This systematic review investigates the probable effect of proton pump inhibitor (PPI) use on the severity of periodontal disease and peri-implantitis and implant survival. We conducted a literature search in PubMed, Scopus, and Cochrane Central Library up to April 2024. Two review authors independently screened the title and abstracts and then the full texts of retrieved studies. Observational and clinical trial studies that assessed the association between PPIs use and periodontal disease severity and peri-implantitis or implant survival were included. Data extraction from the included studies was done by two reviews independently. Of 940 studies initially retrieved from online searching, 7 research met the inclusion criteria. Three studies examined periodontitis, while four focused on peri-implantitis and implant longevity. On the contrary, evidence regarding the impact of PPIs use on peri-implantits and implant survival is conflicting. Therefore, more well-designed RCTs are warranted to come to a definite conclusion. Since proton pump inhibitors alter the gut microbiome, and affect bone, plus the pathogenesis and etiology of periodontal disease are affected by bacteria within the periodontal pocket, it is hypothesized that they may affect periodontal pathogenesis.
