Question

Mandibular buccal Infected Cyst | Chapter 1

Answer 1

Well-defined, Patient: More in males Age: 8-13, Site: Mandible around 1st and 2nd molars most common, from cervix to root bifurcation on tooth. Appearance: They occur with mandibular buccal swelling and inflammation, suppuration and pain. Can displace tooth lingually., often bilateral DDX Langerhans TX: Enucleation

Answer 2

Ill-defined Patient: No gender preference- depends on original cancer for females- breast, prostate male Age: Again depends on original cancer usually older but sometimes in the 40s Site: Rare in oral cavity 1-2% of all lesions and more unlikely to both mandible and maxilla Appearance: More often RL than mixed or RO and usually in one area. Prostate makes mixed sometimes

Answer 3

``` Well-defined multilocular RL Patient: No gender Age: 23-30 rare over 50 or under 10 Site: Posterior Mandible Appearance: Expansile multilocular or destructive mottled RL so appearance varies and can show septa and expansion, resorption and perforation such as this case. Margins can be corticated and scalloped. TX: resection or curettage Tendency to recur ```

Answer 4

Well-define, Mix Patient: No gender Age: Average 14 but any Site: Compound more in anterior- More common in maxilla, usually associated with unerrupted teeth. Complex more common in posterior. Appearance: Well circumscribed, RL with mottled appearance from radio-opaque pieces of undeveloped tooth structure. TX: Surgical excision No reccurance

Answer 5

Well-defined RL single Patient: Males Age: Most common 10-40 but can occur at any age Site: 70-80% posterior ramus- Molar area most common but can happen anywhere, Appearance: Unilocular or multilocular (can have satelite or daughter cysts)- Can be well defined and corticated and scalloped or smooth between teeth, displaces teeth; can be mildly expansile-rarely and, grow anterior posteriorly. Like to reoccur, parasthesia if involves nerves TX- surgical removal and carnoys cauterization High recurrence rate Assoc with bifid rib basal cell Nevus syndrome

Answer 6

Well-defined, single Patient: 70% male Age: Average 38, Site: 2 to 1 mandible- more common in posterior, most associated with impacted teeth- over 50% Appearance: Less aggressive than OKC but can get big, not as common as OKC though and histology could rule it out. 50% associated with impacted teeth. Close cousin to OKC-Dont use on same DDX TX Curretage

Answer 7

Well defined, single, RO Patient: 2:1 males Age: Any- but average age is 30 Site: Common bone neoplasm but not as common in the mouth Appearance: Central osteomas are all RO and composed of dense bone and not separated from surrounding bone by a capsule. They have been known to displace teeth and can push up and grow out of the alveolar ridge. Peripheral like inferior mandible border. Gardner's syndrome is auto dominant= multiple osteomas and intestinal polyps TX: Surgical, no recurrence

Answer 8

Ill-defined, mixed Focal chronic sclerosing osteomyelitis: Maybe but: Patient: Any gender Age: Before the age of 20 usually Site: Apex of a tooth with previous deep caries or restoration Appearance: Mixed lesion at apex of tooth of dense bone Chronic sclerosing osteomyelitis: Ill defined, pain Patient: Any gender Age: Mostly adults to older patients -acute any age don’t use on ddx Site: Apex of a teeth in the jaw bones- mostly mandible Appearance: Mixed lesion at apex of tooth of dense bone and ill defined RL, irregular and moth eaten bony sequestra appearance often in reaction to an infection or inflamation. There does appear to potentially be some bone loss so this could be in response to periodontal problems. Chronic diffuse sclerosing osteomyelitis: Maybe but: Patient: No gender or race- some say 2 to 1 female Age: Adults to older patients Site: Mostly mandible, unusual to be in both maxilla and mandible, but perhaps it is in reaction to periodontitis which would occur on both arches. Appearance: Diffuse bone sclerosis, cotton wool, a mosaic pattern of RO and RL Juvenile mandibular osteomyelitis: Possible but: Patient: Females mostly Age: 6-12, so the patient is a little old Site: Mainly mandible Appearance: Bone and soft tissue swelling, diffuse bone sclerosis, ground glass or cotton wool TX- treat cause, steroids antibiotics

Answer 9

``` Ill-defined, multi or single RO Patient: No gender Age: Any age Site: Any site Appearance: Dense thickened bone lesions that can go between teeth but rarely fuse or push teeth- usually less vascular. Ideopathic, inflamatory, developmental ```

Answer 10

Ill-defined Patient: Males Age: Average 30-33 so patient is a little old Site: Equal distribution between mandible and maxilla Appearance: Expansive in all directions, range of appearances from RL, mixed, and RO with dense sclerosis and ill-defined. It can have a sunburst appearance and is malignant. It also ranges from painless to pain if nerves are involved. Most common malignant tumor of bone. Can displace teeth.

Answer 11

Well-defined Patient: Any Age: Any, adults Site: Apices of teeth where the nerve is necrotic, often there are large fillings or decay Appearance: Round area of radiolucency at apex of tooth, size, exact shape and cortication is variable, tooth must be non-vital. Can cause resorption. Teeth often have large fillings, decay or history of trauma.

Answer 12

Ill-defined, mixed Patient: Females 14:1- black Age: Adults Site: Most often apices of mandibular incisors, vital teeth Appearance: Diffuse to corticated depending on stage, Starts RL then gets flecks of RO, progressing to an RO ball with thin RL rim. Teeth are vital TX- None

Answer 13

``` Patient: No gender Age: Any age Site: Gingiva of Mandible Appearance: Firm or hard small, well circumscribed, slow growing nodule on the gingiva, can displace teeth, TX surgical good prognosis ```

Answer 14

Well-defined- but don't use on DDX Patient: Any Age: Any Site: Where a tooth never was- common in 3rd molar areas Appearance: Develop at a spot where a tooth never developed. Don’t use on DDX on test. Unilocular or multilocular, well-defined but can have a sclerotic border, can be expansile. Given the still has #16, he may have never had his other 3rds come in and never had his wisdom teeth removed. These appear very similar to OKC and could be ruled out by knowing his dental history. TX Curettage

Answer 15

Patient: Any gender Age: Any age Site: Gingiva most common orally Appearance: Rapidly growing, well demarcated, nodule can be blueish, pink or white, Also can be ulcerated or hemorrhagic. Knowing the history could rule this out or not.

Answer 16

Well-defined, RL, Unilocular but can have multiples Patient: No gender preference Age: 11-67 Site: No preference Appearance: Presents as a RL triangle narrower at occlusal area and wider at roots. Can displace teeth. Can present in multiples- rarely get big. Usually not corticated. Pain TX: Curettage

Answer 17

Well-defined, single Patient: Males Age: 10-20 Site: Posterior Mandible but anterior is a good location too Appearance: Well circumscribed with defined border that is sometimes sclerotic and scalloped that squeezes in between teeth, often asymptomatic, sometimes can displace teeth and while not consistently this large, they can get big. Above IA and below teeth. Etiology trauma. TX: Exploratory Surgery

Answer 18

No gender, kids around erupting teeth crowns. Well circumscribed, fluctuant, translucent or purple red (hematoma) RL around crown of erupting teeth which disappears when tooth erupts

Answer 19

Auto dom Starts at puberty to early 30s sometimes early as 7 and late as after 40 Assoc with multiple OKC Basal Carcinomas Intracranial Calcifications Hypertelorism/frontal bulging/ sunken eyes heavy fused eyebrows and jaws

Answer 20

White nodules on alveolar ridge, filled with keratin, go away with eruption Similar nodules- Epstein’s pearls- mid palatine raphe Bohns nodules- palate especially at junction of hard and soft palate

Answer 21

``` Common 30-50 but any age and gender Usually asymptomatic unless infected Bilateral round ovoid or heart shaped well defined RL, can push roots of incisors tipping the teeth. TX Curettage when symptomatic ```

Answer 22

Epstein’s pearls Bohns nodules Filled with keratin go away on their own

Answer 23

``` Any age but 50% under 20 80% below hyoid Firm cystic mass under chin on midline Asymptomatic unless pressing on throat, slow, maybe fistula TX surgery Low recurrence ```

Answer 24

Swelling of upper lip and gingiva by lateral and canine that can elevate ala of nose Asymptomatic unless infected and an drain to nose TX surgical Low recurrence

Answer 25

Any gender and age Floor of mouth, ventral tongue, tonsil area most common Small yellowish/whitish raise lesion can be side of neck too

Answer 26

Common on skin, rare in oral cavity Lips and tongue Midline floor of mouth is dermoid cyst Nodular fluctuant subcutaneous swelling , white or yellow in color TX surgical

Answer 27

Adult often edentulous Females 75% Posterior Mandible 70% Ill-defined RO of variable size

Answer 28

Any age Males Lower mandible, below ia round to oval, bilateral or unilateral RL well defined filled with normal tissue No tx

Answer 29

``` Middle age Mainly mandible Small firm well define nodule on gingiva TX surgical excision Recurrence rare ```

Answer 30

Adults Ave 36 30-70 Posterior mandible Aggressive, transformation and metastasis Ill defined destructive and irregular RL

Answer 31

Middle age females like peri apical osseous dysplasia just around one tooth in the back…. 3 stages

Answer 32

Like the other just more diffuse 2 to 1 mandible
