Objectives: Cardio-cerebrovascular diseases (CVDs) are the leading cause of death in advanced countries due to their upward-trending incidence rates. Preventing CVDs is imperative to ensure a healthy elderly life and prepare for an aging society. Considering the relationship between oral health and systemic health, effective oral health management will have an important role in preventing CVDs. This study aimed to examine the influence of oral health behaviors as risk factors for CVDs. Methods: A custom database combining data from the Korean National Health Insurance Service and the Korea National Health and Nutrition Examination Survey from 2010 to 2017 was analyzed. The study included participants aged 35 or over (n=14,492) with recorded responses on oral health behaviors. Logistic regression analyses were performed to assess the association between oral health behaviors and CVDs. Results: The CVDs group was shown to practice inappropriate oral health management. In comparison to the non-CVDs group, the CVDs group showed a significantly higher rate of 8.0% in ‘once or less’ of toothbrushing frequency (P<0.001). Moreover, the percentage of individuals who did not use oral hygiene supplements was 13.8% higher (P<0.001). Multiple logistic regression analysis revealed that the ‘use of dental floss and/or interdental brush’ was associated with a 16% lower risk for CVDs (P<0.05). Additionally, ‘twice’ and ‘three or more’ of toothbrushing frequency were associated with a 19% and 23% lower risk for CVDs, respectively (P<0.05). Conclusions The frequency of daily toothbrushing and the utilization of dental floss or interdental brush were significantly associated with CVDs. Therefore, there is a need to consistently emphasize the relationship between oral health and systemic diseases, along with the importance of oral hygiene management.

Objectives: This study aimed to investigate the association between oral health behaviors and dental scaling to suggest effective preventive oral health behaviors. Methods: This cross-sectional survey examined linked datasets derived from the Korean National Health Insurance Service and Korean National Health and Nutrition Examination Survey, 2014-2017. The data of 4,258 adults aged ≥19 years were included. A multivariate regression analysis was performed to evaluate the effect of oral health behaviors on willingness to undergo dental scaling. Results: The multivariate regression analysis revealed that the participants whose oral hygiene habits included a thrice-daily tooth brushing frequency were 1.5% more likely to undergo dental scaling (95% confidence interval [CI], 1.167-1.881) than the others. Furthermore, those whose oral hygiene habits included a thrice-daily tooth brushing frequency and the daily use of dental floss or an interdental brush were 1.6% more likely to undergo dental scaling (95% CI, 1.194-2.032) than their counterparts. Conclusions The group with the most favorable oral health behaviors underwent dental scaling more frequently. Better personal oral health habits may lead to willingness to undergo dental scaling, and incremental dental hygiene improvements can be achieved through further oral health education. Educational programs are needed to raise awareness of and promote improvements in individual oral health behaviors.

Purpose: Missing teeth is one of the most important indicators of oral health behavior and the result of dental caries, periodontal disease, and injuries. This study examined a trend in the incidence of severe partial edentulism (SPE) using the Korean National Health Insurance Service (KNHIS) data. Materials and Methods: Data of adults aged ≥20 years were obtained from the KNHIS for the 2014–2018 period. SPE was defined in dental information within a population with a treatment history of dental scaling as having 1 to 8 natural teeth. Crude incidence rates (CIRs) and age-standardized incidence rates (AIRs) with 95% confidence interval were calculated per 100000 persons. The Cochran Armitage trend (CAT) test and average annual percentage change were used to analyze SPE trends. Results: The CIRs among Korean adults were from 346.29 to 391.11 in 2014–2016 and from 391.11 to 354.09 in 2016–2018. The AIRs trend statistically increased by 4.31% from 346.29 to 376.80 and decreased by 4.72% from 376.80 to 342.10. The AIRs in men increased by 4.00% and decreased by 3.01%. The AIRs in women decreased by 2.18% and increased by 2.11% (CAT; p<0.01). The AIRs by region and income also showed trends of increase and decrease. Conclusion The study showed that the incidence trend of SPE increased and decreased from 2014 to 2018. This result would be able to aid in the planning of public oral health, and may also serve as fundamental data for verifying the impact of the public oral health policies implemented.
