Outcome of Selective Caries Removal Performed by Undergraduate Students

Sponsor: King Abdullah University Hospital

Summary

Deep tooth decay can sometimes reach very close to the nerve of a tooth. Traditionally, dentists may remove all of the decayed tooth tissue, but removing too much tissue can increase the risk of exposing or damaging the nerve. This study is looking at a more conservative way of treating deep tooth decay called selective removal of tooth decay. Instead of removing all the affected tissue close to the nerve, some of it is carefully left in place to help protect the nerve and preserve the tooth. We will compare two ways of doing this. In one group, the dentist will remove the decay until softer tooth tissue remains near the nerve. In the other group, the dentist will remove more of the decay until firmer, leathery tooth tissue remains. About 100 patients with deep tooth decay in permanent teeth will take part in the study. The treatment will be provided by trained fifth-year dental students under supervision and using standardized procedures. After treatment, patients will be asked about any pain at 1, 3, and 7 days. The treated teeth will also be checked clinically and with dental X-rays at 6 and 12 months. The purpose of the study is to find out whether either approach provides better outcomes while preserving the health of the tooth. The results may help dentists choose the most appropriate and conservative way to treat deep tooth decay and may also help improve dental student training.
