The present study was aimed to investigate the prevalence of root caries and to determine significantly associated indicators with it among adults.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>The residents aged 35\u201374 years old were enrolled in a cross-sectional study in which dental examination were taken and structured questionnaires were collected in Zhejiang Province, China. All data were recorded in an electronic system and analyzed.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>The prevalence of decayed and filled root caries in 1,076 respondents was 31.9%. Elder age, greater attachment loss, and exposed root surface were associated with higher odds of incidence for decayed\/filled roots and decayed roots. In the last 12 months, 27.4% of adults with decayed or filled roots and 23.2% of others utilized oral health services. Carious adults who had a very poor\/poor oral health status were 2.905 times likely to report dental visits. People with sound roots who were female (OR = 2.103, <jats:italic>P<\/jats:italic> &lt; 0.001), perceived their oral health status as moderate (OR = 1.802, <jats:italic>P<\/jats:italic> = 0.015), or poor\/very poor (OR = 4.103, <jats:italic>P<\/jats:italic> &lt; 0.001) were more likely to visit a dentist in the past 12 months.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Age, attachment loss and root exposure were most significantly associated with the prevalence of root caries.
