Abstract
ObjectivesThe 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 years using the German version of the Child Perceptions Questionnaire (CPQ-G8-10).Materials and methodsChildren aged 8–10 years 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.ResultsOne hundred eighty-eight children (mean age 8.80 [± 0.84]; 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 [± 8.91] vs. 4.20 [± 3.74]; p < 0.0001) 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.ConclusionChildren affected by MIH show an impaired OHRQoL compared to children without MIH; with increasing severity, OHRQoL gets more impaired.Clinical relevanceTo understand the patient’s perception and the individual oral health needs will help to prioritize MIH and recognize its impact.
Highlights
Molar incisor hypomineralization (MIH) is a phenomenon defined as a quality defect of enamel of systemic origin of one to four permanent first molars frequently associated with affected incisors [1]
A significant higher Approximal Plaque Index (API) was observed in children suffering from MIH (50.53% (± 33.72) vs. 40.34% (± 33.07)) (p < 0.05, Mann–Whitney test)
This study compared oral health–related quality of life (OHRQoL) in German children with and without MIH presenting in a private pediatric dental practice and assessed the impact of severity of MIH
Summary
Molar incisor hypomineralization (MIH) is a phenomenon defined as a quality defect of enamel of systemic origin of one to four permanent first molars frequently associated with affected incisors [1]. It affects around 13.1% of the global population that is around 878 million people. The children’s appearance upsets the mothers and has a negative influence on the children, preventing them from smiling [8] Such aesthetics may lead to a negative social impact [7]
