Unit IV Flashcards
inflammation or infection of the salivary glands
Sialadenitis
What salivary gland is most commonly infected?
parotid
obstruction of a duct by a calculus like mass. ( actual blockage)
sialolithiasis
where is the most common place to get stones?
sub mandibular
name of thing blocking structure?
sialolith
name the 3 sets of salivary glands
submandibular, sublingual,parotid
how much spit do you make a day?
1 liter
not enough salivation being made is called?
hyposalivation
if you experience hyposalivation, you are at an increased risk for what?
oral candidiasis, lichen planus, apthous ulcers, & more caries
when the body turns on itself and produces less saliva
autoimmune sialadentitis
when EVERYTHING IS DRY
sjogrens syndrome
epidemic parotitis is also referred to as?
MUMPS
inflammation in salivary glands and gonads. Viral transmission by close contact or droplet
Epidemic Parotitis (MUMPS)
pussy or cloudy infection of parotid gland, cloudy is what indicates
supparative parotitis
mucous extravasation phenomenon or mucous retention cyst are two different types of what?
Mucoceles
a collection of saliva in the connective tissue which becomes walled off by connective tissue. Almost always on the lower lip. The DUCT IS KINKED. INABILITY OF SALIVA TO EXIT DUCT
mucous extravasation phenomenon
obstruction of salivary flow by a calculus mass. (salolith) most common in submandibular glands CAUSE BLOCKAGE
mucous retention cyst ( obstructive sialadenitis
found in the floor of the mouth always, under the tongue,bluish in appearance, large rapid growth, will get worse & worse, must have surgery
Ranula
how much saliva is produced at night
very little. about 10ML
increased saliva flow
sialorrhea
this is when a patient tells you they have hyposalivation, what is this called?
xerostomia
causes of xerostomia?
everything
Mixed salivary tumor is also called what?
Pleomorphic adenoma
a glandular tumor, most common benign tumor of the salivary glands, should be surgically removed, not a high re-occurrence rate, painless, biopsy tells us, has different types of salivary cells most occur in the parotid gland
mixed salivary tumor or a pleomorphic adenoma
benign tumor of old age, appears as a swelling of the salivary gland, no fluctuation in size from time to time. NOT a big deal
oncocytoma
cancer, surgical removal affects major & minor salivary glands, when major, it effects the parotid, when minor, it effects hard palate, roof of mouth. Most common type of salivary gland cancer in children. More common in older women, survival rate is 90% when found early Painless,
mucoepidermoid carcinoma
carcinoma, effects women later in life, painful, surgical removal, biopsy, usually in palate in minor salivary glands, PAINFUL, metastasizes late in course of disease,
adenoid cystic carcinoma
Functions of saliva
buffer PH of mouth, carries stuff to teeth, moistens food, cools or warms food, helps kill bacteria, antimicrobial agents, lubricates so it doesn’t stick, helps with speech, enhances flavors
mouth droops, eye cannot close, difficulty with speech and mastication, paralysis of the muscles supplied by the 7th cranial nerve. Etiology is unknown
bells palsy
pain along the course of the distribution of the 5th cranial nerve, Etiology : Virus, arteriosclerotic changes, reflex vasoconstriction. Transient unilateral pain in the face often precipitated by touching a TRIGGER zone. most often on the right side of he face in middle aged people
Trigeminal neuralgia
TMJ Dysfunction disorder
pain in the joint area associated with dysfunction of the muscles of mastication. Limited motion, joint tenderness, noise in the joints, deviation on closing. Possible causes: tension, functional malocclusion, articular disk and join asymmetry and muscular dysfunction 60% in women over 30.
Inflammation with pain and swelling
rheumatoid arthritis
destruction of joint cartilage with subsequent calcification of the joint surface with possible ankylosis
osteo arthritis
infection spread from other area, pain, limited motion, pus
suppurative arthritis
usually from a blow to the symphsis area in a backward and upward direction, usually at the neck of the condyle pain, swelling, possible limitation of motion, deviation, malocclusion.
fracture
external force is the cause, severe pain, limited motion, often malocclusion, no significant findings on xrays
sprain
caused by some act that exceeds the nrmal range of opening, i.e laugh, yawn, dental procedure, general anesthesia, open mouth, sever pain and often panic, cannot replace jaw into proper position
dislocation
hyper mobility of the joint is the primary cause, condyle is dislocated to the anterior surface of the eminence, transient and localized pain, pt can replace jaw in proper position.
subluxation (partial dislocation)
trauma to the condylar growth centers resulting in cessation of condylar growth. small mandible, difficult mastication, speech defects, psychological maladjustment
micrognathia
mass of inflammatory granulation tissue or epithelial papilloma, may block and decrease drainage of the sinus
polyps of the sinus
retention cysts developing from mucous gland of the sinus mucosa, asymptomatic can sometimes been seen on xray as a dome shaped soft tissue opacity
mucocele
abnormal passage connecting the sinus to the oral cavity. most often occrs after extraction of upper posterior teeth.
traumatic oroantral fistual
root tip is pushed into the sinus, causes inflammation/infection of the sinus with pressure and pain
root in maxillary sinus
direct extension of infection from nasal cavity, usually after an upper respiratory tract infection. pain over maxilla increased when head is lowered, pressure sensitive.
Maxillary sinusitis
