Summary

This trial tests whether a computer-controlled system for delivering local anesthesia can reduce pain compared to a traditional dental syringe. Dental students receive both methods on separate visits, and their pain, anxiety, and preferences are measured. The goal is to see if the computer-assisted approach offers a more comfortable experience.

Active substance: a computer-controlled local anesthetic delivery system (CCLAD) compared with a conventional dental syringe
What this could lead to: If it works, this could lead to less painful dental injections and a better experience for patients.
What could go wrong: This is a small pilot study in dental students, so results may not apply to the general population. The device may not significantly reduce pain for everyone.
