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
