Kim: The association between periodontitis and systemic disease among Korean adults

Abstract

Objectives

Periodontal disease has developed not only as a localized factor of oral disease, but also as an important factor related to diabetes, cardiovascular disease, hypertension, and smoking. The aim of this study was to investigate the association between periodontitis and systemic disease by utilizing the representative national health nutrition survey in Korea.

Methods

Study participants without any missing data were selected from the sixth (2014) national health nutrition survey, which included 5,604 individuals with periodontal pocket depth. To determine that periodontal disease was associated not only with localized factors but with various factors interacting with each other, parameters such as hypertension, diabetes, heart disease, dyslipidemia, alcohol intake, smoking, age, level of education, income, regular visits to a dentist, frequency of toothbrushing, and presence of a dental cavity were investigated and evaluated anemic factors with CPITN. The associations were analyzed using the chi-square test and multiple logistic regression.

Results

Only hypertension was found to influence periodontitis independently [95% confidence interval: 0.6-0.9].

Conclusions

A statistically significant association between hypertension and periodontal disease was noted and this association is expected to be fundamental data for future studies.
