The study aims to assess patient perception of these diseases and their impact on quality of life through a cross-sectional observational study. Patients will be recruited from the Unit of Periodontics at "Le Scotte" University Hospital and will undergo diagnosis followed by questionnaire assessments. No follow-up visits are planned, and validated questionnaires will be administered to evaluate perception and impact on quality of life. Study procedures will include recording biometric peri-implant parameters and administering questionnaires such as the Brief Illness Perception Questionnaire (BIPQ) and Oral Health Impact Profile-14 (OHIP-14).', 'detailedDescription': 'Peri-implant diseases are inflammatory processes, influenced by biofilm, affecting the soft and hard tissues surrounding dental implants. They encompass two main conditions: peri-implant mucositis and peri-implantitis. While professional biofilm removal, coupled with plaque control, is considered the gold standard treatment, its efficacy is limited. Therefore, enhancing prevention and early diagnosis strategies for peri-implant complications is crucial. Despite extensive research on patient perception of periodontitis symptoms, little attention has been given to the symptoms and perception of peri-implant diseases and their impact on oral health-related quality of life. This observational study aims to assess patient perception of peri-implant diseases and their impact on oral health-related quality of life (OHRQoL). The study is a cross-sectional observational study. Patients will be recruited from the Unit of Periodontics, Department of Medical Biotechnologies, at "Le Scotte" University Hospital. Following diagnosis of peri-implant disease, patients meeting inclusion and exclusion criteria specified in the protocol will be included. Given the study\'s cross-sectional nature, no follow-up visits are planned. Validated questionnaires regarding the perception and impact on the quality of life of peri-implant diseases will be administered. Study procedures will include recording biometric parameters extracted from a complete periodontal examination and administering questionnaires on the perception and impact on the quality of life of peri-implant diseases: Brief Illness Perception Questionnaire (BIPQ) and Oral Health Impact Profile-14 (OHIP-14).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '18 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Patients will be recruited consecutively from those attending the Unit of Periodontics, Departoment of Medical Biotechnologies, at "Le Scotte" University Hospital (Siena, Italy).', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age between 18 and 70 years old;\n* Presence of at least one dental implant;\n* Presence of bleeding and/or suppuration upon probing of the peri-implant mucosa;\n* Ability and willingness to provide written consent for participation in the study.\n\nExclusion Criteria:\n\n* Pregnancy or breastfeeding status;\n* Patients unable to communicate in Italian or English;\n* Inability to perform proper oral hygiene maneuvers;\n* Inability or unwillingness to provide written consent for participation in the study.'}, 'identificationModule': {'nctId': 'NCT06383351', 'briefTitle': "Patients' Illness Perception of Peri-implant Diseases.
