CARIES
As described above, the children were randomly divided into three different groups according to the mode of treatment:NaF varnish group (NaFV) APF in tray group (APFt) APF in toothbrush group (APFtbru) Three-row children’s brushes with soft, rounded nylon bristles, a compact head and a straight handle were used for all groups.Enrolment in each group was performed by balancing the CNTI13 categories in each group.A protocol was applied to all children, based on dental care programs to be carried out in school and dental clinics, with the aim of controlling caries lesions. All the children received teaching and control of personal oral hygiene, dietary counselling, and calculus removal. Caries lesions treatment was divided according to ICDAS code, extension, and severity of the lesions and also according to the dentition. For initial (1–2) inactive caries, active monitoring was done. For initial (1–2) active caries, the care option for primary dentition was silver diamine fluoride (SDF) 38% and for permanent dentition 5% fluoride varnish. For enamel (3) inactive caries, SDF for primary and fluoride varnish for permanent. For m (3) active caries, SDF for primary and permanent molar teeth. For extensive (4–5–6) caries, SDF or atraumatic restorative treatment (ART) were the selected care options for primary teeth according to the extension; meanwhile, for permanent teeth, ART was chosen.
