Although SDF has been proven to be highly effective in carious lesion arrest and prevention, the staining effect, metallic taste due to silver content and the minimal mucosal irritation have been noted as primary cause of disinterest among clinicians in the use of this material.~The use of NaF-fTCP as a caries preventive material has not been studied widely. The importance of oral hygiene education and diet modification to achieve an effective caries control has been widely discussed. The off-label use of NaF-fTCP as a caries arresting agent has not been studied on primary dentition. There is a dearth of evidence regarding the effectiveness of NaF-fTCP towards caries arrest and prevention in pragmatic settings.~A comparison between the SDF and NaF-fTCP application on the cavitated carious primary molars and their effect on the oral health-related quality of life of the children has not been published in the literature.
There is still a need for the assessment of different minimal intervention strategies and treatments focusing on the prevention and arrest of carious lesions of primary molars The evidence-based clinical practice guideline on non-restorative treatments for cavitated carious lesions advocate the use of silver diammine fluoride biannually for high caries risk patients
