Case(1)
You complete endodontic treatment on a
32 y.o. male and expect mild to moderate
pain. His medical history is significant for a
recent GI (gastrointestinal) bleed from
stomach ulcers.
Which medication is the best choice? & why?
Ibuprofen, Aspirin or Acetaminophen
5. 5 of 37
Aspirin and NSAID induced GI injury results from two
known mechanisms
1. Local irritation of the mucosal lining allows
diffusion of acid into the lining with subsequent
tissue damage
2. Inhibition of gastric prostaglandins that inhibit
secretion of gastric acid and promote secretion of
cytoprotective mucus
Aspirin and NSAIDs are contraindicated in patients
with GI ulcers

Case(2)
You see a 25 y. o. male with a very painful
abscessed tooth #31 on Monday morning. He
has been in pain since Friday night. He has not
slept in 48 hours and has been taking 6 extra
strength Acetaminophen every 2 hours for the
last two days. He is nauseated, has vomited
several times recently and is very tired.
What is the problem?
What do you do?
7. 7 of 37
Acute acetaminophen overdose
6 tabs = 3 grams q2h = 12 grams in 8 hours.
Usual dosage not to exceed 4000 mg/day
Hepatic toxicity may occur following ingestion of 7.5 to 10 grams
over a period of 8 hours or less
8. 8 of 37
1. Stomach wash and administering
activated charcoal
2. Administration of sulfhydryl
compounds (e.g.acetylcysteine)
which probably
3. replenish hepatic stores of
glutathione.

Case(3)
Your patient a 37 y. o. female has recently
had inpatient Oral Surgery for bone grafting
to the maxilla from the iliac crest. While in
the hospital she was given Ketorolac 30 mg
IV. She also was given Ketorolac 10 mg(disp.
20), one PO qid. She has run out of this pain
medication and would like you to refill it.
What will you do?
10. 10 of 37
Refill the prescription
Give another NSAIDs e.g Ibuprofen
Give acetaminophen
May add narcotic analgesic
11. 11 of 37
Case(4)
A 64 y. o. male presents for treatment of an acutely
painful tooth #13. You determine that the tooth is
non-restorable and requires extraction. He has been
taking 2 ibuprofen every 3 hours to control his pain.
Past medical history is significant for use of oral
anticoagulant(e.g warfarin)as prophylaxis for atrial
fibrillation. The patient supplies you with a note from
his physician that shows that his INR is 2.0 and gives
clearance for extraction of this tooth.
What is the problem?
12. 12 of 37
Oral anticoagulants prevent the synthesis of clotting
factors II, VII, IX and X in the liver (Vitamin K
dependent factors). (Monitored with INR)
Ibuprofen reversibly interferes with platelet
function
Severe bleeding could occur following extraction
13. 13 of 37
Case(5)
You complete the removal of impacted wisdom teeth
on an 18 y. o. female who requests narcotic analgesic
because acetaminophen doesn't work for her.
You prescribe Ibuprofen and narcotic analgesic as
breakthrough medication. The next morning you
receive a phone call that your patient has severe
Nausea and Vomiting and "cannot keep anything
down." The patient states that she is in severe pain
What has caused this problem?
How are you going to treat this problem?
14. 14 of 37
Nausea and vomiting are common adverse side
effects of any narcotic with no documented
differences among agents
Patient has not taken any of Ibuprofen
Instead she has taken only the Narcotic analgesic on
an empty stomach
Because of vomiting she is unable to absorb any of
the pain medication prior to vomiting it back up
15. 15 of 37
Stop the narcotic medication
Take non-narcotic analgesics with foods
Use antinausea medications
Naloxone will not reverse nausea, in fact it
may trigger it or make it worse.

Case(6)
A 35 year old female presents to your office
for evaluation of TMJ pain. She has been seen
by another dentist across town who has been
treating her pain with NSAID and narcotic the
last week. the patient states that she has not
had a bowel movement since she has started
on the pain medication.
What has caused this problem?
How are you going to treat this problem?
17. 17 of 37
Constipation is a common side effect of opioid
medications
Narcotics depress peristaltic contractions
Constipation is dose-dependent and is noted
more with repeated administration
18. 18 of 37
Stop the narcotic analgesic
Prescribe a stool softener, or refer to
primary care MD
19. 19 of 37
Case(7)
You sedate a very nervous 84 y. o. female patient with
Fentanyl and Versed in order to extract an impacted
wisdom tooth. The patient becomes apneic just after
the administration of the sedative medications. You
support her respiration, administer local anesthesia
and extract the tooth in 2 minutes, much quicker than
anticipated. Whenever you stop supporting the
patient's respiration, she becomes apneic
What is happening?
How are you going to treat this problem?
20. 20 of 37
Respiratory Depression
All opioids depress respiration
Caused by a dose dependent
decrease in the response of the
respiratory center to carbon
dioxide
21. 21 of 37
Continue to support the patient's respiration
OR
Administer Naloxone.
22. 22 of 37
Case(8)
A 45 y. o. female patient is transferred to you for

then narcotic, He recently refused to refill any
prescriptions and instead referred her to you for
management. While in your office the patient develops
goose bumps, dilated pupils, nausea and becomes
anxious and somewhat hostile.
What is happening?
