Objective: To estimate the prevalence and describe the distribution of demarcated opacities and possible consequences of this condition in permanent 1st molars and incisors in Danish children.
Material And Methods: Among all 6 to 8-year-old children in two municipalities, 745 (83.6%) were clinically examined for the occurrence of creamy-white or yellowish-brown demarcated opacities, posteruptive breakdown of tooth substance in relation to the opacities, atypical restorations, and extractions, i.e. restorations or extractions as a result of the occurrence of demarcated opacities.
Results: In 647 children with four fully erupted permanent 1st molars, the prevalence of demarcated opacities and of lesions with loss of tooth substance due to demarcated opacities in any 1st molar was 37.3% (95% confidence interval (95% CI) 33.6-41.0%) and 6.3% (95% CI 4.7-8.5%), respectively. Permanent incisors were 2.5 times more frequently affected among children with one or more affected permanent 1st molar than among children with no such teeth. Demarcated creamy-white opacities were the type of lesion found most frequently, and the most frequently affected tooth types were the upper central incisors followed by 1st molars.
Conclusions: Nearly half of the examined 6 to 8-year-old children had permanent 1st molars or incisors with demarcated opacities. More than 6% of the children had macroscopic loss of tooth substance due to demarcated opacities.

Molar Incisor Hypomineralisation: A Recent Condition or a New Perception?

The condition known as molar incisor hypomineralisation (MIH) has been featured in the dental literature for some time. However, the condition itself, characterized by demarcated opacities, had been observed and documented in various forms before the official terminology was coined. The awareness and understanding of MIH have increased over the years, and there has been ongoing research to explore its prevalence, etiology, clinical implications, care, and treatment.

This review aims to present scientific knowledge regarding the demarcated opacities of molar incisor hypomineralisation (MIH) and factors that clarify the occurrence of posteruptive enamel breakdown. The demarcated opacities have distinct boundaries with the adjacent nonaffected enamel and may vary in color among white, creamy, yellow, and brownish. The hypomineralised enamel is more porous and less organized than the nonaffected enamel.

Hypomineralisation defects with demarcated opacities are also observed in the deciduous dentition and have been found to be a predictive factor for hypomineralisation defects in the permanent dentition. Deciduous molar hypomineralisation (DMH) represents a qualitative enamel defect primarily afflicting deciduous second molars, albeit its presence is not limited solely to deciduous second molars, as it can manifest in deciduous canines and first molars. Thus, the presence of demarcated hypomineralisation defects in deciduous teeth could be called as deciduous teeth hypomineralisation.

Background/aim: Alveolar bone process fractures in preschool children are not well documented in the literature. Alveolar process fractures are located very close to primary teeth and permanent tooth germs. This study investigates the risk of healing complications following alveolar process fractures in the primary dentition and potential sequelae in the permanent dentition.

Introduction: Molar-incisor hypomineralization (MIH) is a localized, qualitative, demarcated enamel defect that affects first permanent molars (FPMs) and/or permanent incisors. The aim of present study was to introduce a novel computerised assessment process to detect and quantify the percentage opacity associated with MIH affected maxillary central incisors.
Methodology: Children (8-16 years) enrolled in the primary study having mild (white/cream or yellow/brown) MIH lesion on fully erupted maxillary permanent central incisor.
