Dental caries
Conditions
Interventions
The children will initially be examined for dental caries, MIH and dental biofilm. The exams will be carried out on portable stretcher, with the aid of a clinical mirror, OMS probe and compressed air
Group 2 - Occlusal sealing with high viscosity encapsulated glass ionomer. Those classified as low risk to dental caries will be randomized into: Group 3 - ICON® infiltrant in detected opacity and
Group 4 - No intervention. The procedures will follow the following protocols:
- Application of the ICON® infiltrant in detected opacity:
1) Removal of the dental biofilm with the aid of a toothbrush
2) Topical anesthesia and intraseptal anesthesia, if necessary
3) Absolute insulation with rubber dam for moisture control
4) Application of ICON etch (hydrochloric acid 15%) for 2 minutes, followed by abundant washing
5) Application of ICON dry (alcohol 99%) for 30 seconds, followed by drying with air jets
6) Application of ICON infiltrant for 3 minutes, followed by removal of excess and photoactivation for 40 seconds
7) New application of ICON infiltrant for 1 minute followed by removal of overflows and new photoactivation for 40 seconds.
- Occlusal sealing with high viscosity encapsulated glass ionomer:
1) Condi
2) Washing and drying the surface with cotton ball
3) Activat

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Based on previous studies carried out in a population residing in the same region, it was estimated that the resin infiltration technique is able to reduce in half the loss of dental structure in MIH permanent molars that have white or yellowish-brown demarcated opacities, compared to the control group over a 24-month period | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected that there is correlation between the quality and amount of supragingival biofilm of the teeth evaluated with their protein profile and caries activity | — |
