PLAQUE
The inclusion criteria were children ≤ 4 years old with at least one active carious lesion on a primary tooth with ICDAS score of 3 to 6. The activity of the lesion was assessed using the ICDAS-LAA criteria where ICDAS 3 lesions were active if the enamel surface was opaque with loss of luster and present in plaque stagnation areas as pits and fissures, near gingival margin or in proximal surfaces below contact point. ICDAS 4 lesions were all considered probably active. ICDAS 5 or 6 lesions were identified as active if softness was detected on gentle probing [
