Prevalence of molar incisor hypomineralisation and associated factors amongst 8-year-olds in Ireland.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo describe the prevalence of molar incisor hypomineralisation (MIH) and a selection of potentially associated factors amongst 8-year-olds in Ireland.
methodsThis study reports cross-sectional data from the Fluoride and Caring for Children's Teeth (FACCT) study 2017. Eight-year-olds in Dublin (n = 786) and Cork-Kerry (n = 1524) were clinically examined for MIH (EAPD criteria) and dental caries (DMFT). The association between potential aetiological factors and MIH was assessed using multivariable logistic regression. Potential effects of MIH on dental caries, oral health-related quality of life (OHRQoL) and parental perceptions of the appearance of their child's permanent incisors were investigated.
resultsMIH prevalence was 11% in Dublin and 9% in Cork-Kerry. In Dublin, prevalence of MIH was higher amongst children who had health problems in the past year. There was no association between community water fluoridation and MIH in Cork-Kerry. In both regions, dental caries was higher amongst children with MIH. Parents of children with MIH in Dublin and Cork-Kerry were more likely to have noticed marks on their child's permanent incisors. In Dublin, MIH was associated with poorer parent-reported OHRQoL. Parents of children with MIH in Cork-Kerry were less likely to be satisfied with the colour of their child's permanent incisors.
conclusionsMIH prevalence was 9-11%. The association between MIH and dental caries suggests that MIH severity in Ireland may be high. There is an urgent need for national data on MIH prevalence and severity, early identification of children with MIH and provision of preventive and treatment services in line with international best practise.
