Abstract

Aim: The purpose of this study is to assess the associations between periodontal disease, tooth loss and liver diseases.

Materials and methods: PubMed and Embase databases were utilized to search eligible studies. Odds ratio (OR) with 95% confidence interval (CI) was used as effect size to assess the associations between periodontal disease, tooth loss and liver diseases risk.

Results: Our results indicated positive associations between periodontal disease and non-alcoholic fatty liver disease (NAFLD) (OR = 1.19, 95% CI = 1.06-1.33), liver cirrhosis (OR = 2.28, 95% CI = 1.50-3.48) and elevated transaminase level risk (OR = 1.08, 95% CI = 1.02-1.15). Moreover, tooth loss could increase NAFLD (OR = 1.33, 95% CI = 1.12- 1.56) and liver cancer risk (OR = 1.34, 95% CI = 1.04-1.74), and every five increment in tooth loss was associated with 5% increased liver cancer risk (OR = 1.05, 95% CI = 1.01 - 1.10) with a linear relationship. In addition, tooth loss had a positive tendency towards liver cirrhosis risk (OR = 2.03, 95% CI = 0.85-4.85) although there was no statistical significance.

Conclusion: Periodontal disease and tooth loss are positively associated with liver diseases including NAFLD, elevated transaminase level, liver cirrhosis and liver cancer.

Keywords: cirrhosis; liver cancer; non-alcoholic fatty liver disease; periodontal disease; tooth loss.
