Prevalence, Etiology and Effects on Oral Health and Life Quality of Molar Incisor Hypomineralization

Study Overview
=================
Brief Summary
-----------------
Molar incisor hypomineralization (MIH) can lead to many clinical conditions and affect oral health-related quality of life (OHRQoL).

Detailed Description
-----------------
Molar incisor hypomineralization (MIH) can lead to many clinical conditions and affect oral health-related quality of life (OHRQoL). The aim of this study was to determine the prevalence, etiology and impacts of MIH on oral health status and OHRQoL. Six hundred and fifty-five parents and their children aged 9 years were included in the study. After parents completed the questionnaire about the etiology of MIH, children's OHRQoL was measured by the Child Perceptions Questionnaire (CPQ8-10). Children were evaluated for presence and severity of MIH, dental caries experience and oral hygiene status. Qualitative data were analyzed with the Pearson chi-square and Fisher's exact tests. For the quantitative data, if the normal distribution was not satisfied, Kruskal Wallis/Mann-Whitney U tests were used. Also, Binominal logistic regression analysis was performed and p<0.05 was statistical significant. .

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To determine the prevalence and etiology of MIH. | A questionnaire was applied to the parents about the etiological factors and the prevalence of MIH was determined by oral examination. | up to four months | 
| To evaluate the impacts of MIH on oral health status. | Oral health was evaluated by recording dmft (decayed, missing and filled teeth) and plaque index values. | up to six months | 
| To evaluate the impacts of MIH on OHRQoL. | The impact of MIH on quality of life (OHRQoL) was measured with the Child Perception Questionnaire (CPQ8-10). | up to six months |
