Periodontitis has been independently associated with the chronic noncommunicable diseases that most frequently lead to death worldwide. The aim of the present systematic review was to study whether people with periodontitis/edentulism are at increased risk of all-cause and cause-specific mortality as compared with those without periodontitis/edentulism. Cohort studies were included that 1) evaluated periodontitis or edentulism as exposures in relation to all-cause or cause-specific mortality as an outcome and 2) reported effect estimates as hazard ratios, risk ratios, or odds ratios with 95% CIs or crude numbers. Two review authors independently searched for eligible studies, screened the titles and abstracts, did full-text analysis, extracted the data from the published reports, and performed the risk-of-bias assessment. In case of disagreement, a third review author was consulted. Study results were summarized through random effects meta-analyses. A total of 57 studies were included, involving 48 cohorts and 5.71 million participants. Periodontitis was associated with increased risk of all-cause mortality (risk ratio, 1.46 [95% CI, 1.15 to 1.85]) and mortality due to cardiovascular diseases (1.47 [1.14 to 1.90]), cancer (1.38 [1.24 to 1.53]), coronary heart disease (2.58 [2.20 to 3.03]), cerebrovascular diseases (3.11 [2.42 to 3.98]), but not pneumonia (0.98 [0.69 to 1.38]). Edentulism (all types) was associated with increased risk of all-cause mortality (1.66 [1.46 to 1.88]) and mortality due to cardiovascular diseases (2.03 [1.50 to 2.74]), cancer (1.55 [1.24 to 1.94]), pneumonia (1.72 [1.07 to 2.78]), coronary heart disease (2.98 [2.43 to 3.65]), and cerebrovascular diseases (3.18 [2.24 to 4.51]). Periodontitis and its ultimate sequela (edentulism) are associated with an increased risk of all-cause and cause-specific mortality (PROSPERO CRD42018100095).

Abstract
Periodontitis has been independently associated with the chronic noncommunicable diseases that most frequently lead to death worldwide. The aim of the present systematic review was to study whether people with periodontitis/edentulism are at increased risk of all-cause and cause-specific mortality as compared with those without periodontitis/edentulism. Cohort studies were included that 1) evaluated periodontitis or edentulism as exposures in relation to all-cause or cause-specific mortality as an outcome and 2) reported effect estimates as hazard ratios, risk ratios, or odds ratios with 95% CIs or crude numbers. Two review authors independently searched for eligible studies, screened the titles and abstracts, did full-text analysis, extracted the data from the published reports, and performed the risk-of-bias assessment. In case of disagreement, a third review author was consulted. Study results were summarized through random effects meta-analyses. A total of 57 studies were included, involving 48 cohorts and 5.71 million participants. Periodontitis was associated with increased risk of all-cause mortality (risk ratio, 1.46 [95% CI, 1.15 to 1.85]) and mortality due to cardiovascular diseases (1.47 [1.14 to 1.90]), cancer (1.38 [1.24 to 1.53]), coronary heart disease (2.58 [2.20 to 3.03]), cerebrovascular diseases (3.11 [2.42 to 3.98]), but not pneumonia (0.98 [0.69 to 1.38]). Edentulism (all types) was associated with increased risk of all-cause mortality (1.66 [1.46 to 1.88]) and mortality due to cardiovascular diseases (2.03 [1.50 to 2.74]), cancer (1.55 [1.24 to 1.94]), pneumonia (1.72 [1.07 to 2.78]), coronary heart disease (2.98 [2.43 to 3.65]), and cerebrovascular diseases (3.18 [2.24 to 4.51]). Periodontitis and its ultimate sequela (edentulism) are associated with an increased risk of all-cause and cause-specific mortality (PROSPERO CRD42018100095).
