XEROSTOMIA 

 

is a ____ and/or _____ of saliva.

It can be ___ or ____, and may be caused by a variety of ___ or ____ _____ or ______, such as _____, _____, or _____.

can lead to problems because saliva helps _____

Xerostomia (or “dry mouth”) is a reduction and/or change in consistency of saliva. It can be real or perceived, and may be caused by a variety of direct or indirect factors or diseases, such as medications, obstruction or damage to salivary glands, or immunosuppression. Dry mouth can lead to problems because saliva helps prevent tooth decay by limiting bacterial growth and washing away food particles.

2

CARIES

The word caries is derived from the Latin for _____

Caries is an _____ and ____ of tooth structure

caused by ____ ____via the ____ of _____ and other ___ to form ___ and ____.  

 

 The word caries is derived from the Latin for “rotten”.

Caries is an infection and destruction of tooth structure

caused by dental plaque via the fermentation of sugars and other carbohydrates to form lactic and other acids. 

3

SALIVA

 

Saliva contains components that can directly ______________, and is also rich in ____ and ____ that help _____.

Saliva also enhances your ______ and makes it _____.

In addition, enzymes in saliva 

 

 Saliva contains components that can directly attack cariogenic bacteria, and is also rich in calcium and phosphates that help remineralize tooth enamel. Saliva also enhances your ability to taste and makes it easier to swallow. In addition, enzymes in saliva aid in digestion.

ORAL FLORA

 

_____

They form ______ that adheres to _____ _____ in a ____, or ____ commonly called ____.

Dental plaque causes

 

 The bacteria colonizing the mouth are known as oral flora.

They form a complex community that adheres to tooth surfaces in a gelatinous mat, or biofilm, commonly called dental plaque.

Dental plaque causes tooth decay and periodontal disease is a type of biofilm.

5

 

PERIODONTAL DISEASE 

 

Periodontal disease (like dental caries), is an _____ leading to _____ ____ ____ caused by_________.

The basic division in periodontal diseases is between _____ and _____

 

 Periodontal disease (like dental caries), is an infection leading to chronic inflammatory disease caused by bacteria in dental plaque. The basic division in periodontal diseases is between gingivitis (the mildest form, reversible with professional treatment and good home care) and periodontitis (untreated gingivitis extending into the adjacent attachment apparatus).

6

 

 CLEFT LIP / CLEFT PALATE

Cleft lip/Cleft palate is the most common of all ____ ___, and among the most common of all___ ___

These anomalies result from the 

 

 Cleft lip/Cleft palate is the most common of all craniofacial abnormalities, and among the most common of all birth defects.

These anomalies result from the failure of the first branchial arches to fuse.

7

 

 APTHOUS ULCERS

Apthous ulcer is the technical term for _____, the most ____ and generally ___ ___ ___ ____

Exact cause is ___, but the strongest associations are with ____ ____

 

 Apthous ulcer is the technical term for “canker sores”, the most common and generally mild oral mucosal disorder.

Exact cause is unknown, but the strongest associations are with immunologic abnormality and trauma. (Source

8

LEUKOPLAKIA

Leukoplakia is a _____ that cannot be ____ and cannot be _____

It is a clinical term without____

Although most leukoplakia patches are _____ (benign), some show 

 

 Leukoplakia is a white patch of the oral mucous membrane that cannot be wiped off, and cannot be diagnosed clinically as any specific disease entity.

It is a clinical term without histologic connotation.

Although most leukoplakia patches are noncancerous (benign), some show early signs of cancer. (Source: WebMD, Mayo Clinic)

9

Why a “systems-based” approach to the biomedical sciences?


•Relevance to clinical sciences and patient care
•More easily integrate evidence-based approach
•Medical/dental histories and basic science

Systemic Health

11

Links to systemic Disease

  •  
  •   
  •

Cardiovascular Disease

Pregnancy: toxins from bugs in the mouth

Diseases of Oral Cavity

C____

P____ (when)

I____

C____

(____)
