Summary

This study compares two methods of hardening a tooth-colored filling material in children's baby molars. One method uses a fast 5-second light, the other a standard longer light. Researchers want to see if the fast method works just as well and is as safe over 12 months. About 70 children with cavities in two different baby molars will take part.
