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.
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.
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.
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.
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).

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.

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
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)
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
Oral and Systemic Health
Links to systemic Disease
Pregnancy: toxins from bugs in the mouth
Diabetes: have higher risk for periodontal disease, oral health can affect type twos ability to control blood sugar
Medications: people living longer with chronic disease and on more meds with side effects
Other vulnerable populations
Soft issues that relate to overall health and self image of your patients
____ and _____
Communication and Presentation
Activities of Daily Living
Discipline of dentistry concerned with the oral health care of medically-compromised patients … and the diagnosis and non-surgical management of medically-related disorders or conditions affecting the oral and maxillofacial region.
Examples of Oral Medicine
___ ____ ____ ____
____ _____ _____
(have to do with oral cavity)
Blood Supply and Lymphatics
Patients having radiation of head and neck have changes in parotid gland
Can be reversible or irreversible
In some ortho cases, teeth get moved in harmony with each other but not with the tm joint
Some of problems in tmj are bc of joint and some because of muscles of mastication
Many thoughts on ways to treat tmj problems (treat joint or treat muscle)
T_____ not limited to
F____ rich in
Taste receptors not limited to tongue
Floor of mouth rich in blood supply
Rich in Ca
•Why is this important?
Contains comp that can attack cariogenic bacteria
Makes it easier to swallow
Some enzymes aid in digestion
Rich in Ca
•Why is this important?
•Plaque will calcify due to Ca in saliva--> this is known as Calculus or Tarter
•Tends to happen in lower anterior teeth bc of where salivary gland is
Primary FCN of oral cavity
Made up of
Alverolar bone in maxilla/madible
Made up of
- •Periodontal ligament (PDL)
- •Alveolar bone
- Alverolar bone in maxilla is diff then in madible
Diseases of Oral Cavity
•Periodontal Disease: (caused by same thing as caries)
What makes some people more resistant to caries but sus to periodontal diseaseà we don’t know
We don’t see a lot of this in under 30 crowd
See significant perio disease after 30
As they get older, get more resistent to caries but more sus to p disease
Resistant can come from fluoride **
- mouth changes as we age
Abnormalities of Oral Cavity
•Malocclusion: Bad bite
•Leukoplakia: seen in smokers
- those that wipe off can be fungal infections
•Edentulism: No teeth
