title: Association between unmet dental needs and school absenteeism because of illness or injury among U.S. school children and adolescents aged 6-17 years, 2011-2012.
abstract: BACKGROUND
  We assessed the prevalence of dental disease among U.S. children and adolescents aged 6-17 years, as well as the impact of unmet dental needs on school absenteeism because of illness/injury within the past 12 months.
  
  
  METHODS
  Data were from the 2011/2012 National Survey of Children's Health (n=65,680). Unmet dental need was defined as lack of access to appropriate and timely preventive or therapeutic dental healthcare when needed within the past 12 months. The impact of unmet dental needs on school absenteeism was measured using a multivariate generalized linear model with Poisson probability distribution (p<0.05).
  
  
  RESULTS
  Within the past 12 months, 21.8% (10.8 million) of all U.S. children and adolescents aged 6-17 years had "a toothache, decayed teeth, or unfilled cavities." Of all U.S. children and adolescents aged 6-17 years, 15.8% (7.8 million) reported any unmet dental need (i.e., preventive and/or therapeutic dental need) within the past 12 months. The mean number of days of school absence because of illness/injury was higher among students with an unmet therapeutic dental need in the presence of a dental condition compared to those reporting no unmet dental need (β=0.25; p<0.001).
  
  
  CONCLUSIONS
  Enhanced and sustained efforts are needed to increase access to dental services among underserved U.S. children and adolescents.
