22
Q

When can enamel erosion occur for a patient with peptic ulcer?

A

23
Q

Oral complication of PPIs

24
Q

Oral complications of H2 receptor antagonists

A

Toxic effect of bone marrow

Infrequent anemia, agranulocytosis, thrombocytopenia

25
Oral manifestations of agranulocytosis
Mucosal ulcerations
26
Oral manifestations of anemia
Mucosal pallor | Glossitis (depapillation)
27
Oral manifestations of thrombocytopenia (secondary to hemolytic anemia)
Gingival bleeding or petechiae
28
4 extraintestinal manifestations of ulcerative colitis
* Arhtritis * Erythema nodosum * Pyoderma gangrenosum * Eye --> iritis and uveitis
29
3 extraintestinal manifestations of crohn's disease
Peripheral arthritis Erythema nodosum Aphthous (non-specific ulcer in mouth)
30
IBD profile that suits in-office dental work (4 points)
Mild dz: - No symptoms - No fever - < 4 bowel movements/d w/ little or no blood - ESR < 20 mm/hr
31
IBD profile that requires MD consult (4 points)
Moderate dz or severe - 6+/d w/ blood - Fever - Anemia - ESR >30
32
Anti-inflammatory drugs to be avoided in IBD
Aspirin and NSAIDs
33
2 alternatives to aspirin and NSAIDs for anti-inflammation
Acetaminophen (alone or with opioids) | COX-2 inhibitor + PPI
34
Antibiotic to be cautious with in IBD and why
Clindamycin (can lead to C. diff infection --> diarrhea; very strong and can trigger pseudomembranous colitis)
35
Risk of immunosuppressants in IBD
5% pancytopenia | Increased risk of lymphoma and infection (i.e. mono, recurrent fever)
36
4 points of modification for treatment plan in IBD patient if acute exacerbations
* Determine if anxious / stress / depression * Urgent dental care only * Elective dental care rescheduled during period of remission * Assess current dz severity by taking patient’s temperature and brief ROS (diarrheal bowel movement /d w/ or w/o blood)
37
2 points of management for a IBD patient on sulfasalazine
* Review patient’s systemic health | * Blood test (CBC & diff)
38
2 reasons for taking blood tests for IBD patient on sulfasalazine
* Nephrotoxic --> renal function | * Associated with hematologic abnormalities (leukopenia, thrombocytopenia, anemia..)
39
Profile of patients who are at a higher risk of peptic ulcer disease (4 points)
* >65 years of age * Previous hx of ulcer complications * Prolonged use of NSAIDs * Concomitant use of anticoagulants, corticosteroids and bisphosphonates
40
Profile of patients who are at a higher risk of pseudomembranous colitis (4 points)
* >65 years of age * Hx of recent hospitalization * Taking broad-spectrum antibiotics (clindamycin, cephalosporin, ampicillin) or multiple antibiotics * HIV-seropositive status associated with immune suppression
41
2 risk factors for IBD flare up
* Symptomatic | * Fever
42
Consequential risk of having ulcerative colitis
Colon cancer
43
2 oral complications of ulcerative colitis

45
4 areas where pyostomatitis can occur in UC
Labial mucosa Gingiva Palate Tongue (rare)
46
2 oral complications of Crohn's disease
* Mucosal ulceration and diffuse swelling of the lip and cheeks (orofacial granulomatosis) * Oral ulcer ~ linear mucosal ulcers w/ hyperplastic margins or papulonodular ‘’cobblestone’’ proliferations of mucosa (buccal vestibule and soft palate)
47
3 medications that are the usual cause of pseudomembranous colitis
* Clindamycin (2 % to 20 %) * Amipicillin or amoxicillin(5 % to 9 % ) * Cephalosporin 3rd generation (<2%)
48
4 medications that are less frequently involved in the development of pseudomembranous colitis
Maclide Penicillins Trimethoprim-sulfamethoxazole (Bactrim, Septra) Tetracycline
49
4 medications that are rare causes of pseudomembranous colitis
Aminoglycosides Antifungal agents Metronidazole Vancomycin
