Assessment of the relationship between periodontal disease and cardiovascular disorders: a questionnaire-based study

Abstract

Background and aimsPeriodontitis is an inflammatory disease, characterized by the loss of connective tissue and alveolar bone. There is an increasing evidence that periodontitis is associated with a number of chronic diseases. The aim of this study was to analyze the correlation between periodontitis and certain systemic diseases by identifying their risk factors in a population from North-West Romania.MethodsA questionnaire-based study was conducted on participants ≥45 years of age in 4 dentistry or family medicine practices from the Cluj and Bihor counties, Romania, over a time frame spanning two months. The interviewer-administered questionnaire included 42 items assessing risk factors for periodontal and cardiovascular disease, current diagnostic and medical treatment of the participants, their diet and oral hygiene habits.ResultsOf 108 participants included in the study, 63 (58.3%) declared a previous diagnosis of periodontitis. A significant difference was observed between the participants with declared diagnosis of periodontitis (PD+) and participants without declared diagnosis of periodontitis (PD−) for fresh fruit consumption (p=0.01) and increased sport activity (p=0.009). A significant difference between groups was observed in the case of smoking duration (p=0.047), participants with >10 years of smoking were more likely to declare a diagnosis of periodontitis. Also, PD+ participants were more likely to have a family history of periodontal disease (p<0.001). Multivariate analyses suggested periodontitis as a predictive variable for atherosclerotic coronary artery disease with an OR of 4.85 (95% confidence interval 1.01–23.29, p=0.049).ConclusionOur study found a statistically significant association between periodontal disease and a known family history of periodontal disorders and smoking duration. Daily intake of fresh fruit and increased sport activities were found to be protective factors against periodontal disease, while periodontitis was found as a risk factor for atherosclerotic cardiovascular disease.

Oral Mucoadhesive Buccal Film of Ciprofloxacin for Periodontitis: Preparation and Characterization

“…The ligature was left in place for 14 days as a gingival irritant and resulted in the development of plaque and periodontitis. The animals were kept in a uniform environment for 14 days and were checked daily to evaluate the suture, food and water intake, and body weight [15,16].…”

Association between life’s essential 8 and periodontitis: a study based on NHANES 2009–2014

“…Common risk factors for both diseases include increasing age, smoking, alcohol misuse, ethnicity, education and socioeconomic status, male gender, diabetes, and obesity. Several cross-sectional studies, case analyses, and epidemiological investigations indicate a significant correlation between chronic periodontitis and cardiovascular disease (8)(9)(10)(11).…”

Effect of experimental periodontitis on cardiac functions: a comprehensive study using echocardiography, hemodynamic analysis, and histopathological evaluation in a rat model

“…At the molecular level, cases of active periodontitis exhibit an inflammatory response that can disrupt the overall homeostasis of the individual. This systemic inflammatory reaction may extend to areas beyond the oral cavity (7). Considering the systemic ramifications of periodontal disease, it undeniably wields a substantial influence on overall health, potentially exerting a profound impact on an individual's quality of life (8,9).…”
