ClinConnect Summary

This clinical trial is studying the effectiveness of a teeth whitening treatment using a product called 16% carbamide peroxide, which is known to brighten teeth but can sometimes cause sensitivity. The trial aims to find out if using this whitening treatment every day for two hours is different from using it every other day in terms of how much dental sensitivity patients experience. Participants will be monitored over three weeks to see how their teeth react to the whitening process.

To participate in this study, individuals must be at least 18 years old and have healthy teeth that meet specific criteria, meaning no cavities or restorations and good oral hygiene. They also need to have teeth that are a certain shade of darkness to qualify. If you decide to join, you can expect to use the whitening trays for a set amount of time while being observed for any changes in sensitivity. It's important to note that certain individuals, such as those with specific dental issues or medical conditions, may not be eligible to participate to ensure everyone's safety during the trial.
