Evaluating the safety of dental materials in adults

Cohort Biomonitoring Study to Evaluate the Biocompatibilty of Resin-based Dental Materials

Not applicable Interventional Universitaire Ziekenhuizen KU Leuven · NCT02874599

This study is testing if certain dental materials are safe for adults by checking their urine and saliva for chemical levels and looking at changes in their DNA.

What this trial studies

This study involves adult patients who need multiple dental restorations. Participants will provide urine and saliva samples at various time points to measure bisphenol A levels and assess estrogenic activity. Additionally, buccal cells will be collected for DNA extraction, allowing researchers to analyze changes in DNA methylation and hydroxymethylation levels. The goal is to evaluate the biocompatibility of resin-based dental materials used in restorations.

Who should consider this trial

Good fit: Ideal candidates are Caucasian adults requiring multiple dental restorations.

Not a fit: Patients with acute or chronic medical conditions, oral inflammatory conditions, or those who smoke or consume alcohol may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to safer dental materials that minimize health risks for patients.

How similar studies have performed: While similar studies have been conducted, this specific approach to evaluating resin-based dental materials is relatively novel.
