About this study
Official title: General Dentists' Knowledge, Attitudes and Utilisation of Silver Diamine Fluoride for Caries Management in Children: A Multi-Region Survey
This study will look at how dentists in the UK are using Silver Diamine Fluoride (SDF) in their everyday practice. SDF is a liquid treatment that helps stop tooth decay. It's especially useful for treating children, as it can be applied quickly and without the need for drilling or needles. However, it seems that not many dentists are using SDF regularly, and this research aims to find out why.
The study will use an anonymous online survey to ask dentists about:
Read more
- How much they know about SDF and its benefits.
- Whether they use SDF in their practice and how they use it.
- What might stop them from using SDF, such as lack of training, cost, or concerns about how patients might feel about it.
The answers will be analysed to see what's working well and what's not when it comes to SDF use. The goal is to help dentists better understand and use this treatment, making it easier to manage tooth decay in children and improve their overall oral health.

Clinical summary

This study will look at how dentists in the UK are using Silver Diamine Fluoride (SDF) in their everyday practice. SDF is a liquid treatment that helps stop tooth decay. It's especially useful for treating children, as it can be applied quickly and without the need for drilling or needles. However, it seems that not many dentists are using SDF regularly, and this research aims to find out why.
