A systematic review and network meta-analysis of the association between periodontitis and inflammatory bowel diseases

ObjectivesSeveral earlier studies have shown that IBD (including its two subtypes, ulcerative colitis (UC) and Crohn's disease (CD)) increases the risk of periodontal disease. This study aimed to evaluate the relevance among periodontitis and IBD subcategories.MethodsThis study was conducted based on PRISMA guidelines. The Web of Science, PubMed, Google Scholar, and Scopus databases were searched up to February 2024 using pertinent keywords. Case series, review articles, and animal studies were excluded. The risk of bias in this research was evaluated through the Joanna Briggs Institute (JBI) criteria. The meta-analysis was conducted using R statistical software.ResultsA total of 9134 patients within 13 studies after the screening process were evaluated. Our study has shown that periodontitis is significantly more prevalent among IBD patients (UC and CD). According to prior meta-analyses, PD morbidity was found to be significantly high among CD patients (OR: 4.30; 95% CI: 3.72-4.98; I2 = 0%). Similarly, UC elevated PD risk (OR: 4.55; 95% CI: 3.76-5.50; I2 = 0%). The risk of periodontitis was not significantly different between CD and UC patients (OR: 0.96; 95% CI: 0.65-1.43; I2 = 34%).ConclusionsUC and CD patients were more likely to develop periodontitis, with low heterogeneity between studies, while the prevalence of periodontitis among UC and CD patients was not meaningfully different.Clinical relevanceThe higher risk of periodontitis in patients with IBD indicates the necessity of screening for periodontitis. Considering the various oral manifestations and poor quality of life associated with IBD, it is important to be aware of the symptoms of periodontitis.
