Condensing Osteitis
mand. 1st Molar most common tooth affected
dense bone with little marrow or CT
usually associated with carious tooth or large restoration
asymptomatic
young adults
no treatment

usually only 1 tooth affected
radiographically – round to ovoid RL area in central portion of RO

appears as slight raggedness or blunting of the apex and can proceed to severe loss of tooth root structure
Generalized root resorption associated with Ortho

most common cyst in oral region
most a symptomatic – found on x-ray
well circumscribed RL at site of tooth extraction

characterized by Epithelial rests of Malassez
localized mass of chronic granulation tissue forming at opening of pulp canal at apex of a non-vital tooth root

composed of a purulent exudates (pus) surrounded by CT containing neutrophils and lymphocytes
tooth associated with abscess is painful and can be slightly extrudedestablish drainage

excessive proliferation of chronically inflamed dental pulp tissue
large carious lesions
young children
red or pink nodule of tissue that often fills the entire cavity in the tooth

Responses caused by caries or trauma

increase in bulk of the free/attached gingiva, especially the interdental papilla; no stippling and rounded margins
local irritants – plaque/calculus
hormonal changes
drugs – Dilantin (phenytoin); Procardia(CCB) and cyclosporin
biopsy to rule out leukemia
gingivectomy to treat

form of denture stomatitis
palatal mucosa is covered by multiple erythematous papillary projections
associated with a denture or partial or orthodontic appliance
surgical removal

caused by an ill-fitting denture and is located in the vestibule along denture border
elongated folds of tissue
excise and form a new denture

FIBROMA”
broad based, persistent exophytic lesion composed of dense, scar-like CT occurs as result of chronic trauma
most < 1cm
most common mass on gingival
removed surgically

bone lesion identical to CGCG with patients who have hyperparathyroidism

occurs in bone of max./mand. – children/young adults Excise
destructive – displacement of teeth

occurs on gingival or alveolar process, women Excise

lesion containing multinucleated giant cells/vascularized CT
occurs only in jaws

common occurring intraoral lesion characterized by proliferation of CT containing blood vessels/inflammatory cells
response to injury
ulcerated, soft to palpation, bleeds easily, deep red to purple
sessile or pedunculated
occurs on gingiva, develops rapidly
occurs in pregnant women – pregnancy tumors
surgical excision

occurs as a result of an obstruction of a salivary gland duct or infection

benign condition of gland characterized by painful swelling/ulceration in area
Usually at junction of hard/soft palate

mucocele in floor of mouth (frog’s belly)
excision

results from obstruction of duct (older than 50 years)

lesion that forms when a salivary gland duct is severed and the mucous secretion spills into the adjacent CT
cyst-like structure
inc and dec in size of time
lower lip most common site (bluish in color if close to the surface)

degeneration of tissues of lips due to over exposure to sun
may also be derived “Angular Cheilitis” at corners of mouth
strong link to basal cell carcinoma/squamous cell carcinoma
use Sunblock

flat, well-circumscribed brown lesion of unknown etiology

flat, bluish-gray lesion resulting from entrapment of amalgam particles into the tissue
most commonly found on gingival or edentulous ridge
can see particles on x-ray

lesion caused by injury to a peripheral nerve
painful
most commonly found at mental foramen surgical excision is treatment

hyperkeratosis associated with use of chewing tobacco
“snuff dipper” – mucobuccal fold
inc risk of cavities, perio disease, attrition, and staining

benign lesion on hard palate associated with smoking – usually pipe or cigar
heavy smoker
hyperkeratinosis with presence of raised red dots seen at openings to minor salivary glands

? – chronic rubbing or friction against mucosa resulting in a thickening of the keratin on the surface
opaque – white appearance and represents a protective response
same thing as a callous on the skin

persistant trauma can lead to a hard, raised lesion

results from some form of trauma
persistant trauma can lead to a hard, raised lesion – traumatic granuloma
healing in 7 – 14 days (if trauma removed)BIOPSY if not healed in 2 weeks (rule out cancer

lesions located at midline of hard palate varying from ulcers to keratotic to exophytic reactive lesions

cavity – sterilizing /cauterizing agent (endo)
causes whitening of area/ulcer if not removed quickly

occurs when patient places aspirin beside a tooth with a toothache
tissue becomes necrotic/white, sloughes off leaving ulcer
ulcer heals in 7 – 21 days
