Diciplineof dentistry concerned with, oral health care of medically-compormised patients, and diagnosis and non-surgical management of medically-related disorders or conditions affecting the oral and maxillofacial region.
Oral medicine examples
Bleeding gums-means unhealthy gums,medications like antiplatelet drugs ex aspriin, coumadin
JADA (journal of the American Dental Assiciation)
regonizes the link between oral health and systemic disease!
Primary funciton of the Oral cavity
process food (Mastication)
Know the following terms and where they are in relation to one another
Cementum (portion of anatomical rood that covers it's dentin)
Dentin(inside part of tooth coverd by cementum and enamle and can re-mineralize)
Enamle(anotomical crown and covers dentin)
Peridonal ligament (PDL- little fibers that attach the tooth to the aveolar process)
plaque- dental biofilm
Pulp-nerve of the tooth and supplies it's nutrients.
Alveolar process( socket)
Calculus (calcified Plaque that occurs duing higer pH's also called tarter)
Caries- (cavities demineralized her tissue)
Mucosa-involved in absorption and secretion and covered in epithelium
Palate-roof of mouth
What is the anatomy of the oral cavity?
Floor of the mouth
Salavary glands(parotid, sublingual, submandibular are major glands)
Muscles of mastication(temporialis, Masseter, medial petrygoid, lateral petrygoid.)
Muscles of facial expression
Temporomandibular joint (TMJ)(joining of temporal bone and mandible)
What are Carries
Cavities (caused by introducing acidity or sugar in to oral cavity and then this causes an acidic environment which demineralizes enamel)
Gingivitis, and periodontitis
other diseases that can occur in oral cavity
what are snacks that cause caries and what are snacks that don't?
infection, cancer, (aging)
sugary snacks, acidic snacks,
ones that don't are peanuts, or cheese, these are low risk snacks
Abnormalities of the Oral cavity are?
Cleft palate-cranio facial defect at birth
Aphthous ulcer( canker sore, caused by trauma, and immunologic abnormality
Leukoplakia-white patch in oral cavity, usually in users of chronic irritans like smoking
Pulp Replenishment of Dentin
The pulp can replenish the dentin but it does so at a slower rate than a carie spreads.
Examination and diagnosis of oral (and systemic) disease begins with knowledge of?
Anatomy and function
Condition of the oral cavity is an important sign in?
The condition of the oral cavity, especially the teeth and periodointium, provide insight of?
the importance of oral health to the patient
What is Saliva?
tooths 1st defense against cariogenic pathogens!
A symbiotic ecology
protein-rich secretions of salivary glands are
-high # of bacteria
What are the functions of Saliva
-lubrication-moistening of food for swallowing
-antibacterial, antifungal, and antiviral
resists acidic pH which casue caries,
-Preparation for digestion
-Digestion (initiation of digestion from the following enzymes.
-pancrease secretes amylase (break down starches), and ribonuclease and lipase help too
-a defense mechanisism, and it solubalizes materials so we can taste it.
-lubrication for water and mucins aids in speech
maintain pH of upper GI
Maintian health of oral mucosa
Keeps microflora balance which helps prevent oportunistic infections
Cleans mouth and clears esophagus.
Source of Saliva
and which of the glands are serous?
Major salivary glands
-polly ductal and empty secretions through a main duct into the mouth
minor salivary glands (clover shaped
- mono ductal and empty secretions directly into mouth)
Secretory Contributors to whole saliva
Von Ebner's glands
-in moats surrounding the circumvallate and fliate papilla in posterior 1/3 of tongue, anterior to termial sulcus
Unstimulated Whole Saliva
-produced while sleeping, reading, bathing etc.
-protects the dentition and supporting structures.
-unstimulated saliva is what is most suseptible to disease.
Stimulated Whole Saliva
process of stiumlated salive involves numerous and comples neuroogical pathways and one of them is gustatory.
Stimulated vs Unstimulated whole saliva produced ?
unstimulated saliva produces about 1/3 the amount of stimulated saliva
when looking to see if a patient has swolen glands what are you looking for?
What instrument is used to collect whole saliva?
What are the normal flow ranges for stimulated and unstimulated? in a 5 min collection
you are looking for symmetry. if non then probably swolen.
Sialometer is instrument used and collection period is for 5 min.
Stimulated flow rates
Parotid-->unstimulated-->.3 - .5 ml/min
Submandibular and sublingual-->untimulated-->.5 - .7 ml/min
Parotid-->stimulated-->.5 - 3.0 ml/min
Submandibular and sbulingual-->unstimulated-->.5 - 2.0 ml/min
What are the normal Salavary flow Rates
saliva per day? what are the contributions fromt he Parotid, submandibular and sblingual when unstimulated? and Stimulated
