Abstract
ObjectivesThis study was aimed to compare the impact of caries and molar incisor hypomineralization (MIH) on oral health-related quality of life (OHRQoL) in children.Material and methodsA total of 528 German children aged 7 to 10 years were recruited, half affected by caries and the other half affected by MIH. Both groups were matched according to age, sex, and social status and divided into 3 categories according to severity. The German version of the Child Perceptions Questionnaire for 8- to 10 years old (CPQ-G8-10) was used to analyze the impact on OHRQoL by applying ANOVA models.ResultsPatients with MIH showed a mean CPQ score of 10.7 (± 9.3). This was significantly higher compared to the caries group with 8.1 (± 9.8). The score increased linearly from the low severity category to the high severity category in both groups (caries, 4.1 to 13.8; MIH, 5.2 to 17.7, respectively).ConclusionWith increasing severity, both clinical conditions showed a greater negative impact on OHRQoL. MIH was associated with more impairments.Clinical relevanceCurrently, the focus in pediatric dentistry is placed on the prevention and treatment of caries. Both diseases may have a negative influence on OHRQoL. Since children perceive the impairments by MIH as worse and the prevalence is equal to that of caries, which focus might be shifted in the future.
Highlights
Over the past few decades, there has been a major decrease in the prevalence of caries in children and teenagers in WesternHypomineralized teeth, which clinically resemble teeth affected by molar incisor hypomineralization (MIH), were first described in 1987 [5]
Almost half (49%) of the participants were from the middle class, while 28% were from the lower social class, and 23% were from the higher social class, according to Winkler and Stolzenberg’s [22] classification
This study shows that both diseases, caries, and MIH have a severe influence on the oral health-related quality of life (OHRQoL) of children in this age group
Summary
Over the past few decades, there has been a major decrease in the prevalence of caries in children and teenagers in WesternHypomineralized teeth, which clinically resemble teeth affected by molar incisor hypomineralization (MIH), were first described in 1987 [5]. Over the past few decades, there has been a major decrease in the prevalence of caries in children and teenagers in Western. According to the 2016 Fifth German Oral Health Study, the prevalence of MIH among 12 years old peaked at around 30%, which was higher than the prevalence of caries seen in children of the same age group [1]. Chronic pain can cause difficulties in concentration and, could negatively impact children’s capabilities in school [14]. Both diseases can cause esthetic issues, which might influence the emotional state of the child. The Child Perceptions Questionnaire (CPQ8-10, CPQ11-14) is frequently used [15, 16]
