Quiz 4. Hose Defense Mechanisms in Oral Cavity

Question 1

If there’s enough bacteria what happens?

Answer 1

Infection

Question 2

Profileration

Answer 2

Multiplication of bacteria

Question 3

The Mouth is the beginning of infection

Answer 3

Gateway to GI

Has many defense systems

Question 4

Defense systems

Answer 4

Anatomic Barriers
Normal Oral Flora
Immune Systems
Saliva

Question 5

Anatomic Barriers

Answer 5

Epithelium (keratinized) and an ideal dentition

Can’t cause infection w/o getting past this barrier

Question 6

Normal Oral Flora

Answer 6

Bacteria that discourage colonization

Question 7

Immune System

Answer 7

Cellular and humoral components

Question 8

Saliva

Answer 8

Contains immunoglobins

Question 9

What lacks keratin and is susceptible for invasion?

Answer 9

Junctional epithelium (where perio pocket is)

Question 10

Which epithelium is highly vascularized?

Answer 10

Mucosal

Question 11

What are anatomic situations that give pathogens an advantage to colonize?

Answer 11

Restorations w/ overhangs, lack of interdental papillae, perio pockets, drifting or crowded teeth

Question 12

Pyogenic graulomas

Answer 12

Associated with prego women

Not associated with bone loss

Question 13

Tooth enamel is constantly

Answer 13

undergoing a process of demineralization and remineralization

Question 14

Demineralization is reversible

Answer 14

Saliva

Flouride (Inhibits demineralization, systemic, topic, restorations)

Question 15

What’s in normal oral flora?

Answer 15

Saliva pH
Water content in saliva
Saliva as a buffer

Question 16

Lymph portion of Oral Cavity

Answer 16

Cellular (T-cells from Thymus)
Humoral (B-cells from Bone Marrow)
Both parts of lymph system are involved in defending the body

Question 17

Candida Albicans

Answer 17

Yeast organism
Kept in check by saliva, oral flora, a T-cells
If get past any of these it can cause an infection

Question 18

What is prevalent in acute inflammation?

Answer 18

Neutrophil

Question 19

Blood in the Immune System

Answer 19

Granulocytes find and attack foreign invaders

Question 20

Saliva in promoting homeostasis

Answer 20

Salivary flow functions continuously
@ Sleep- lowest
@ Food ingestion- greatest

Question 21

What does the Parotid gland secrete?

Answer 21

Sodium Bicarbonate

Question 22

Sialorrhea

Answer 22

High saliva flow

Question 23

Sialoliths

Answer 23

Saliva stones

Question 24

Sjogren’s Syndrome

Answer 24

Autoimmune associated w/ other autoimmune diseases

All membranes in body are drier

Question 25

Organic Components of Saliva

Answer 25

Salivary proteins

Question 26

What do salivary proteins do?

Answer 26

Control status of Ca and P in saliva | Prevent rapid drop in pH

Question 27

What do salivary mucins do?

Answer 27

Help clear carbs from mouth and protect against caries Help swallow food Regulate enzymes that are responsible for tissue repair

Question 28

Immunoglobulins

Answer 28

Antibodies made of protein | Defend body against all types of infection even when there is none (ex: allergic reaction)

Question 29

IgM

Answer 29

Largest, earliest to appear Found in blood Can't exit in circulatory system

Question 30

IgG

Answer 30

Most abundant for food allergies

Question 31

IgD

Answer 31

Smallest concentrations linked to IgM

Question 32

IgE

Answer 32

Widespread throughout the body | Found in blood, defense against parasitic infections (fights cancer cells)

Question 33

IgA

Answer 33

Initiates inflammatory process and prevents both bacteria and viruses from adhering to mucous membranes Found in tears and saliva Most important to dentristy
