Background: Peri-implant bleeding on probing is recognized as a clinical indication of inflammation in the surrounding tissues of the dental implant. It is an essential parameter for assessing and diagnosing peri-implant disease. Consequently, the management of factors associated with peri-implant bleeding on probing become a crucial goal in the maintenance care of dental implants. Objective: To identify factors associated with peri-implant bleeding on probing in single implant without bone loss Method: An observational cross-sectional study was conducted on patients with single implants that had been loaded for at least 1 year. Demographic data and previous relevant treatments were obtained from the dental records. Clinical examination of dental implants was performed by two trained and calibrated dentists, including assessment of oral hygiene status, probing pocket depth, keratinized tissue, and contact point. Peri-implant bleeding on probing was recorded at 6 sites per implant, indicating its presence or absence. Factors associated with bleeding were assessed using multilevel logistic regression. Result: Among 40 patients, a total of 67 implants were included, with an average age of 57.9gif.latex?\pm13.6 years. The study revealed an incidence of peri-implant bleeding on probing at the site level of 67.7% (95% CI: 62.8, 72.2%). Factors such as poor oral hygiene, increased probing pocket depth and the presence of a metal crown on the implant were found to be significantly associated with higher risk, with adjusted odds ratios of 14.94, 1.80 and 8.75 respectively. Conclusion: Peri-implant bleeding on probing in single implant without bone loss is a common clinical condition and is associated with oral hygiene status, probing pocket depth and the type of implant crown. Therefore, it is essential to consider managing these factors to reduce the occurrence of peri-implant bleeding on probing, which a critical clinical indicator of peri-implant mucositis, which has the potential to progress into peri-implantitis.
