简要总结
This study aims to evaluate the effectiveness of 30% silver diamine fluoride in the treatment of clinically caries lesions in enamel, with radiographic image restricted to the enamel or the outer third of dentin on the proximal surfaces of primary and permanent posterior teeth. It also aims to compare it to the resin infiltration and to the control of proximal biofilm through the oral hygiene.
详细描述
The sample will be comprised of 141 patients between 3 to 10 year-old and 504 proximal surfaces of 12-to-17-year-old adolescents, who present at least one proximal surface with initial caries lesion. Patients will be randomly allocated to treatments, according to the technique to be employed: (I) resin infiltration (II) 30% diamine silver fluoride, (III) just daily flossing by the patient. All subjects will receive placebo treatments performed in other groups. The teeth will be evaluated by clinical and radiographic exams at baseline and after 1, 3, 6, 12, 18 and 24 months. In 1, 3 and 18 months will just be evaluated aspects related to the biofilm.

入选标准
- •Primary teeth: distal surface of the first molar, mesial surface of the second molar and distal surface of the second molar (when the first permanent molar is present) with initial caries lesion (ICDAS 1, 2 or 3).
- •Permanent teeth: distal surface of the first premolar, mesial surface of the second premolar, distal surface of the second premolar, mesial surface of the first molar, distal surface of the first molar and mesial surface of the second molar with initial caries lesion (ICDAS 1, 2 or 3).
排除标准
- •Mesial surface of the first primary molar/premolar by the smaller contact with the distal surface of the canines. It will be also excluded the surfaces that show proximal restorations, sealants, cavities, defects, as well as intact teeth.
