Association between Cardiovascular Diseases and Peri-Implantitis: A Systematic Review and Meta-Analysis

Could the periodontal therapy improve the cardiologic patient health? A narrative review

BACKGROUND

Cardiovascular diseases (CVD) is the major cause of mortality globally, with increasing evidence suggesting a link between periodontitis, and CVD. This study aims to explore the association between periodontitis and CVD, and the impact of periodontal therapy on cardiovascular health.

METHODS

This review synthesized findings from preclinical and clinical studies, without publication year restrictions, examining periodontitis and CVD through various lenses. Scientific databases were inspected with keywords related to periodontitis and CVD.

RESULTS

The review identifies a substantial association between periodontitis and an increased risk of several CVD, supported by both epidemiological and interventional studies. Results suggest the complexity of the relationship, influenced by factors like the severity of periodontitis and the presence of other systemic conditions. Clinical data indicates that periodontal therapy, particularly non-surgical periodontal therapy, may reduce systemic inflammatory markers and thus may play a role in the primary and secondary prevention of CVD events, highlighting the potential of periodontal therapy to not only maintain oral health but also to modulate cardiovascular risk factors.

CONCLUSIONS

Current evidence supports a significant association between periodontitis and increased cardiovascular risk, promoting integrated healthcare approaches that consider oral health as a key-component of cardiovascular care and wellbeing.

Risk factors for Peri-implantitis: An umbrella review of meta-analyses of observational studies and assessment of biases

OBJECTIVES

To perform a comprehensive quantitative and qualitative analysis of the findings from previously published meta-analyses and to assess existing biases.

DATA/SOURCES

A search was conducted for meta-analyses of observational studies investigating the association between any risk factor and peri‑implantitis in PubMed, Scopus, Cochrane Database of Systematic Reviews, and Epistemonikos, from inception until October 2023 (PROSPERO: CRD42024512408).

STUDY SELECTION

From a total of 5002 publications, 51 full-text articles were evaluated for eligibility, and 12 articles that described 41 unique meta-analyses evaluating the association between risk factors and periimplantitis were selected. Among 41 associations, 24 associations were significant. None of the associations were graded as convincing evidence. Two associations, presence of periodontitis (OR = 3.84 [95 % CI 2.58,5.72]) and cigarette smoking (RR=2.07 [95 % CI 1.41,3.04]) were graded as highly suggestive. Eight associations, diabetes mellitus, hyperglycaemia, lack of prophylaxis, history of chronic periodontal disease, ongoing or history of periodontal disease, implants located in the anterior region of the jaw (maxillary and mandibular), osteoprotegerin (OPG) gene polymorphisms, and lack of keratinized mucosal width were graded as suggestive evidence.

CONCLUSIONS

Periodontitis and cigarette smoking are highly suggestive risk factors for peri‑implantitis. The remaining risk factors which are suggestive require more high-quality studies to be performed to upgrade the level of evidence.

CLINICAL SIGNIFICANCE

The highly suggestive and suggestive risk factors for peri‑implantitis summarized in this umbrella review should be rigorously assessed, monitored and managed by clinicians to reduce the risk peri‑implantitis, as well as to form part of the preoperative consent process.

The Impact of Peri-Implant Diseases on the General Status of Patients with Cardiovascular Diseases: A Literature Review

BACKGROUND AND OBJECTIVES

The aim of this study is to connect peri-implantitis to cardiovascular diseases, following the association found between periodontitis and cardiovascular conditions in recent years.

MATERIALS AND METHODS

PubMed, Scopus, Web of Science online databases were searched up to June 2023, with the exclusion criteria being research written in a language other than English. The MeSH search items were as follows: ["peri-implant health OR peri-implantitis OR peri-implant mucositis OR peri-implant disease"] AND ["cardiovascular diseases"]. Patient/population (P), intervention (I), comparison (C), outcome (O) framework questions were followed to identify the clinical evidence for the systematic review. Only clinical studies that used a control group to compare the relationship between cardiovascular diseases and peri-implantitis were selected.

RESULTS

A total of 118 studies were identified through electronic search of the keywords. After removing duplicates, there were 76 records to be screened. Upon exclusion of ineligible titles and abstracts, 27 studies remained for evaluation. Finally, 23 studies were excluded for not meeting the inclusion criteria, leaving 4 studies to be included in the qualitative analyses.

CONCLUSIONS

This study found there is a linear association between mucosal/gingival inflammation and carotid intima-media thickness test (c-IMT) values. Peri-implant mucosal inflammation could be a contributor to the vascular disease burden of an individual; further specific clinical studies should be performed in order to demonstrate this connection.
