Derks J, Ichioka Y, Dionigi C et al. Prevention and management of peri-implant mucositis and peri-implantitis: a systematic review of outcome measures used in clinical studies in the last 10 years. J Clin Periodontol 2022; DOI: 10.1111/jcpe.13608. Online ahead of print.

PPD and BOP were routinely reported, while composite outcomes, adverse events and patient-reported outcomes were infrequently described.

This systematic review evaluated the outcome measures, methods of assessment and analysis in clinical studies on the prevention and management of peri-implant mucositis and peri-implantitis. Systematic electronic searches up to April 2021 were conducted to identify longitudinal clinical studies with ≥10 patients on either the prevention or management of peri-implant diseases. Outcome measures of this analysis were the choice of outcome measures, methods of assessment and analytical methods. Risk of bias was evaluated. The analysis of the 159 selected studies revealed that probing pocket depth (PPD) and bleeding/suppuration on probing (BOP) were reported in 89% and 87% of all studies, respectively. Additional outcome measures included plaque scores (reported in 64% of studies), radiographic outcomes (49%), soft tissue dimensions (34%) and composite outcomes (26%). Adverse events (8%) and patient-reported outcomes (6%) were rarely mentioned. A total of 36% of studies clearly defined a primary outcome measure.
