Transform a Tooth with a Transformer Tooth: a randomised control trial of the Hall Technique compared with conventional restorative care in 3-7-year-old children in the New Zealand Community Oral Health Service with primary outcome of clinical and radiographic success

None listed

Tooth decay is a really common problem. For years decayed teeth have been fixed by drilling out the decay and then placing fillings. We know that in children’s teeth, fillings don’t last for as long as they do in adults, and that this often means fillings are done again and again in the same tooth. The Hall Technique is a new way of treating decayed children’s primary molar (back) teeth. In the Hall Technique, a stainless steel crown (SSC) is glued on over the decayed tooth without injections or drilling. This seals in the decay and stops it from getting worse, and the stainless steel crown lasts for longer than any other type of filling, so retreatment is less likely to be needed. This study will measure the success of Hall Technique compared to the treatment usually given (mostly fillings) for children who attend the Whanganui District Health Board Community Oral Health Service dental clinics.
