The sample comprised 1,546 preschool\u2010age children (mean age 49 [range: 24\u201371] months) in North Carolina public preschools, enrolled in a population\u2010based investigation among young children and their parents in North Carolina. Information on socio\u2010demographic, extraoral, and intraoral characteristics was collected and analyzed with bivariate and multivariate methods, including logistic regression modeling and marginal effects estimation. The prevalence of dental trauma was 47% and 8% of TDI cases were \u201csevere\u201d (pulp exposure, tooth displacement, discolored or necrotic tooth, or tooth loss). In bivariate analyses, overjet and lip incompetence were significantly associated with TDI. Overjet remained positively associated with severe trauma in multivariate analysis, <jats:italic>OR<\/jats:italic>\u00a0=\u00a01.4, 95% confidence interval (CI) [1.2, 1.6], corresponding to an absolute 1.3%, 95% CI [0.7, 1.8], increase in the likelihood of severe trauma, per millimeter of overjet. Children with increased overjet (&gt;3\u00a0mm) were 3.8, 95% CI [2.0, 7.4], times as likely to have experienced severe TDI compared with those with \u22643\u00a0mm. Overjet is a strong risk factor for TDIs in the primary dentition. Incorporating and operationalizing this information may help TDI prevention and related anticipatory guidance for families of preschool\u2010age children.<\/jats:p>","DOI":"10.1002\/cre2.165","type":"journal-article","created":{"date-parts":[[2019,1,31]],"date-time":"2019-01-31T04:12:00Z","timestamp":1548907920000},"page":"151-159","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Traumatic dental injuries in preschool\u2010age children: Prevalence and risk factors"],"prefix":"10.1002","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8072-250X","authenticated-orcid":false,"given":"Catherine D.","family":"Born","sequence":"first","affiliation":[{"name":"Department of Orthodontics, School of Dentistry University of North Carolina\u2010Chapel Hill  Chapel Hill North Carolina USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tate H.","family":"Jackson","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, School of Dentistry University of North Carolina\u2010Chapel Hill  Chapel Hill North Carolina USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lorne D.","family":"Koroluk","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, School of Dentistry University of North Carolina\u2010Chapel Hill  Chapel Hill North Carolina USA"},{"name":"Department of Pediatric Dentistry, School of Dentistry University of North Carolina\u2010Chapel Hill  Chapel Hill North Carolina USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1290-7251","authenticated-orcid":false,"given":"Kimon","family":"Divaris","sequence":"additional","affiliation":[{"name":"Department of Pediatric Dentistry, School of Dentistry University of North Carolina\u2010Chapel Hill  Chapel Hill North Carolina USA"},{"name":"Department of Epidemiology, Gillings School of Global Public Health University of North Carolina\u2010Chapel Hill  Chapel Hill North Carolina USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,1,30]]},"reference":[{"issue":"6","key":"e_1_2_9_2_1","first-page":"180","article-title":"Guideline on behavior guidance for the pediatric dental patient","volume":"37","author":"American Academy of Pediatric Dentistry Clinical Affairs Committee \u2013 Behavior Management Subcommittee","year":"2015","journal-title":"Reference Manual"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0300-9785(72)80042-5"},{"key":"e_1_2_9_4_1","first-page":"219","article-title":"The effect of traumatic injuries to primary teeth on their permanent successors","volume":"79","author":"Andreasen J.
