ClinConnect Summary

This clinical trial is studying how well zirconia crowns work to restore back teeth that have had root canal treatment. Zirconia crowns are strong, tooth-colored caps used to protect and strengthen damaged teeth. The study will compare two different ways of preparing the tooth edges (called finish lines) and two methods of shaping the chewing surface before placing the crown. After the crowns are cemented in place, the researchers will check how well they fit, if there is any discoloration around the edges, if they crack or break, and if new cavities develop, over the course of one year with visits every three months.

People who might join this study are adults between 18 and 65 years old with back teeth that have had root canal treatment. The study does not include front teeth, living (untreated) teeth, people without teeth, or those with serious health problems. If you participate, you can expect to have a crown placed on your treated tooth and then return for follow-up visits every few months to make sure the crown is working well and not causing any issues. This information will help dentists understand the best way to prepare teeth for zirconia crowns to keep them strong and healthy.
