Aesthetic management of molar-incisor hypomineralization

Resumo

Molar-incisor hypomineralization (MIH) has been
challenging for clinical practice. The term refers to an enamel defect
that affects permanent molars and often permanent incisors. This
defect may result in high sensibility, coronal destruction of the molars,
aesthetic problem when incisors are affected, which can jeopardize
the child`s emotional and psychological development. Objective: The
aim of this paper is to report two cases in which a conservative
approach was adopted using new technologies for direct restorative
treatment of incisor with MIH opacities. Case report: Patients
aged 11 and 12 years-old attended to the clinics of the School of
Dentistry (Sao Paulo State University – Unesp) complaining about
the appearance of incisors due to the presence of opacities on the
labial surface. The cases were diagnosed as MIH, presenting enamel
defects on the permanent molars and incisors. Direct restorations
were carried out with minimal removal of the opacities using CVD
diamond tip (CVDentus, São José dos Campos, São Paulo, Brazil)
coupled to an ultrasonic device (CVDentus, São José dos Campos, São Paulo, Brazil) and direct restorations with composite resin. The
result of the restorative treatment was satisfactory in both cases, with
children showing immediate satisfaction. Conclusion: The incisors
affected by MIH should be treated to improve the child`s self-esteem
and avoid negative effects on their psychology development. The
aesthetic treatment of the incisors should be conservative, since the
replacements of restorations are needed throughout life.
