Caries lesion initiation/progression (ICDAS score, laser fluorescence/DIAGNOdent, photographic pixels, enamel acid resistance) · Patients (children and adults, age 3-40 years) with initial enamel caries lesions (non-orthodontic and orthodontic)
No meta-analysis was possible for the 5 in vivo RCTs (high heterogeneity); narratively nHA showed generally no significant difference versus fluoridated dentifrice, and the evidence was not graded (ungraded).
