Clinical Study on Reduced Exposure Times for Primary Tooth Fillings

Zusammenfassung der Studie

In cases of treatable caries or defective dental fillings, a new composite filling (tooth-colored plastic filling material) is usually placed to achieve a naturally looking and fully functional dental restoration. The filling is cured by exposing the material to light after it has been placed in the cavity, causing the previously soft material to harden. In our research project, we investigate whether a reduced exposure duration (5 seconds) with increased light intensity (2000 mW/cm²) leads to the same clinical outcomes as the standard exposure (10 seconds, 1200 mW/cm²). The 5-second exposure mode has been successfully used for fillings in adults for years.

Untersuchte Intervention

In our study, all participants will receive two dental fillings. One filling will be cured using the 5-second exposure mode (test group), and the other filling will be cured using the 10-second exposure mode (control group). The exposure duration for primary teeth is usually 10 seconds. In this study, we want to investigate whether fillings placed with the medical product Tetric plus Flow in primary teeth and cured for 5 seconds are effective and safe. For this purpose, aesthetic, functional, and biological parameters will be collected over an observation period of 1 year.
