ABSTRACT

Aim

To study the treatment management of first permanent molars in children with Molar-Incisor Hypomineralisation
MIH. Study design Retrospective analysis.

Methods

The records of the clientele of a private paediatric dental practice
were scanned. Thirty-six cases of children fulfilling the diagnostic criteria of MIH were retrieved who had been followed for a mean
period of 4.5 years, and 36 children of matching age and gender, and with similar follow-up period, were randomly selected from the
same clientele to serve as controls.

Results

Children in the MIH group exhibited greater DMFS and smaller dmfs scores. The
frequency of restorative intervention was greater in children of the MIH group OREST=11.00, 95 C.I. 2.85-42.45.
Stainless-steel crowns had been placed only on MIH group molars. The follow-up records revealed that only restorations in the MIH
group needed retreatment. Fillings and sealants in the MIH group had a greater probability of needing retreatment than in the control
group OREST=3.10, 95 C.I. 1.60-6.01. CONCLUSIONS: Children affected by MIH may need to undergo a
significant amount of restorative treatment at an early age. Moreover, fillings and sealants in MIH affected children have a greater
probability of needing retreatment than in control group children.
