Love Bone, It's So Delightful

How do we describe bony lesions?

they're both flat lesions with a change of shape or color

macule: any change in shape or color that is < 1cm

patch: macule > 1cm

Differentiate macule and patch

vesicle: < or equal to 0.5cm

bulla: > 0.5cm

What are the names for fluid filled blisters? Differentiate them

raised solid lesions

papule: < or equal to 0.5cm

nodule: > 0.5cm (sessile vs pedunculated)

Differentiate papule and nodule

tumor

non-specific for any large, solid mass

pustule

pus-filled elevation of any size

plaque

slightly elevated lesion with large area

keratosis

white, raised lesion caused by an increase in keratin

large, solid swelling

define mass

sessile

dome shaped nodule

pedunculated

she likes this word so it'll be on the exam!

mushroom shaped nodule

atrophy

thinning of the mucosa

erosion

depressed lesion, incomplete loss of mucosa

fissure

linear cleavage of mucosa

ulcer

complete loss of mucosa

scar

result of injury causing mucosal atrophy or hypertrophy with increased underlying collagen

red

eryhthematous

even ; same throughout

homogenous

uneven

variegated

blending with normal tissue

ill-defined/diffuse

wrinkled

corrugated

firm

indurated

fluid-filled

fluctant

ground glass

What type of trabecular pattern is exhibited in this radiograph?

cotton wool

What type of trabecular pattern is exhibited in this radiograph?

checks for periodontal abscesses, sinus tract & vertical fractures

How is probing used for diagnostic testing?

checking for vertical fracture

How is transillumination/bite stick used for diagnostic testing?

checks vestibule for swelling

How is palpitation used for diagnostic testing?

tap on teeth to check for PDL inflammation

How is percussion used for diagnostic testing?

only used to distinguish maxillary from mandibular - same side

How is selective anesthesia used for diagnostic testing?

use gotta percha to locate tooth

How is the sinus tract used for diagnostic testing?

uses cold, sometimes hot

- tests for vital pulp

- must compare results to other teeth

more accurate than electric pulp test

How are thermal tests used for diagnostic testing?

CBCT; PAX (no diagnosis based on x-rays alone)

How are radiographs used for diagnostic testing?

- tests for vital pulp

- must compare results to other teeth

- not as accurate as cold test

not used if open apex

How is the electric pulp test used for diagnostic testing?

percussion sensitivity

How is symptomatic apical periodontitis diagnosed?

periapical radiolucent lesion

How is asymptomatic apical periodontitis diagnosed?

diagnosed with swelling (localized or generalized)

How is acute apical abscess diagnosed?

sinus tract + radiolucent lesion

How is chronic apical abscess diagnosed?
