Overview
Brief Summary
This study examines the association between psychosocial stress and peri-implant diseases. Peri-implant diseases are inflammatory conditions affecting the tissues around dental implants and may contribute to implant failure. Stress-related hormones, including cortisol and dehydroepiandrosterone (DHEA), may influence inflammatory responses in peri-implant tissues.
In this study, peri-implant sulcular fluid samples are collected from patients with peri-implant health, peri-implant mucositis, and peri-implantitis. Levels of cortisol, DHEA, and interleukin-6 (IL-6) are analyzed. Anxiety and depression levels are assessed using standardized questionnaires, and clinical peri-implant parameters are recorded.
The purpose of this study is to evaluate the relationship between stress-related biomarkers, psychological status, and peri-implant health and disease.
Detailed Description
Peri-implant diseases are inflammatory conditions affecting the soft and hard tissues surrounding dental implants and represent a major cause of implant failure. Psychosocial stress is known to influence immune function through activation of the hypothalamic-pituitary-adrenal (HPA) axis, resulting in altered secretion of stress-related hormones such as cortisol and dehydroepiandrosterone (DHEA). These hormonal changes may modulate inflammatory processes in peri-implant tissues.
This cross-sectional clinical study included 62 patients with dental implants, who were divided into three groups based on clinical and radiographic criteria: peri-implant health (PH, n=18), peri-implant mucositis (PM, n=22), and peri-implantitis (PI, n=22). Depression and anxiety levels were assessed using the Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI).
Clinical peri-implant parameters, including plaque index, gingival index, bleeding on probing, probing depth, clinical attachment level, and keratinized tissue width, were recorded. Marginal bone loss was evaluated using standardized periapical radiographs. Peri-implant sulcular fluid samples were collected and analyzed for cortisol, DHEA, and interleukin-6 (IL-6) levels using enzyme-linked immunosorbent assay (ELISA). Biomarker results were expressed as both concentration and total amount.
The study evaluates the associations between psychosocial stress markers, inflammatory biomarkers, and clinical peri-implant parameters to better understand the psychoneuroimmunological mechanisms involved in peri-implant diseases.
