Clinical Trial Summary

Early childhood caries (ECC) is the most common chronic childhood disease worldwide. Early restorative intervention may treat the disease but this is often difficult especially with uncooperative children so it may be left untreated. Remineralization of affected dentin using silver diamine fluoride (SDF) can arrest these lesions.

This trial aims to compare the effectiveness of 38% SDF solution versus 38% SDF solution with 5% sodium fluoride (NaF) varnish after six months in arresting ECC lesions.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The percentage of arrested carious lesions	For cavitated dentine caries lesions diagnosed as ICDAS code 5 or 6, visual inspection and tactile detection using a 0.5mm ball-ended Community Periodontal Index (CPI) probe without radiograph examination will be used for assessing caries activity according to Lesion Activity criteria of ICDAS II. If a wall or floor of the lesion is soft and easily penetrated by the probe using light force, then it will be diagnosed as active. A lesion with all surfaces being hard and smooth will be diagnosed as arrested caries .For a moderate caries lesion with no visible dentine (ICDAS code 3 or 4) at baseline, it will be classified as arrested caries at follow-up examination if the lesion did not progress to become a cavitated lesion with visible dentine (ICDAS code 5 or 6). Five tooth surfaces (buccal, lingual, mesial, distal and occlusal) will be examined in each posterior tooth and 4 tooth surfaces (labial, lingual, mesial and distal) in each anterior tooth.	6 months
Secondary	Caries Increment (number of new caries lesions)	New caries lesions will be assessed through visual and tactile inspection using the World Health Organization (WHO) criteria for caries diagnosis. Full mouth examination will be conducted with the aid of a WHO CPI probe, and a disposable dental mirror. Five tooth surfaces (buccal, lingual, mesial, distal and occlusal) will be examined in each posterior tooth and 4 tooth surfaces (labial, lingual, mesial and distal) in each anterior tooth to assess the caries increment using the decayed, missing (due to caries), and filled primary tooth index per surface (dmfs).	6 months
Secondary	Parental satisfaction with SDF application	Parents will be asked If SDF Application is an easy process. Answers will be on a 5 point Likert scale (Strongly agree, Agree Neutral , Disagree, Strongly disagree).	Baseline and at 6 months
Secondary	Parental satisfaction with SDF application	Parents will be asked if they are comfortable with discoloration of cavities after SDF placement, Answers will be on a 5 point Likert scale (Strongly agree, Agree Neutral , Disagree, Strongly disagree).	Baseline and at 6 months
Secondary	Parental satisfaction with SDF application	Parents will be asked If SDF application was pain free for their child .Answers will be on a 5 point Likert scale (Strongly agree, Agree Neutral , Disagree, Strongly disagree).	Baseline and at 6 months
Secondary	Parental satisfaction with SDF application	Parents will be asked if The taste of SDF was acceptable to their child.Answers will be on a 5 point Likert scale (Strongly agree, Agree Neutral , Disagree, Strongly disagree).	Baseline and at 6 months
Secondary	Adverse effects reported after application of the interventions	Parents will be asked if their child experienced tooth or gum pain after application of the material.; (Yes/No) Question	Baseline and at 6 months
Secondary	Adverse effects reported after application of the interventions	The clinician will observe if gum swelling occurred after application of the material.; (Yes/No) Question	Baseline and at 6 months
Secondary	Adverse effects reported after application of the interventions	The clinician will observe if gum bleaching occurred after application of the material.; (Yes/No) Question	Baseline and at 6 months
Secondary	Adverse effects reported after application of the interventions	Systemic toxicity (nausea, vomiting, generalised discomfort) will be assesses by the clinician at the time of application and by asking the parents one week later.; (Yes/No) Question	Baseline and at 6 months
Secondary	Adverse effects reported after application of the interventions	Black staining of each lesion will be clinically observed and recorded (yes/no).	Baseline and at 6 months
