U.S., May 29 -- ClinicalTrials.gov registry received information related to the study (NCT06991842) titled 'Effect of Phosphoric Acid Etching Duration on Direct Resin-Based Composite Restorations in Permanent Anterior Teeth' on May 07.

Brief Summary: The goal of this clinical trial is to learn if reducing the phosphoric acid etching (PAE) time affects the performance of direct resin-based composite (RBC) restorations in permanent anterior teeth. It will also learn about the safety of using a shortened PAE protocol. The main questions it aims to answer are:

Does a shorter PAE time lead to more or less marginal staining in restored teeth?

What sensitivity or other clinical issues do participants experience after restoration using different...
