5 dental impacts of oral contraceptives
- 1. oral mucosa is more resistant to trauma
- 2. increased risk of dry socket during active pill (3 weeks)
- 3. patients on OC are more likely to develop gingivitis
- 4. antibiotic premed single dose will NOT interact with OCs
- 5. greater than 48 hours of dental antibiotics may decrease the effectiveness of OC (i.e. a continuous dose)
How many hours must a patient be on dental antibiotics before the effectiveness of their OC may become decreased?
What are the different categories of diabetic drugs?

Sulfonylureas and Meglitinides
What are 3 sulfonylureas?
- 1. glyburide
- 2. glipizide
- 3. glimepride
Which category of antidiabetic medications is the mainstay for anti-diabetic therapy?

- 2. Rosiglitazone
What are 2 examples of Meglitinides?

- 2. Repaglinide
What is the mechanism of action for sulfonylureas?
increase insulin secretion
What is the mechanism of action of Alpha-Glucosidase Inhibitors?
they decrease carbohydrate absorption from the gut
What is the mechanism of action of TZDs?
they are insulin sensitizers
What is the mechanism of action for Metformin?
increase uptake of glucose and decrease gluconeogenesis
What is the mechanism of action for Meglitinides?
they stimulate insulin secretion
