1) Summarise your work in one sentence.
We analyzed the risk of future cardiovascular events according to oral health status and oral hygiene care.

2) Summarise your findings in one sentence.
Better oral hygiene behaviours are associated with lower cardiovascular risk.

3) Which were the more important methods you used in this work? If it is not a traditional method you can briefly explain the concept of that methodology.
Nationwide claims data (National Health Insurance System-National Health Screening Cohort, NHIS-HEALS) were used in this study. Studies using claims data are not new to researchers these days. One of the advantages of the cohort was that it includes health check-up data such as oral screening and self-reported questionnaires on lifestyle factors.
 
4) What did you learn from this paper, what was your take-home message?
We are excited that we are working on a novel "lifestyle". Lifestyle modifications for cardiovascular prevention include healthy diet, regular exercise, maintenence of ideal body weight, smoking cessation, and alcohol moderation. This study proposes that better oral hygiene behavior may become one of the healthy lifestyles. However, we still need higher-quality evidence such as prospective randomized controlled trials.
