Results of multiple logistic regression showed that number of teeth, DMF\u2010S scores, sex, and socio economic factors were statistically significantly associated with root caries (P&lt;0.05). Adjusted odds ratios demonstrated a 14% increase in the chance of having root caries when the number of teeth increased one unit. Similarly, a 3% increase was observed for each unit increase in the DMF\u2010S scores (p&lt;0.001). Being male, having more than four years of education and earning more than 1500 baht\/month increased the chances of root caries by 76%, 139% and 85% respectively (p&lt;0.001). Recession and age were not statistically significantly associated with root caries.<\/jats:p><jats:p><jats:bold>Conclusions: <\/jats:bold> Having more teeth, higher DMF\u2010S scores, earning more than 1500 baht\/month, having more than 4 years of education and being male increased the likelihood of having root caries.<\/jats:p>","DOI":"10.1111\/j.1741-2358.2000.00091.x","type":"journal-article","created":{"date-parts":[[2004,1,27]],"date-time":"2004-01-27T08:18:22Z","timestamp":1075191502000},"page":"91-96","source":"Crossref","is-referenced-by-count":26,"title":["Number of teeth and risk of root caries"],"prefix":"10.1111","volume":"17","author":[{"given":"Belinda","family":"Nicolau","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patcharawan","family":"Srisilapana","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wagner","family":"Marcenes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,6,28]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0528.1986.tb01491.x"},{"key":"e_1_2_1_3_2","first-page":"219","article-title":"Root caries prevalence in a Norwegian adult dental patient population","volume":"4","author":"Gustavsen F.","year":"1988","journal-title":"Gerodontics"},{"key":"e_1_2_1_4_2","first-page":"111","article-title":"Oral health status in an adult Swedish population.
