Aims: Periodontitis has been associated with an increased risk of cardiovascular events. The nature of the association is unclear because both periodontitis and cardiovascular disease (CVD) share a host of risk factors. Intervention trials are critical to explore the relationship. If the association were causal, successful periodontal therapy will lead to an attenuation of the effect – CVD.
Material and Methods: The paper reviewed the design and the results of intervention trials aimed at improving systemic inflammation, endothelial dysfunction, carotid atherosclerosis and cardiovascular events.
Results: Early systematic reviews and a definitive controlled clinical trial indicate that intensive periodontal therapy results in a decrease in systemic inflammation and an improvement of endothelial dysfunction in systemically healthy subjects. A pilot trial has indicated the feasibility to assess the impact of periodontal therapy on carotid atherosclerosis in a primary cardiac prevention design.
Conclusions: Efforts to test causality in the relationship between periodontitis and CVD are ongoing. Evidence to date is consistent with the notion that severe generalized periodontitis causes systemic inflammation and endothelial dysfunction. Periodontitis has effects that go beyond the oral cavity and its treatment and prevention may contribute to the prevention of atherosclerosis.  相似文献

The association of gingivitis and periodontitis with ischemic stroke   总被引:2,自引:0,他引:2  
OBJECTIVES: The aim of this study was to assess the associations of different periodontal parameters with cerebral ischemia. METHODS: In a case-control study, 303 consecutive patients with ischemic stroke or transient ischemic attack, and 300 representative population controls received a complete clinical and radiographic dental examination. Patients were examined on average 3 days after ischemia. The individual mean clinical attachment loss measured at four sites per tooth was used as indicator variable for periodontitis. RESULTS: Patients had higher clinical attachment loss than population (p<0.001). After adjustment for age, gender, number of teeth, vascular risk factors and diseases, childhood and adult socioeconomic conditions and lifestyle factors, a mean clinical attachment loss >6 mm had a 7.4 times (95% confidence interval 1.55-15.3) a gingival index >1.2 a 18.3 times (5.84-57.26) and a radiographic bone loss a 3.6 times (1.58-8.28) higher risk of cerebral ischemia than subjects without periodontitis or gingivitis, respectively. CONCLUSION: Periodontitis is an independent risk factor for cerebral ischemia and acute exacerbation of inflammatory processes in the periodontium might be a trigger for the event of cerebral ischemia.  相似文献

Background: A number of epidemiologic studies were published that looked at the association between coronary heart disease (CHD) and periodontal disease. However, debate exists about whether this association is a true relationship or simply an example of an uncontrolled confounder. This retrospective cohort study examines the relationship between periodontal disease and CHD. Methods: Digital panoramic radiographs were used to assess alveolar bone loss (ABL) using a Schei ruler. Participants consisted of Veterans Administration (VA) patients who were eligible for dental benefits and had a digital panoramic radiograph taken at the VA Medical Center, Denver, Colorado. Information on CHD and other important clinical variables were obtained from electronic medical records. Results: The examination of the relationship between ABL and CHD revealed a significant non‐linear relationship with a threshold at ≈20% bone loss with a doubling of the probability ratios of CHD compared to those at 7.5% bone loss. Conclusions: To our knowledge, this is the first study to demonstrate a non‐linear relationship between ABL and CHD. A significant positive association between ABL and CHD was found at even low levels of bone loss between 10% and 20%.  相似文献

Objectives: To review the evidence for the association between diabetes and periodontal and peri-implant conditions and the impact of periodontal therapy in subjects with diabetes.
Material and Methods: A search of MEDLINE-PubMed was performed up to and including December 2007. The search was limited to clinical studies published in English. Publications on animal studies were excluded. The selection criteria included all levels of available evidence.
Results: Evidence on the association between diabetes and periodontitis supports the concept of increased severity but not extent of periodontitis in subjects with poorly controlled diabetes. Subjects with controlled diabetes do not show an increase in extent and severity of periodontitis. Periodontitis is associated with poor glycaemic control and diabetes-related complications. It is inconclusive that periodontal therapy with or without the use of antibiotics results in improvements of glycaemic control and of markers of systemic inflammation. Evidence is lacking to indicate that implant therapy in subjects with diabetes yields long-term outcomes comparable with those of non-diabetic subjects.
Conclusions: Poorly controlled diabetes may be considered a risk factor for increased severity of periodontitis. The effects of periodontal therapy on glycaemic control and systemic inflammation is not proven beyond doubt and need to be confirmed in large-scale randomized-controlled clinical trials.  相似文献

Periodontitis may be viewed as an infectious disease with a number of specific characteristics. Pathogens of the subgingival microbiota can interact with host tissues even without direct tissue penetration. Hence, antimicrobial agents must be available at a sufficiently high concentration not only within the periodontal tissues, but also outside, in the environment of the periodontal pocket. The subgingival microbiota accumulate on the root surface to form an adherent layer of plaque with the characteristics of a biofilm. Several mechanisms, such as diffusion barriers, and selective inactivation of agents lead to an increased resistance of bacteria in biofilms. Mechanical supragingival plaque control is indispensable to prevent the re-emergence of periodontal pathogens and the re-establishment of a biofilm in treated sites. Since specific features have important implications for the use of antimicrobial agents in periodontal therapy, extrapolations from experiences made in the therapy of other infections are only partially valid. The ultimate evidence for the efficacy of systemic or local chemotherapy must be obtained from treatment studies in humans with adequate follow-up.  相似文献

Biologic medications (BMs) are increasingly used for the management of systemic chronic inflammatory diseases. These diseases are often associated with a higher prevalence of apical periodontitis (AP) and periodontitis (P). The purpose of this systematic review was to ascertain the interactions between AP and/or P and BMs. The review was registered in the PROSPERO database (CRD42017054756). Electronic searches were performed on Pubmed Medline, Scopus and The Web of Science from their inception through to 20 March 2018. The references of the articles selected were checked. The keywords were chosen based on a pilot search, which aimed to find the most frequently prescribed BMs. The included studies were appraised qualitatively using appropriate tools. Thirty‐five articles met the inclusion criteria, comprising 16 non‐randomized clinical studies, 12 in vivo animal studies and 7 case reports. Quality of information was assessed as high in 18 articles, moderate in 16 articles and low in 1 article. BMs in patients suffering from chronic inflammatory diseases seems to inhibit the progression of AP and P, and to enhance the healing response to periodontal and endodontic treatment. A healthier condition of the periodontal tissues seems to be associated with a better response of the patient to BMs therapy.  相似文献
