Outcome Measures

Primary Outcomes (1)

  • Increase in caries incidence

    Caries increment in primary molar teeth, primary canines and erupted occlusal surfaces at the first permanent molar teeth in children aged 5-8 years, using a modified dmf-s scale, including the occlusal surfaces of the first permanent teeth where d is defined by ICDAS scale and assessed both clinically and by dental x-ray.

    12 months
