ClinConnect Summary

This clinical trial is studying two methods of treating deep tooth decay in permanent teeth, called non-selective caries removal (NSCR) and selective caries removal (SCR). Both methods are commonly used by dentists but we want to see which one works better in keeping teeth healthy over time. Participants in the study will be divided into two groups: one will receive NSCR, and the other will have SCR. If a tooth has a problem with its inner pulp, both groups will also receive a treatment called Partial Pulpotomy. The success of these treatments will be checked at follow-up visits over 1, 3, and 5 years using X-rays to see how well the tooth is doing.

To be eligible for this trial, participants need to be at least 18 years old and have a deep cavity in a molar or premolar tooth. They should be in generally good health and able to give consent. Patients with certain conditions, such as swelling or severe gum disease, will not be included. Throughout the study, participants can expect regular check-ups to assess their tooth health and receive guidance from dental professionals. This research aims to help dentists make better treatment choices for patients with deep tooth decay.
