Relationship between self-rated pain and peri-implant clinical, radiographic and whole salivary inflammatory markers among patients with and without peri-implantitis

Abstract

Background: There are no studies that have evaluated the correlation between self-rated pain, peri-implant clinical and radiographic parameters (plaque index [PI], bleeding on probing [BOP], probing depth [PD], and crestal bone loss [CBL]) and whole salivary interleukin (IL)-1β, IL-6, and tumor necrosis factor-alpha (TNF-α) levels among patients with and without peri-implantitis. Purpose: The objective was to evaluate the correlation between self-evaluated pain, peri-implant clinical and radiographic parameters and whole salivary IL-1β, IL-6, and TNF-α levels among patients with and without peri-implantitis. Materials and Methods: Included in this study were patients with and without peri-implantitis. Data regarding age, gender, duration of implants in function, and self-perceived pain were recorded using a question. Self-rated pain was assessed using the numeric pain rating scale. Peri-implant PD, PI, BOP, and CBL were recorded and samples of unstimulated whole saliva samples were obtained. Whole salivary IL-1β, IL-6, and TNF-α were measured. Sample-size was approximated and group comparisons were completed. P-values
