ENDO 1 – Procedure Management, Records, And Clinical Cases Practice Test

What is the recommended acetaminophen dosing after endodontic treatment?

1000 mg every 4-6 hours postop 500 mg every 6 hours 650 mg every 4 hours 1000 mg every 8 hours

Correct Answer:

1000 mg every 4-6 hours postop

Explanation:

Managing pain after endodontic treatment relies on keeping acetaminophen at a therapeutic level while staying within safety limits. A common and effective approach is 1000 mg every 4 to 6 hours as needed, with a maximum of 4000 mg in 24 hours. This dosing provides a strong enough per-dose effect to control moderate post-op pain and maintains relief by not spacing doses too far apart. Waiting 8 hours between doses can leave gaps where pain flares, while smaller doses or unusual intervals may be less reliable for complete analgesia. So, the best option aligns with a 1000 mg per-dose schedule every 4–6 hours postoperatively.
