First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tested a gas called Kalinox, a mix of nitrous oxide and oxygen, to help patients relax during dental care. It included 549 anxious or phobic patients, young children, and mentally disabled adults across 36 French dental centers. The goal was to see if the gas reduces pain and makes dental visits easier for both patients and dentists.
