Official Title: Evaluation of Three Different Approaches Using Prolonged Resin Infiltration on Demarcated Enamel Opacities in Incisors Affected With Molar Incisor Hypomineralization: A Randomized Clinical Trial
Brief Summary: Molar incisor hypomineralization (MIH) is a condition which involves enamel hypomineralization of one to four first permanent molars with or without permanent incisors. Affected permanent incisors present with demarcated enamel opacities which cause esthetic and psychological problems to patients with MIH. Microabrasion and etch-bleach surface treatment can provide easier, conservative, and biologically driven treatment approach compared to macroabrasion prior to prolonged resin infiltration for treating enamel opacities in incisors of MIH patients.

The aim of this study is to evaluate the effect of microabrasion and etch-bleach surface treatment compared to macroabrasion prior to prolonged resin infiltration on esthetic appearance of permanent incisors affected with demarcated enamel opacities in MIH patients.

Participation Criteria

Ages Eligible for Study: Child (0-17)
Sexes Eligible for Study: All
Accepts Healthy Volunteers?: Yes
Eligibility Criteria: Inclusion Criteria:

Cooperative healthy male and female children aged 8 to 14 years.

MIH diagnosed patients according to the criteria of European Academy of Pediatric Dentistry (EAPD) with demarcated enamel opacity that caused esthetic discomfort to them and their guardian, involving at least one maxillary or mandibular permanent incisor.

At least one-third of the affected tooth crown should be visible in the oral cavity.

Exclusion Criteria:

Children with behavioral, cognitive, physical, or medical conditions that will affect or complicate the treatment.

Other developmental defects of dental enamel rather than MIH (i.e. dental fluorosis, enamel hypoplasia, amelogenesis imperfecta or Turner's tooth)

Loss of tooth structure due to post-eruptive enamel breakdown or caries.

Periodontal disease of the affected tooth.

Incisors previously subjected to trauma that might lead to loss of tooth structure or compromise the pulp vitality.

Previous preventive, restorative or orthodontic treatment on the affected tooth.
