This study aims to evaluate the bidirectional associations between periodontitis and IBD through a systematic review and meta-analysis. Five databases (PubMed, Embase, Web of Science, Scopus and Cochrane Library) were systematically searched from inception to 27 February 2024. Two independent reviewers performed a review of the retrieved studies. Longitudinal studies, including cohort and nested case–control studies, were considered eligible for the study design. The pooled risk ratio (RR) and hazard ratio (HR) derived from the meta-analysis were used to assess whether periodontitis (or IBD) was a risk factor for IBD (or periodontitis). Trial sequential analysis (TSA) was performed to evaluate the reliability of the results. Four studies (<i>n</i> = 10 270 912) on the risk of IBD in patients with periodontitis and two (<i>n</i> = 33 420) on the risk of periodontitis in patients with IBD were included. The result suggested that periodontitis did not increase the risk of IBD (pooled RR = 1.04, 95% confidence interval [CI]: 0.99–1.09; <i>p</i> = .164; I-squared statistic [<i>I</i>²] = 27%). For subtypes of IBD, periodontitis was associated with the occurrence of ulcerative colitis (UC) (pooled RR = 1.12, 95% CI: 1.04–1.21; <i>p</i> = .003; <i>I</i>² = 38%), but not with Crohn's disease (CD) (pooled RR = 0.98, 95% CI: 0.92–1.04; <i>p</i> = .475; <i>I</i>² = 0%). Specifically, the risk of UC was higher among men (pooled HR = 1.11, 95% CI: 1.01–1.22; <i>p</i> = .025; <i>I</i>² = 0%) and smokers (pooled HR = 1.23, 95% CI: 1.07–1.42; <i>p</i> = .004; <i>I</i>² = 0%) with periodontitis than their counterparts without periodontitis. Patients with IBD may have a higher risk of developing periodontitis (pooled HR = 1.37, 95% CI: 1.26–1.49; <i>p</i> &lt; .001; <i>I</i>² = 18%); however, whether IBD subtypes increased the occurrence of periodontitis remained uncertain. The TSA results confirmed the reliability of the primary findings. Based on limited longitudinal evidence, patients with periodontitis do not exhibit an increased risk of developing IBD overall, but they are at increased risk of UC (not CD). On the contrary, patients with IBD have a higher risk of developing periodontitis over time. More high-quality longitudinal studies are needed to determine the effect of specific subtypes of IBD on periodontitis.</p>","PeriodicalId":16715,"journal":{"name":"Journal of periodontal research","volume":"59 6","pages":"1083-1094"},"PeriodicalIF":3.4,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141261155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The protocol was registered in PROSPERO database (CRD42023485425). The focused PECO questions were as follows: (1) “In patients with periodontitis, undergoing periodontal treatment, are teeth affected by mobility at higher risk of being extracted/lost compared to non-mobile teeth, with a minimum follow-up of 10 years?” and (2) “In these patients, does varying degrees of tooth mobility increase the risk of tooth extraction/loss, with a minimum follow-up of 10 years?”. Results were reported according to PRISMA statement. Electronic and manual searches were conducted to identify longitudinal studies. The different assessments of tooth mobility were pooled into three groups: TM0: Undetectable tooth mobility, TM1: Horizontal/Mesio-distal mobility ≤1 mm, TM2: Horizontal/Mesio-distal mobility &gt;1 mm or vertical tooth mobility. Tooth loss was the primary outcome. Various meta-analyses were conducted, including subgroup analyses considering different follow-up lengths and the timing of TM assessment, along with sensitivity analyses. A trial sequential analysis was also performed. Eleven studies were included (1883 patients). The mean follow-up range was 10–25 years. The weighted total of included teeth, based on the sample size, was 18 918, with a total of 1604 (8.47%) extracted/lost teeth. The overall rate of tooth extraction/loss increased with increasing mobility: TM0 was associated with a 5.85% rate (866/14822), TM1 with the 11.8% (384/3255), TM2 with the 40.3% (339/841).

Supernatant concentrations (2.5 × 10⁷ and 5 × 10⁷ CFU/mL) significantly (<i>p</i> &lt; .05) decreased the production of <i>IL-1β</i>, <i>IL-6</i>, <i>IL-8</i>, and <i>TLR-</i>2 in the presence of LPS. In contrast, inflammatory markers were not reduced by <i>L. reuteri</i> supernatant in the presence of glucose.
