Management of a Hypomineralisation of the Enamel by Applying a Remineraliser Based on Zinc Hydroxyapatite (microRepair)

Table 1

Features for the diagnosis of MIH.

Key features	Description
Bounded opacity	(i) Delimited opacity; (ii) Variability of colour and size; (iii) Defects of less than 1 mm
Loss of posteructive enamel	(i) Surface defect after tooth eruption; (ii) Loss of enamel from a surface initially formed after tooth eruption; (iii) Frequently associated with a preexisting demarcated opacity
Atypical restorations	(i) Size and shape of restorations not in accordance with carious images; (ii) Frequent extensions to buccal and palatal/lingual surfaces; (iii) Frequently associated with opacity at the margin of the restoration; (iv) For the incisors, buccal restoration not related to trauma can be seen
Molar extraction due to MIH	(i) The absence of a permanent first molar should be related to the other teeth; (ii) Opacities and atypical restorations in other permanent first molars combined with the lack of a permanent first molar; (iii) Absence of the first permanent molars in an otherwise healthy dentition in combination with demarcated opacities on the incisors
Failure of a molar or incisor to erupt	(i) The permanent first molar or incisor to be examined has not yet been erupted
