High Palate
Hypoplastic Molars
What medications should be avoided when treating Asthmatic patients and why?

What is the relationship between GERD and Asthma?
GERD may trigger Asthma
Acid reflux may trigger a protective nerve reflex. This nerve reflex causes the airways to tighten in order to prevent the stomach acid from entering the lungs. The narrowing of the airways can result in Asthmatic symptoms, such as shortness of breath.

may be prescribed a low-dose inhaled corticosteroid medication.
What is Asthma?
CHRONIC disorder of the airways characterized by variable and recurring symptoms, airway obstruction, hyper responsiveness, and underlying inflammation.
- Bronchoconstriction following irritant exposure
- Airway Hyper responsiveness
- Airway Edema and Mucous Secretion
Signs and Symptoms of Asthma
Signs:
Wheezing
Tachypnea
Symptoms: Wheeze Shortness of Breath Chest Tightness Cough 😷
Asthma and NSAIDS relationship
NSAIDS should be used with caution in all children with Asthma: 4% of asthmatics are allergic to aspirin and other NSAIDS.

What is a common oral manifestation of inhaled corticosteroid therapy?
Oral Candidiasis
Is Nitrous Oxide contraindicated in Asthma patients?
