Which combo anesthetic has longer duration: Oraqix or Cetacaine?

• A. Oraqix
• B. Cetacaine
• C. Both have same duration
• D. Neither has a longer duration

Answer: (B)

Duration of topical anesthesia in dentistry depends on the agents used and how long they stay active in the tissue. Cetacaine combines benzocaine, tetracaine, and butamben, and this mix includes a long-acting agent (tetracaine) that remains effective longer on mucosal surfaces. Oraqix, on the other hand, uses lidocaine and prilocaine in a gel formulation, which provides shorter-lasting numbness on periodontal tissues. In practical terms, Oraqix typically lasts around 20–30 minutes, while Cetacaine can provide anesthesia for roughly 30–60 minutes. Because of the presence of the longer-acting components in Cetacaine, it stays effective longer than Oraqix.
