18
Q

T or F, asthma is irreversible.

A

False, asthma is in fact reversible.

19
Q

What are some risk factors associated with asthma?

A
  • Family
  • History of severe respiratory infection
  • allergic conditions
  • Occupational hazards
20
Q

In severe asthma, what would occur to the smooth muscle of the airways?

A

Their would be:
- Constriction
- Thickening
- Hyperresponsiveness

21
Q

In severe asthma, what would occur at the sub-epithelial layer?

A

Inflammation + fibrosis.

22
Q

In severe asthma, what would occur to mucous secretion + mucus clearance?

A

There would be HYPERsecretion of mucus + impaired mucus clearance.

23
Q

In severe asthma, what would occur in the eosinophil/neutrophil count in the airway of the lumen?

A

There would be an increase in eosinophils + neutrophils

24
Q

What are the symptoms of asthma?

A

1.) Dyspnea
2.) Cough
3.) Wheezing
4.) Weakness
5.) Night cough
6.) Headache
7.) Tachycardia
8.) Allergy
9.) Shortness of breath

25
Q

What are medical managements used for asthma?

A

1.) Limit exposure to triggers
2.) Monitor respiratory functioning
3.) Corticosteroids (if chronic)
4.) Bronchodilators (if acute)

26
Q

What are some dental managements used for asthma?

A

1.) Inhaled medications
2.) Mouth breathing.

27
Q

What are some problems associated with using inhaled medications as a form of dental management for asthma?

A
  • Corticosteroids: risk of developing candidiasis or other infections
    -Beta agonists: Reduces salivary flow + decreases plaque pH
28
Q

What are some problems associated with mouth breathing in patients who have asthma?

A
  • Halitosis (bad breath)
  • Ortho considerations
  • Caries risk
29
Q

What are some treatment planning considerations for patients with asthma?

A

1.) Risk management
2.) Stress/anxiety management
3.) Having a rescue inhaler accessible
4.) Upright chair position for better tolerance
5.) Emergency preparedness

30
Q

What is tuberculosis?

A

It is an infectious disease caused by Mycobacterium tuberculosis.

31
Q

How is tuberculosis spread amongst individuals?

A

It is spread through inhalation of infected droplets.

32
Q

Where does tuberculosis primarily impact in the body?

A

It primarily impacts the lungs (but can infect anywhere aswell)

33
Q

What occurs to the bacteria in tuberculosis when it is ingested by the macrophages?

A

It begins to replicate itself.

34
Q

What occurs to the walls of the lungs in tuberculosis?

A

It begins to destroy the walls of the alveoli causing cavitation & reactive fibrosis.

35
Q

What differs between a latent TB infection & TB disease?

A

1.) It can live in the body but doesn’t grow
2.) Doesn’t make someone feel more sick
3.) It does NOT spread from person to person
4.) has the potential to advance to TB diseases.

36
Q

What are some symptoms of tuberculosis?

A

1.) Severe prolonged cough
2.) Chest pain
3.) Night sweats
4.) Increased body temperatures
5.) Decreased appetite
6.) Weakness or fatigue
7.) Weight loss
8.) Intoxication

37
Q

What would be the biggest result of latent TB infections?

A

It would appear asymptomatic.

38
Q

What would be the medical management used if TB infections were latent?

A

It will not treatment unless they are at high risk for disease progression.

39
Q

What would be the medical management used if TB infections were active?

A

2-7 months of isoniazid + rifampin + ethambutol + pyrazinamide

40
Q

What would be the medical management used if TB infections were confirmed with multi-drug resistance?

A

8-20 months of pyrazinamide + a fluoroquinolone, injectable drug - (amikacin or kanamycin), ethionamide, & either cycloserine or para-aminosalicylic acid

41
Q

What are dental managements used for patients with Tuberculosis?

A

1.) Medical hx check
2.) Medical consult

42
Q

What dental managements would take place if the patient is treated for active tuberculosis?

A
  • Chemotherapy for 2-3 week
  • Confirmation that patient is non-infectious
  • No complicating factors
43
Q

What are some treatment planning considerations for patients with tuberculosis?

A

1.) Universal precautions

2.) Reduce risk of spread:
- airborne isolation rooms
- high volume evacuation
- aerosol-generating procedures
- UV irradiation

3.) Risk of bleeding while on chemotherapy
4.) Ability to tolerate care
