Final answer:
Oraqix is a topical dental anesthetic that is effective on soft tissues for about 20 minutes, which is the correct answer (b). It combines lidocaine and prilocaine and is typically used for procedures like scaling and root planing. The correct answer is: b) 20 minutes
Step-by-step explanation:
The correct answer is: b. 20 minutes
Oraqix is a dental anesthetic designed for use in periodontal procedures. It is a topical anesthetic gel that combines two anesthetic agents, lidocaine and prilocaine, in a thermosetting system that allows it to become more viscous at body temperature. Once administered to the soft tissues in the mouth, such as the gingiva, it provides a localized numbing effect that is ideal for procedures like scaling and root planing, typically lasting for about 20 minutes. This duration enhances patient comfort while providing sufficient time for most periodontal maintenance procedures without the need for injections.
Although Oraqix's effectiveness can vary slightly based on the individual's absorption and the procedure's specifics, the general effective duration is around 20 minutes. It is important for dental professionals to consider the time frame and apply the anesthetic at an appropriate point in the procedure to ensure optimal patient comfort.
