Interventions
All patients will receive dental prophylaxis with rubber cup and water. A rubber dam will be placed in selected teeth for treatment. Subsequently the patient will be treated according the randomizatio

Eligibility
Age
7 Years to 18 Years
Inclusion criteria
Inclusion criteria: The sample will be composed of children and adolescents, between 7 and 18 years old, with MIH, presenting white-creamy opacities in the enamel of at least one incisor
Exclusion criteria
Exclusion criteria: Patients with other dental developmental defects such as amelogenesis, dentinogenesis imperfecta or fluorosis; Patients with fixed orthodontic appliance; Patients with chronic health syndromes or health impairments that requires special care during dental treatment; Incisors with caries lesions or with demarcated opacities of other origins, such as traumatic sequelae in the predecessor primary teeth
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The evaluation of the impact on the aesthetic perception about the appearance of teeth will be performed through the validated questionnaire "Child's and Parent's Questionnaire about Teeth Appearance" and will be applied to patients and their caregivers before treatment and one month after treatment | — |

| Analysis of the Masking Effect : The result regarding the masking of the opacities will be analysed through the analysis of photographs. Photographs will be obtained from the patient with a digital camera, with macro lens, circular flash, repeating the same exposure, distance and patient's inclination. Photographs will be performed at the beginning of treatment, after insertion of rubber dam, during resin infiltrant application at 3, 10, 15, 20, 25 and 30 minutes of application, after light curing, after rubber dam removal, after polishing and at the follow-up appointment, one month after treatment. To ensure white balance an 18% gray card will be used in all intraoral photographs. ; Quantitative Analysis of the Masking Effect The images saved in JPEG format will be analysed using an Image editor software . The absolute values of luminosity (L), red-green color (a) and yellow-blue color (b) will be analysed in the opacity area and in a sound area according to the International Commission on Illumination of L* a* b* system. The difference values of luminosity (Delta L), red-green (Delta a) and blue-yellow (Delta b) between the opacity and the sound area will be calculated before and after the treatment. Also the total color change will be evaluated through the equation Delta E = (Delta L * ² + Delta a * ² + Delta b * ²) ½. The analyses will be done by a blind examiner in relation to the treatment.;Qualitative Analysis of Masking Opacitiy Effect: The images of the teeth before and after treatment will be organised in a presentation software and presented on the computer to an experienced clinician side by side, on the left the initial image and on the right the final image. In order to evaluate the masking effect qualitatively the examiner will classify the treatment result into: 1) total masking (the opacity is no longer noticeable); 2) Partial masking (opacity coloring close to the sound tooth color and/or reduced in size, but still noticeable); or 3) non-maskin | — |
