Introduction:
The current evidence linking tooth loss and cardiovascular disease mortality is inconclusive. Thus, the aim of this systematic review was to explore the association between tooth loss and cardiovascular disease (CVD) mortality.
Methods:
A comprehensive literature search of databases and gray literature included: Web of Science, Scopus, PubMed, Cochrane Central Register of Controlled Trials, Google Scholar, various digital repositories. The included studies reported on CVD mortality and tooth loss. The Newcastle-Ottawa scale was used to assess the quality of included studies. Random-effects meta-analysis method, sub-group analysis (based on the tooth loss categories (edentulous and fewer than 10 teeth present), meta-regression (based on the number. of confounders), publication bias, and sensitivity analysis were performed.
Results:
Twelve articles met the eligibility criteria with an overall "Good" quality. A significant association between tooth loss (edentulous or less than 10 teeth present) and CVD mortality was found in the primary meta-analysis, which compiled data from 12 studies. The estimated hazard ratio was 1.66 (95% CI: 1.32-2.09), and there was high heterogeneity (I2 = 82.42). Subgroup analysis revealed that the edentulous subgroup showed a higher risk with no significant heterogeneity, while the subgroup with fewer than 10 teeth showed a higher risk with substantial heterogeneity. Meta-regression analysis did not reveal any significant impact (P = .626) on whether variations in the number of confounders across studies would substantially affect the overall findings. No publication bias was detected and the sensitivity analysis based on the critical confounders also confirmed that tooth loss as a risk factor for CVD mortality (hazard ratio = 1.52, 95% CI: 1.28-1.80), (I2 51.82%).
Conclusion:
The present systematic review reported that being edentulous or having lesser than 10 teeth is a predictive indicator of CVD mortality.
