This CASE-CONTROL study aimed to evaluate the association between Molar incisor hypomineralization (MIH) and the need of operatory treatment in permanent teeth. Dental anxiety and the impact of oral conditions on the quality of life were also assessed. CASE and CONTROL groups were selected from the list of patients assisted at the Pediatric Dental Clinic of the State University of Rio de Janeiro, Brazil in 2011 and 2012 who were born in 2002, 2003 and 2004. CASES were those who needed operatory treatment in at least one permanent tooth and CONTROLS were those who did not need any operatory treatment in permanent teeth. One single calibrated examiner performed all the examinations. Enamel hypomineralization and caries were assessed at the tooth surface level. Caries risk was assessed using Cariogram. The facial images scale was used to assess dental anxiety before and after the dental appointment. The Child s Perception Questionnaire (CPQ8-10) assessed the impact of oral conditions on the quality of life. The sample comprised 155 patients, aged 7 to 11 years, 57 CASES and 98 CONTROLS. Among CASES, 47.4% of the children had MIH, and among CONTROLS, MIH was present in 13.3% of the children. The chance of needing operatory treatment in permanent teeth was 5.89 (CI: 2.69-12.86) times higher in patients with MIH. The mean number of first permanent molars and the mean number of tooth surfaces of first permanent molars, which needed operatory intervention, were significantly higher among children with MIH (p<0.05; p<0.01). Dental anxiety after the dental appointment was higher in the CASE group (p=0.04). Although the Global CPQ8-10 scores and the scores of the subscale Emotional well-being were slightly higher in the CASE group, the difference was not statistically significant (p>0.05). Functional limitations scores were slightly higher in the CASE group when MIH was present, but not statistically significant (p=0.05). Based on the data of the present study it can be concluded that: MIH increased the need of operatory intervention in permanent teeth significantly; dental anxiety after the dental appointment was higher among those who needed operatory treatment in permanent teeth; child s perception about the impact of oral conditions on the quality of life was not different between those who needed and did not need operatory intervention in permanent teeth.
