CARIOUS LESION, CAVITY
The children received one of two interventions with an allocation ratio = 1:1. The control group received 38% SDF solution (Advantage Arrest, Elevate Oral Care, FL, USA). Petroleum jelly was applied on the lips and perioral skin as a protective barrier to avoid staining. Gross debris was removed from the carious cavities to allow better SDF contact with denatured dentin. No attempt was made to remove carious tissues before SDF application. The areas to be treated were isolated with cotton rolls and dried with dry cotton pellets. One drop of SDF was carefully applied with a microbrush. Carious lesions were painted for 10 s, and the excess was removed using cotton pellets. The solution was left in contact with the tooth surface for one minute before the child was allowed to close their mouth [The test group received the same 38% SDF solution as the control group and 5% NaF varnish (ALPHA-PRO ® WHITE VARNISH, USA). After the application of SDF using the method described in the control group, it was left to dry for 1 min. Partial isolation of the whole oral cavity was done using cotton rolls. 0.5 ml of 5% NaF varnish was painted over the carious lesion for one minute and on all remaining teeth in the oral cavity for 2–4 min [
