abcess

cyst

ulcer

localized collection of pus, commonly caused by bacterial infection.

enclosed pouch or sac containing fluid or semi-solid material

disruption of the superficial covering of mucosa or skin

small elevation that contains fluid

leaves superficial ulcers upon rupture

localized collection of blood 

well defined and turns a dark color with tie

vesicles

hematoma

petechiae

ecchymoses

pound, pinpoint non-raised, purplish-red spots caused by mucosa or dermal hemorrhage

large, purplish red areas caused by blood under the skin or mucosa

turns a blue to yellow color

dental caries

pulpalgia

pulpitis

periapical abcess

necrosis

caused by streptococci

first appears as chalky whit spots on enamel(incipient)

indicates decalcification 

arrested if it dosent continue, will be dark and hollowd out

when a dental caries occurs where there is already a restoration.

Develops in depressions of tooth surfaces

usually on the proximal surface

pain in the dental pulp

short sharp shooting pain that's worse when lying down or climbing stairs

inflammation of the dental pulp

results from dental bacterial infection or a fractured tooth

dull ache that can progress to severe, pulsating pain

pulp becomes inflamed

smells pus-like

ulcers form in pulpal canal, can spread to the bone

tooth feels "high" when biting, sensitive to the touch

death of the tissue

may not be in any pain

smells foul, rotten

Periodantal

bleeding with brushing, tender, red swollen gums, tooth shifting, tooth elongation, mobile teeth, purulent exudates in between teeth, halitosis.

inflammation of the gingival tissue

most common gingival disease

starts at the tip of the papillea, results in swelling and loss of texture, easy bleeding.

redness, swelling, px, accumulation of calculus, bleeding, film and necrotic (white) tissue that can be wiped off leaving a raw red wound.

ulceration leaves a punched out appearance of gingival crest 

unpleasent odor and foul taste

Chronic inlammatory condition involving gingival, periodantal membrane and alveolar bone

results in loss of bone, periodantal pocket formation, increases tooth mobility

gingival becomes bluish red

inflammation forms at the apex of the tooth

Gingiva bleeds easily, calculus forms shelf-like projection

interdental papillae is destroyed 

results in loss of teeth

results from long, continuous irritation.

surrounding gingival becomes inflamed and swollen

inflammation of gingival around a partially erupted tooth

most common with wisdom teeth

gingival flap may become infected

canker sores, painful ulcerations

seven to ten day healing time

type 1 is oral

type 2 is genital

Candidiasis

Hairy Leukoplakia

Kaposis Sarcoma

fungal, red or white in color

viral tongue infection

white, slightly raised lesions

loss of substance of a tooth from a wearing away process caused by teeth against teeth
