Trial Summary

What is the purpose of this trial?This trial tests two methods for filling cavities in back teeth. It focuses on patients who need these specific types of fillings. The study uses visual checks and a special imaging technique to see how well the fillings work.

Eligibility Criteria

This trial is for individuals with irreversible pulpitis, good oral hygiene, and available for the study duration. They must have occlusal caries in permanent teeth (except wisdom teeth) that are periodontally healthy and not require cuspal coverage. Participants need at least 20 teeth in occlusion and be able to isolate the tooth during procedures.

Inclusion Criteria

I have cavities in my back teeth, but not including wisdom teeth.

I have a new or recurring cavity.

The extent of the caries lesion bucco-lingually is likely not to exceed two-thirds of the occlusal table

Exclusion Criteria

I have a permanent nerve damage in my tooth.

I have a tooth that might need to be pulled out due to gum disease.

Participant Groups

The study compares two techniques of preparing cavities for composite fillings: one with a wide bevel and another with a 90-degree angle. It uses visual assessments and Optical Coherence Tomography (OCT) to check how well the filling bonds to the tooth over time.
