Background: The aim of this case series/control study is to investigate the presence of the Advanced Glycation End products (AGEs) and oxidative stress in periimplantitis.
Findings: The Western Blotting analysis on periimplantitis and periodontal disease tissues showed marked increase of AGEs when compared to healthy control tissues. Also TBARS assay of whole saliva confirmed the expectations, showing higher oxidative stress levels in periimplantitis and periodontitis groups than in healthy group.
Conclusions: With the limitation of the sample size, these results showed that oxidative stress could be involved in the aetiology of periimplantitis. This hypothesis could lead to new therapeutic strategies in periimplantitis, using antioxidant approach in addition to conventional treatments.
