Effectiveness of Single and Dual Silver Fluoride Application
The Effectiveness of Single and Dual Silver Fluoride (SF) Applications on Dentine Caries Among Malaysian Preschool Children: A Randomised Controlled Trial
This is a community-based, parallel-group, double-blinded randomised controlled trial aimed at evaluating the effectiveness of single and dual applications of 38% Silver Fluoride (SF) in arresting dentinal caries among Malaysian preschool children aged 4 to 6 years.
The main questions this study aims to answer are:
i) Does dual application of 38% Silver Fluoride differ from single application in arresting dentinal caries lesions after 6 months? ii) How does SF application influence oral health-related quality of life (OHRQoL) among preschool children, as measured by the Malay-ECOHIS questionnaire? iii) Is there a correlation between caries arrest and changes in Oral Health-Related Quality of Life (OHRQoL) measured using the Malay-ECOHIS questionnaire?
Researchers will compare children receiving a single application of 38% Silver Fluoride with those receiving dual applications to determine whether more frequent application improves caries arrest outcomes.
Participants will:
i) Undergo oral examination for assessment of dentinal caries using ICDAS criteria.
ii) Receive 38% Silver Fluoride application at baseline, with the dual-application group receiving an additional application at 3 months.
iii) Attend follow-up assessments at 3 and 6 months to evaluate caries arrest status.
iv) Have parents or guardians complete the Malay-ECOHIS questionnaire to assess changes in OHRQoL.

Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Comparatore placebo: Single Application of Silver Fluoride
Single applications of 38% silver fluoride will be applied to dentinal carious lesions at baseline and followed by placebo (normal saline) at 3 months
|
Topical application of 38% silver fluoride will be apply onto dentinal caries lesions using a micro-brush at baseline and 3 months follow up.
One drop (0.05 mL) treats up to five surfaces.
Maximum dose per visit does not exceed 260 µL.

|
|
Sperimentale: Dual Application of Silver Fluoride
Two applications of 38% silver fluoride will be applied to dentinal carious lesions at baseline and 3 months.
|
Topical application of 38% silver fluoride will be apply onto dentinal caries lesions using a micro-brush at baseline and 3 months follow up.

Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Caries arrest at tooth surface level
Lasso di tempo: 6 months
|
Lesions are considered arrested if they are hard upon probing using WHO probe and have turned black in colour.
Each tooth may contribute up to five surfaces, with analysis conducted at the lesion level.
|
6 months
|
|
Proportion of arrested lesions
Lasso di tempo: 6 months
|
Caries arrest will be assessed at the tooth surface level.
The outcome is defined as the proportion of lesions classified as arrested out of the total treated lesions in each group.
Comparisons will be made between single and dual application groups.
Analyses will be conducted at both surface (lesion) level and participant level, accounting for clustering of lesions within individuals.

Misure di risultato secondarie

Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Change in OHRQoL (Malay-ECOHIS score)
Lasso di tempo: Baseline to 6 months
|
Change in total Malay-ECOHIS score from baseline to 6 months will be assessed.
The Malay-ECOHIS is a validated parent-reported questionnaire measuring the impact of oral health on children and their families.
Scores range from 0 to 52, with higher scores indicating worse oral health-related quality of life.
A reduction in score reflects improvement in OHRQoL.
|
Baseline to 6 months
|
|
To determine correlation between caries arrest rate and change in total Malay-ECOHIS score
Lasso di tempo: 0-6 months
|
This outcome will assess the correlation between caries arrest rate at 6 months and change in total Malay-ECOHIS score from baseline to 6 months. Caries arrest rate (%) will be assessed by clinical examination and calculated as the number of arrested treated dentinal caries lesions divided by the total number of treated dentinal caries lesions per participant, multiplied by 100. The unit of measure is percentage (%) of arrested treated dentinal caries lesions. Change in total Malay-ECOHIS score will be assessed using the Malay-ECOHIS questionnaire. The change score will be calculated as the total score at 6 months minus the baseline total score. The unit of measure is change in total Malay-ECOHIS score. Pearson correlation will be used if normality assumptions are met; otherwise, Spearman rank correlation will be used. |
