What this trial studies

This clinical trial aims to evaluate the safety of Polymer-Induced Liquid Precursor (PILP) in treating dentin caries in adults. Participants will receive either PILP or a placebo before having a filling placed in a carious tooth. The study involves multiple follow-up visits to monitor for any adverse effects over a six-month period. The primary focus is to determine if PILP can be safely used without causing harm to the tooth or the patient.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 64 with at least one posterior tooth diagnosed with dentin caries that requires restoration.

Not a fit: Patients with known allergies to components of the study device or those with irreversible pulpitis will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a safer and more effective option for managing dental caries in adults.

How similar studies have performed: While this approach is novel, similar studies evaluating new dental materials have shown promise in improving treatment outcomes.
