Socioeconomic status and self-reported periodontal symptoms in community-dwelling individuals: data from the Korea Community Health Surveys of 2011 and 2013.

The severity of self-reported periodontal symptoms differed according to socioeconomic status. Subjects with lower socioeconomic status reported more advanced periodontal disease symptoms, such as gingival swelling, while those with higher socioeconomic status reported more incipient periodontal symptoms, such as gingival bleeding. Socioeconomic status remains a factor affecting self-reported periodontal symptoms in community-dwelling individuals in Korea.
