Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To compare the effectiveness of the semi-annual application of 38% SDF with two post-treatment protocols in arresting dental caries in preschool children

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Methods: The randomized clinical trial will recruit 254 healthy kindergarten children aged 3-4 years old with caries and with parental consent. All the tooth surfaces with carious lesions will receive the semi-annual application of 38% SDF solution. After the treatment, children will be allocated to two groups by an independent research assistant. Two post-treatment protocols are as follows.

Group A - Children are instructed to rinse their teeth with a cup of water containing about 50 ml immediately after SDF treatment. Afterwards, no post-treatment protocol is given to children.

Group B - Children are instructed not to eat and drink for at least 30 minutes. Clinical examinations after 6-months will be conducted to assess whether the caries is arrested. Information on confounding factors, such as oral hygiene habits and the use of other fluoride agents, will be collected through a parental questionnaire at the baseline and 12-months follow-up. The analysis will determine the significance of differences between the percentage of arrested caries at the various follow-ups.

Significance: This study will help determine the optimal post-op treatment in SDF treatment. The study provides an evidence-based protocol for the use of silver diamine fluoride to arrest tooth decay in primary teeth of young children.
