Radiolucent lesions - Coggle Diagram
Radiolucent lesions
Dentigerous cyst
Etiology: Arise from a cystic change in the dental follicle following crown formation when the follicle separates from the crown of the tooth
-
Characteristics: on radiographs the cyst as well circumscribed unilocular and sometimes multilobular. Since there are no calcified material desist appears completely radiolucent. This is is always associated with the crown of an impacted or on a uneruptured tooth
Dental implications: delayed to the Russian is a common theme. Has the potential to displace teeth and reabsorb roots
Treatment and prognosis: complete removal of the cyst is indicated, since the reoccurrence is high when this is not fully accomplished
Traumatic bone cyst
-
-
Characteristics: when questioning the patient with a radiolucent lesion the patient will often report previous trauma to the area in question. When the lesion is opened invariably only an empty cavity is found although it can Occasionally be full of blood
Dental implications: the traumatic bone cyst may continue to expand and increase in size when not detected in the early stages the lesion must be drained to Begin healing
Treatment and prognosis: the usual treatment involves opening the cyst. Once the blood cavity is indeed the bone will repair itself over time
Ameloblastic fibroma
-
-
Characteristics: the histology of the fibroma is unusually and highly diagnostic. The patient usually experience is no pain with no swelling that make her radio graphically do you lesions can be unilocular or multi locular it is normally well-defined and usually associated with an on an uneruptured tooth
-
Treatment and prognosis: conservative excision is the treatment of Choice. Some recurring as Amelio blastic fibrosarcomas which have been reported in previously begnin cases
-
-
Osteomyelitis
-
Method of transmission: the acute form of Osteo my lightest may have several infectious organisms involved in the disease process
Characteristics: an acute Infection may not produce the destruction that the chronic form produces because it has not been present long enough to create bone damage. In the chronic form more evident patches of necrotic bone and diffuse radiolucent lesions are seen and the lesions appear mottled
Dental implications: the patient may have pain and lymphadenopathy. Addressing the calls of the osteomyelitis is a paramount the correct antibiotic is needed to treat the infection: therefore identification of the specific organism through laboratory test is crucial
Treatment and prognosis drainage and antibiotics are needed to treat the acute form of osteomyelitis the chronic form is more difficult to manage because of the necrosis surgery is indicated with antibiotic coverage
Ondontogenic myxoma
-
-
Characteristics: unilocular or multilocular and the radiolucencies may have a scalloped appearance these lesions have a step ladder or honeycombed appearance
Dental implications: in large dental follicles or the dental papilla of a developing tooth may be mistaken for the lesion upon microscopic examination
-
-
Erruption cyst
Etiology: Caused by the accumulation of fluid or blood between the crown of an irrupt Ing twos and the reduced enamel organ
-
-
Dental implications: the only dental implication is the failure of the two to Iraq therefore the cities may be opened to Hasten the event
Treatment and prognosis: no treatment is necessary however on occasion removal of the overlying tissue could facilitate a quicker irruption
-
Periapical granuloma
-
-
Characteristics: seen radio graphically as a round or oval a translucent lesion. The size of the lesion may vary from several millimeters to larger
Dental implications: vitality testing is crucial since the tooth will test non-vital when obvious radiographic evidence is a parent
Treatment and prognosis: extraction of the non-vital tooth or endodontic treatment is the usual procedure
Nasopalatine duct cyst
Etiology: A developmental sis this is arises from epithelial remnants of the embryolgic structure of the nasal Palentine ducts
-
Characteristics: when drainage occurs with the nasopalatine says the patient may complain of a foul salty taste the patient may also experience pain discomfort and burning
Dental implications: the cyst is not radio graphically diagnostic and must be removed and biopsied for definitive microscopic evaluation
-
Lateral periodontal cyst
-
-
Characteristics: the teeth associated with the lateral. Donto says our vital. When a multi locular cyst is present it is called a variant of the lateral para Donnell says. These sis have a grape like appearance
Dental implications: the cyst should be identified as a lateral periodontal cyst since it is necessary to rule out an inflammatory tight lesion or a more serious type of cyst or tumor
Treatment and prognosis: surgical excision and pathologic review our treatment of choice vitality testing is important in order to avoid unnecessary endo treatment
Ridiculous cyst
Etiology: Always associated with the root of a non-vital twos and the common calls are Caries, trauma such as fracture or injury of the tooth or periodontal disease
-
Characteristics: the radicular cyst cannot be differentiated from the periapical granuloma by a radiograph. A pop testing device is used as the diagnostic tool however a biopsy is needed to confirm a radicular cyst
-
Treatment and prognosis: treatment usually involves several options: removal by extraction, surgery with curettage and root canal therapy the prognosis is good with complete removal
Langerhans cell disease
-
-
Characteristics: this disease may involve one or more multiple bones in the body including the bones around the teeth contributing to “floating tease”. A key characteristic of Langerhans cell disease is premature loosening and exfoliation of teeth in children
Dental implications: lesions that occur. Apically can be confused with periapical cysts or granuloma’s tooth vitality would still be present
Treatment and prognosis the treatment depends upon the involvement of the disease in the age of the patient. The prognosis is more favorable when the disease states develop an older young adults
-
Globulomaxillary cyst
Etiology: Believes you represent a visual cyst that arose from the epithelium that was thought to be trapped When the globular portion of the median nasal process fused with the maxillary process
-
Characteristics: the location of the pear-shaped configuration of the globulomaxillary says give it a classic type of presentation
Dental implications: the vitality of the teeth involves such as the lateral and cause been must be evaluated. Endo therapy should be administered when necessary
-
Aneurysmal bone cyst
Etiology: considered a pseudo cyst in that it appears as a cyst but unlike the epithelium lined true cysts, the aneurysmal bone cyst does not have the epithelium lined lumen. This type assist arises from trauma
-
Characteristics: these cysts exhibit some key radiographic appearances as the scribd the lesion presents as expansile with thin peripheral bone that is blood filled
-
Treatment and prognosis: excision and curettage our treatment of choice when the lesion is removed completely the prognosis is good
Static bone cyst
-
-
-
Dental implications: the cyst is usually diagnosed clinically by using greater graphs however when the location is superior to the mandible canal a biopsy may be needed to rule out pathology
Treatment and prognosis: the Cyst is noted and followed long-term and if any changes occur they are noted any patients record
