Could a crown without drilling beat the drill for Kids' cavities?
NCT ID NCT04367649
First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This trial tests two gentler ways to treat cavities in children's baby molars: the Hall technique, which fits a stainless steel crown without removing decay, and atraumatic restorative treatment (ART), which uses hand tools and adhesive fillings. It compares these to the conventional drilling-and-filling approach in 155 children. The goal is to see which method keeps the teeth healthy and intact over time, while also checking how satisfied the children are with the experience.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Hall technique (stainless steel crown) and atraumatic restorative treatment (ART) compared to conventional fillings
- What this could lead to
- If successful, these less invasive methods could offer children a more comfortable, drill-free way to treat cavities, potentially reducing anxiety and the need for repeat procedures.
- What could go wrong
- The trial is relatively small and early-stage, and results may not apply to all children or cavity types. There is also a risk that the crowns or fillings may fail or cause discomfort.
