ADVERSE EFFECTS, CARIOUS LESION
One group received 38% SDF (Advantage Arrest, Elevate Oral Care, FL, USA) and the other group received 5% NaF varnish (Alpha-Pro® White Varnish, Dental Technologies, USA) combined with 2 MI sessions, at baseline and after three months.At the time of the intervention, teeth were cleaned and partially isolated with gauze and cotton rolls. No attempt was made to remove carious tissues before the application of materials. The isolated lesions were dried with cotton pellets.In the SDF group, petroleum jelly was applied as a protective covering on the lips and perioral skin to avoid staining. One drop of SDF per patient was dispensed into a plastic dappen dish. A disposable microbrush was bent and dipped into SDF and dabbed on the side of the dish to remove excess liquid before applying on the affected tooth. Carious lesions were painted for 10 s and the excess was removed using cotton pellets. The solution was left to dry for one minute before the child was allowed to close their mouth. The application was done once at baseline. In the NaF/ MI group, 0.5 ml of NaF varnish was applied to the whole dentition once at baseline using a disposable brush. The entire process took 3–4 min. After applying the fluoride agents, the children were asked not to eat or drink for 30 min. Oral hygiene instructions were given to all caregivers in the two groups. After 24 h, caregivers were contacted by phone to check if there were any adverse effects.Before providing MI, the principal investigator (RY) completed the online course “Motivational Interviewing -Interventions in Health Care” [The mothers in the NaF/ MI group received 2 MI sessions:10–15 min face-to-face session at baseline and a 5-min phone call after 3 months for reinforcement. Fifteen mothers could not leave their homes to attend the face-to-face session after randomization and received MI over the phone at baseline. A previous study reported no significant differences between face-to-face and phone call MI [
