Question 15

salivary gland stone, precipitation of calcium salts around a central core, can cause obstruction of gland

Answer 15

Question 16

this is a lesion that forms when a salivary gland duct is severed and the mucous secretion spills into the adjacent connective tissue, cyst like structure, most common site is the lower lip, increase and decrease in size of time

Answer 16

-mucocele-

mucous retention cysts-results from obstruction of duct (50 yrs +)

ranula- mucocele in floor of mouth (frog belly appearance), has to be cut out

Question 17

common occuring intraoral lesion chracterized by proliferation of connective tissue containing blood vessels/inflammatory cells, response to injury..sessile or pedunculated

Answer 17

-Pyogenic granuloma-

ulcerated, soft to palpatation, bleeds easily, deep red to purple,

occurs on gingiva, develops rapidly

occurs in pregnant women -pregnancy tumors
surgical excision

Question 18

usually on 1 tooth is affected with this.. associated with inflammatory response in the pulp.. radiographically- round to ovid RL area in central portion of RO

treatment is root canal unless perforation then extraction

Answer 18

internal root resorption

Question 19

degeneration of tissues of lips due to over exposure to sun, may also be derived “angular chelitis” at corners of mouth, strong link to basal cell carcinoma, squamous cell carcinoma.. use sun block to prevent

Answer 19

solar chelitis

Question 20

this is hyperkeratinosis associated with the use of chewing tobacco

Answer 20

-tobacco chewers-

snuff dipper-muccobuccal fold

increase risk of cavities, perio disease, attrition and staining

Question 21

“FIBROMA”, broad based, persistant exophytic lesion composed of dense, scar like, CT

Occurs as a result of chronic trauma

most <1cm

surgically removed

Answer 21

irritation fibroma.. most common mass on gingiva

Question 22

this injury results from some type of trauma..persistent trauma can lead to a hard, raised lesion known as a traumatic granuloma

Answer 22

-traumatic ulcer-

healing within 7-14 days (if trauma is removed)

if not healed in 2 weeks, have biopsy to rule out cancer

Question 23

what are the responses caused by caries or trauma?

Answer 23

inflammation
infection
chronic hyperplastic pupitis
necrosis of dental pulp

Question 24

this is a flat, bluish-gray lesion resulting from entrapment of amalgam particles into the tissue, most commonly found on gingival or endentulous ridge.. particles can be seen on an xray
