Patients' Illness Perception of Peri-implant Diseases. A Cross-sectional Study

NCT06383351 | Completed

• 1 other identifier: BQ001
• Study Type: observational
• Target: 148
• Locations: 1 country
• Sites: 1

Brief Summary

Despite extensive research on periodontitis, little attention has been given to the symptoms and perception of peri-implant diseases and their impact on oral health-related quality of life. 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).

Conditions

Peri-implant Mucositis; Perception; Survey; Questionnaires; Peri-Implantitis

Outcome Measures

Primary Outcomes (2)

• Assessment of patient's perception of their peri-implant disease through the Brief Illness Perception Questionnaire (Brief IPQ)

  Brief Illness Perception Questionnaire consists of 9 questions, each one evaluated on a scale of 0 to 10 (minimum score of 0, maximum score of 90). Higher scores mean a higher patient's perception of the disease (higher scores mean worse outcome).

  Baseline

• Assessment of peri-implant disease's impact on the oral health-related quality of life through the Oral Health Impact Profile 14.

  14 questions about the impact of oral health on the quality of life; each question will be evaluated on a scale of 1 to 5 (minimum score of 0, maximum score of 70). Higher scores mean that patient's oral health impacts more significantly on their quality of life (higher scores, worse outcomes).

  Baseline

Study Arms (1)

Peri-implant disease patients

Patients with a diagnosis of peri-implant mucositis or peri-implantitis

Other: Questionnaire

Interventions

Questionnaire OTHER

Two sets of questionnaires will be administered to patients: * Questionnaire about their perception of peri-implant disease (Brief Illness Perception Questionnaire; 9 questions, answers will be registered on a scale of 0 to 10); * Oral Health Impact Profile 14 (OHIP-14) questionnaire.
