Summary

This study looks at how placing a special type of crown (Hall crown) on decayed baby molars changes the way children's teeth fit together. Researchers will measure tooth movements and bite contact areas in 60 children over one month using digital scans. The goal is to understand these changes better, not to test a new treatment.
