Conclusion
carious lesions, arrest
ARREST
Based on the 6-month results of the current study, there was no significant difference between SDF and NaF/MI in arresting carious lesions. NaF/ MI can be an alternative to SDF to arrest ECC especially moderate lesions (ICDAS 3/4) where the difference between the two regimens was minimal. Studies with longer follow up periods are needed to assess the long-term effects of NaF/MI on ECC arrest.
