Correct answer: C — Inhalational sedation with nitrous oxide and oxygen
Nitrous oxide-oxygen inhalation sedation is the most titratable technique because: (1) onset is rapid (2-3 minutes); (2) the level of sedation can be precisely adjusted by changing the N₂O concentration in real-time; (3) recovery is rapid (100% oxygen for 3-5 minutes); and (4) it is eliminated unchanged via the lungs with no hepatic metabolism. This makes it the safest and most controllable sedation modality in the dental office.
