3. Our presentation deal with :
Common disease of
the respiratory tract
and their relation to
dentist in 25 slide

4. The Respiratory System
The tube which carries the air from the mouth is called the Trachea
or Windpipe, this later divides into two at which point it becomes the
Bronchi and divides the air equally to each lung. Once the air enters
the lungs it passes through a fine spongy structure which contains
an extensive network of blood vessels, these vessels bring carbon
dioxide into the lungs for removal, and take oxygen from the lungs to
the body.
This is collectively known as the respiratory system.
It deals with the exchange of gases (i.e oxygen & carbon dioxide) in
and out of our bodies.

5. Sinusitis
 inflammation of the epithelial
lining of the paranasal
sinuses.
 causes mucosal edema and
increase in mucosal
secretions.

6. Relations To Dentistry
→ Patients complain of tooth ache when they have sinus
infections therefore it is important to differentiate between a
odontogenic infection and a sinus pain.
→ Chronic sinus infections causes a patient to breath through
the mouth leading to dry mouth and is susceptible to
gingivitis.
→ Use of decongestants causes dry mouth.
→ Use of antibiotics that patients has been used for another
condition, even in increased dosage will not work because
the body has gained resistance to it.

7. Viral Upper Respiratory Infections
 Viral infections are the most
common cause of acute
respiratory illness in children.
 It is transmitted by person-to-
person contact through
respiratory droplets

8. Relation To Dentistry
→ The most common oral manifestations of this is
the presence of small round erythematous
macular lesions on the soft palate and the
enlargement of lingual tonsillar tissue at the
lateral borders of the tongue.
→ Treatment for upper respiratory infections are
decongestants which causes a decrease in
saliva flow leading to xerostomia.

9. Laryngitis &
Laryngotracheobronchitis
 Laryngitis is the inflammation of the larynx
caused by viral infections.
 Laryngotracheobronchitis is an
inflammation involving the larynx, trachea
& lungs also due to viral infections.
 Patients with laryngitis often complain of
fever and sore throat and later coughing.

10. Relation To Dentistry
→ Medications used such as Corticosteroids
for reducing vocal cord inflammation, used
over a period of time causes candidosis.
→ Antibiotics used for the bacterial infections
would not be able to be used when
antibiotic armamemtarium is given. And
anitbiotics used over a period of time
causes candidosis.

11. Pharyngitis & Tonsillitis
 It is the inflammation of
the pharynx & the
tonsils which is due to
either viral or bacterial
infections.
 Caused by the group A
β-hemolytic

12. Relation To Dentistry
→ Patients with GABHS infections should
thoroughly clean their tooth brushes or
removable orthodontic appliances or rinse
it with sterile water.

13. Lower Airway Diseases
 Acute Bronchitis
 Pneumonia
 Asthma
 Chronic Obstructive
Pulmonary Disease

14. Acute Bronchitis
 is an acute respiratory
infection involving the
trachea and bronchi (large
airways).
 Caused by either viral or
bacterial infection.Patients who take amoxicillin should be prescribed another
type of antibiotic when it is needed for an odontogenic
infection.

15. Pneumonia
 Is an infection or
inflammatory illness of
the lung.
 Caused by viruses,
bacteria and fungi
(rarely).
 Signs and symptoms
include, cough, sputum

16. Relation To Dentistry
o Aspirations of oral cavity secretions which contains oral
bacteria & pneumonia causing pathogens into the respiratory
tract, could cause pneumonia.
o Inflammatory products from the gingival tissue and
pathogenic bacteria can be aspirated into the lower airway
promoting lung infection.

17. Asthma
 Chronic inflammatory disorder of the
airways in which it is reversibly narrow.
 Narrowing of the airways obstructs
airflow and breathing becomes difficult
to the patient.
 Asthma could be developed from
factors such as a family history of
asthma, respiratory infections and

18. Relations To Dentistry
 Dental products and materials
such as toothpastes, fissure
sealants, tooth enamel dust and
methylmetacrylate is associated
with asthma.
 Oral manifestations include
candidiasis, decrease in salivary
flow and increase in calculus and

19. Chronic Obstructive Pulmonary
Disease
 COPD refers to chronic bronchitis and
emphysema, a pair of two commonly co-
existing diseases of the lungs in which the
airways become narrowed.
 This limits airflow causing shortness of breath.
 COPD is caused by noxious particles or gas,
most commonly from tobacco smoking, which
trigger an abnormal inflammatory response in
the lung.

20.  Oral manifestations of COPD are halitosis,
Oral cancer, periodontal infections and tooth

21. Dental Management For Patients With
Respiratory Disease.
 Consultation with patient’s physician before
any treatment.
 Review the patient’s medical history to see if:
- severity of the disease
- if they have taken corticosteriods
- the medications taken by the patient
 For asthmatic patients, remind them to bring
their inhalers.

22. When Performing Treatments:
 Chair to be in position where patient can
breath easily.
 Perform daily bio-film control measures
on teeth and dentures.
 For local anesthesia, avoid using
epinephrine for asthmatic patients.
 Availability of nitrous oxide or oxygen for
patients with upper respiratory infection.

23.  Allergy to antibiotics.
 Avoid aspirin or aspirin containing
analgesics for patients who have aspirin-
induced asthma.
 Advice on using antimicrobial mouth
rinse.
 Avoid triggering a hypersensitive airway
When Performing Treatments:
CONT

24.  Follow standard precautions for infection
control.
 Do NOT use equipments that produce
aerosols. Eg. Ultrasonic scalers and
polishing because of aspiration risks.
