': 'CONTACT', 'email': 'k.grzywacka@gmail.com', 'phone': '+48796137960'}, {'name': 'Bartlomiej Górski, PhD', 'role': 'CONTACT', 'email': 'bartlomiej.gorski@wum.edu.pl', 'phone': '+48 22 116 64 31'}], 'overallOfficials': [{'name': 'Bartlomiej Górski, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Department of Periodontology and Oral Mucosa Diseases, Medical University of Warsaw'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Medical University of Warsaw', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
