Impact of molar incisor hypomineralization on oral health-related quality of life in 8-10-year-old children.

Abstract

OBJECTIVES\nThe aim of this study was to compare oral health-related quality of life (OHRQoL) in children with and without molar incisor hypomineralization (MIH) and to assess the impact of severity of MIH on OHRQoL in children between 8-10\xa0years using the German version of the Child Perceptions Questionnaire (CPQ-G8-10).\n\n\nMATERIALS AND METHODS\nChildren aged 8-10\xa0years were recruited at a pediatric dental clinic in Hannover, Germany. Half of them were affected by MIH. Participants were evaluated for presence and severity of MIH (MIH-TNI), plaque and dental caries status. Children were asked to answer the CPQ-G8-10. Statistical analysis was performed using GraphPad Prism-software version 8.\n\n\nRESULTS\nOne hundred eighty-eight children (mean age 8.80 [±\u20090.84]; 43.10% female) were included in the study with 94 children having MIH. CPQ-G8-10 mean scores in MIH-affected children were significantly higher than in children showing no MIH (13.87 [±\u20098.91] vs. 4.20 [±\u20093.74]; p\u2009<\u20090.0001) showing that MIH has negative impact OHRQoL. Similar trends were seen in all four subdomains. Regarding severity, CPQ-G8-10 mean scores increased from mild to severe forms of MIH.\n\n\nCONCLUSION\nChildren affected by MIH show an impaired OHRQoL compared to children without MIH; with increasing severity, OHRQoL gets more impaired. Clinical relevance To understand the patient s perception and the individual oral health needs will help to prioritize MIH and recognize its impact.
