Summary

This study compares three different dental adhesives used to fill non-carious cervical lesions, which are tooth defects not caused by cavities. Thirty healthy adults aged 18-55 will receive restorations using one of the adhesives, and the team will check how well they hold up after 12 months. The goal is to find which adhesive performs best in terms of survival and quality.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
dental adhesive (G2 Bond Universal, Scotchbond Universal Plus, Tokuyama Universal Bond II)
What this could lead to
If successful, this trial could identify which dental adhesive is most effective for repairing tooth lesions, improving dental restoration outcomes.
What could go wrong
This is a small, early-stage trial with only 30 participants, so results may not apply to everyone. The study only lasts 12 months, so long-term performance is unknown.
