Discuss the most important features of a good reference book

A good reference book will have both the generic and trade name of the drug. It will contain the necessary information regarding drug doses, adverse effects, drug interactions, contraindications, mechanism of action, and information regarding patient teaching.

What are some reasons that a patient might be noncompliant with medication?

A patient could be noncompliant with medication because of the adverse reactions, he/she did not understand the directions, or he/she does not believe that the medication is necessary.

What should a patient be told about the medication that the dentist has chosen?

A patient should be told the name and dose of the medication and how he should take it. He should be counseled about the additive CNS depressant effects with alcohol, opioid analgesics, and other CNS depressant medications. He should also be counseled about the sedating and amnestic properties of benzodiazepines.

What should a patient be told about an antibiotic?

A patient should be told the name of the antibiotic, the strength of the antibiotic, and how to take it. The dental practitioner should also review potential adverse reactions or symptoms of allergic reactions with a patient and what to do should they occur.

Joe T. is a 50 yr old, 320 pound white male who has been coming to your practice for 2 yrs and he undergoes kidney dialysis. His teeth are in fairly good condition with the exception of one tooth. The tooth is almost dead, it requires a crown, and Joe will need a root canal. He is in pain just thinking about having the root canal. His main concern is adequate pain control after the procedure.

What type of drugs are Valium, Xanax; date rape drug - i.e. flunitrazepam?

Benzodiazepines

Is memory loss a problem with benzodiazepines? What should a patient be told?

Benzodiazepines are associated with anterograde amnesia. The memory loss is limited to events occurring after drug administration and most likely results from impaired consolidation processes that store information. A patient should be counseled about the amnestic qualities of benzodiazepines. She should be instructed not to operate heavy machinery or equipment and to avoid any activity that requires thought or concentration. Lastly, she should have someone drive her to and from her appointment.

The dentist decides to prescribe diazepam which is to be taken the night before her appointment and approximately one hour before her appointment. What is the rationale for using benzodiazepines to treat anxiety?

Benzodiazepines are used to treat anxiety because they have relatively fast onset of action and their duration of action is short, intermediate, or long. These drugs are safe and effective in the treatment of anxiety.

Explain the difference in mechanism of action between the direct-acting and indirect-acting cholinergic agents.

Direct action - Cholinergic drugs resemble acetylcholine and act directly on the receptor. Indirect action - These agents, such as amphetamine, release endogenous norepinephrine, which then produces a response. Depletion of the endogenous norepinephrine with reserpine diminishes the response to these agents. Indirect-acting parasympathomimetics or cholinesterase inhibitors inactivate the enzyme acetylcholinesterase.

Compare and contrast hydrocodone with ibuprofen.

Hydrocodone is an opioid analgesic that binds to κ, μ, and σ receptors located along the pain-analgesic pathways in the CNS (spinal, midbrain, thalamic, and cortical sites of action) and produces altered perceptions and response to pain. Ibuprofen is an NSAID and works by blocking prostaglandin synthesis. The main adverse reactions of NSAIDs are GI, whereas the most common adverse reactions of hydrocodone are CNS related. Hydrocodone has abuse potential, whereas ibuprofen does not. Ibuprofen is ideal for the treatment of mild to moderate pain, and hydrocodone is used to treat moderate to severe pain.

What is hydrocodone and how effective is it in treating or managing dental pain?

Hydrocodone is an opioid analgesic that produces fewer adverse reactions and has less potential for abuse than morphine. However, the risk for abuse with hydrocodone has risen dramatically. It is now a Schedule II controlled substance drug. It is used for the relief of mild to moderate pain in patients who cannot tolerate NSAIDs or in whom NSAIDs are ineffective. It is effective in treating and/or managing dental pain.

Are there any drug interactions with hydrocodone?

Hydrocodone may interact with cough and cold medications and allergy products that are sedating. The combination may cause increased sedation, dry mouth, constipation, and urinary retention. Patients should use caution with driving, operating heavy machinery or equipment, or anything that requires thought or concentration.

Compare and contrast the OTC NSAIDs.

Ibuprofen is the oldest and the most commonly used OTC and prescription NSAID. It is rapidly absorbed orally, and food delays its rate but not its extent of absorption. It undergoes hepatic metabolism and is excreted in the kidneys. Ibuprofen has been proven to be effective in the management of dental pain and is usually the drug of choice. Ibuprofen is dosed every 4 to 6 hours. Adverse reactions include GI upset and some confusion. It is also available in a pediatric dose form in both prescription and OTC strength. Trade names include Motrin IB, Advil, Nuprin, Children's Motrin, and others. Naproxen (Aleve) is similar to ibuprofen but differs in its duration of action and is dosed every 6 to 8 hours for the prescription product and every 12 hours for the OTC product.

Should a patient be concerned about becoming addicted to benzodiazepines? Why or why not?

What are the dental concerns associated with tuberculosis and when is it okay to treat a person with tuberculosis?

The dental concerns associated with tuberculosis are that the patient may have active disease. TB is communicable, so a person with active disease can infect those in the dental office. If a person with active TB seeks oral health care, contact that person's physician and delay health care until the disease is no longer in an active state.

What are the dental concerns associated with hydrocodone?

The dental hygienist should perform a detailed medication/health history to determine whether or not a patient is allergic to opioid analgesics or may require a dosage reduction. Elderly patients, those with prostatic hypertrophy, and those with liver and kidney disease should have their dosages reduced. This will help to minimize or avoid adverse reactions. Other dental concerns include increased risk for sedation and dry mouth.

Is nephrotoxicity and hepatotoxicity only associated with toxic doses of acetaminophen?

The doses required for these adverse reactions are constant and are usually taken over a long period of time. Long-term, chronic dosing could cause these adverse reactions. Those doses and duration used in dentistry are usual doses, yet short in duration, and should not present a significant problem in dentistry.

Compare and contrast the parasympathetic and sympathetic nervous systems. Include neurotransmitters, receptor sites, and effects on innervated organs.

The major neurotransmitters of the sympathetic nervous system are epinephrine and norepinephrine. The receptors are α, β 1 ,and β 2 . Stimulation of these receptors can stimulate the heart, raise blood pressure, and cause constriction of the blood vessels, bronchial smooth muscle relaxation, and relaxation of the GI tract.

What is the importance of the medication/health history?

The medication/health history is necessary in order to safely treat the patient. It allows the dental hygienist to provide the best possible care to the patient.

The potency of a drug can be expressed in terms of the median effective dose (ED 50 ). The ED 50 is the dose of a drug required to produce a specific effect in 50% of the subjects or the dose that produces half of the maximum effect. The median lethal dose (LD 50 ) is the dose when one half of the subjects die.
