title: Relating Molar Incisor Hypomineralization and Caries Experience Using the Decayed, Missing, or Filled Index.
abstract: OBJECTIVE
  This case-control study aimed to investigate the association between molar incisor hypomineralization (MIH) and caries experience in seven- to 11-year-old children.
  
  
  METHODS
  Children seen in a pediatric dental clinic in 2011 to 2012 and born in 2002, 2003, or 2004 were considered eligible. Children with decayed, missing, or filled teeth in the permanent dentition (DMF-T) were allocated to the case group, and those with no DMF-T were allocated to the control group. An examiner assessed MIH according to European Academy of Pediatric Dentistry criteria and caries according to World Health Organization criteria. The odds ratio was calculated to evaluate the association between MIH and caries; the chi-square test was used to analyze the association between categorical variables, and the Mann-Whitney test was used to compare means.
  
  
  RESULTS
  The final sample comprised 57 children in the case group and 98 in the control group. The groups were similar in relation to age, gender, and caries experience in the primary dentition. MIH children were 5.89 (95 percent confidence interval equals 2.69 to 12.86; P<0.05) times more likely to have a DMF-T greater than zero.
  
  
  CONCLUSIONS
  Children with decayed, missing, or filled permanent teeth are more likely to have MIH.
