Radiolucent Lesions, Dawn Gillespie, DEN 222 Oral Pathology, All of the…

- - - - ETIOLOGY
        accumulation of fluid or blood between the crown of an erupting tooth and the reduced enamel organ, due to trauma.
        METHOD OF TRANSMISSION
        N/A
        CHARACTERISTICS
        darker appearance and appear elevated. smooth bluish swelling (dome-like) on the crest of the alveolar ridge
        DENTAL IMPLICATIONS
        failure of the tooth to erupt
        TREATMENT/PROGNOSIS
        No treatment is necessary; however, on occasion, removal of the overlying tissue could facilitate a quicker eruption.
    - - ETIOLOGY
        odontogenic in development
        METHOD OF TRANSMISSION
        N/A
        CHARACTERISTICS
        usually only evident on radiographs, with no symptoms of pain or discomfort reported, well circumscribed, unilocular, and sometimes multilocular.
        DENTAL IMPLICATIONS
        Delayed tooth eruption
        TREATMENT/PROGNOSIS
        Complete removal of the cyst
  - - - ETIOLOGY
        dental lamina or its remnants
        METHOD OF TRANSMISSION
        N/A
        CHARACTERISTICS
        posterior mandibular region, large enough to displace teeth and extend through the cancellous bone into the oral cavity
        DENTAL IMPLICATIONS
        The association with nevoid BCC syndrome is especially important in a diagnosis, and the cysts have very aggressive behavior.
        TREATMENT/PROGNOSIS
        removal of the entire cyst
  - - - ETIOLOGY
        reduced enamel epithelium or odontogenic epithelium
        METHOD OF TRANSMISSION
        N/A
        CHARACTERISTICS
        masses within the oral tissues, almost always within the gingiva.unilocular or multilocular radiolucencies that exhibit clearly defined margins.
        DENTAL IMPLICATIONS
        Definitive diagnosis is important to rule out more aggressive lesions, and complete removal is necessary
        TREATMENT/PROGNOSIS
        Surgical excision
    - - ETIOLOGY
        Trapped epithelium
        METHOD OF TRANSMISSION
        N/A
        CHARACTERISTICS
        Cyst may be an inverted pear-shaped lesion, divergence of the tooth roots
        DENTAL IMPLICATIONS
        The vitality of the teeth involved, such as the lateral and cuspid, must be evaluated. Endodontic therapy should be administered when necessary.
        TREATMENT/PROGNOSIS
        Surgical removal
    - - ETIOLOGY
        odontogenic origins
        METHOD OF TRANSMISSION
        N/A
        CHARACTERISTICS
        swelling and expansion asymptomatic. pain/discomfort, infection, and paresthesia
        DENTAL IMPLICATIONS
        Follow-up is important since the recurrence rate is very high. Radiographic examinations are important in an early diagnosis of recurrence
        TREATMENT/PROGNOSIS
        enucleation, curettage, cystectomy, and excision
    - - ETIOLOGY
        epithelial remnants of the embryologic structure
        METHOD OF TRANSMISSION
        N/A
        CHARACTERISTICS
        pain, tenderness, and swelling, and drainage may be noted in the maxillary incisor region, well-circumscribed radiolucent lesion, which may have a sclerotic border
        DENTAL IMPLICATIONS
        The cyst is not radiographically diagnostic and must be removed and biopsied for definitive microscopic evaluation.
        TREATMENT/PROGNOSIS
        surgical removal
  - - - ETIOLOGY
        entrapment of the salivary gland tissue
        METHOD OF TRANSMISSION
        N/A
        CHARACTERISTICS
        Asymptomatic, radiolucency in the posterior mandible below the mandibular canal, sharply circumscribed, oval, radiolucent lesion with a sclerotic border
        DENTAL IMPLICATIONS
        usually diagnosed clinically by using radiographs; however, when the location is superior to the mandibular canal, a biopsy may be needed to rule out pathology.
        TREATMENT/PROGNOSIS
        noted and followed long term
- - - - Focal Cementoosseous Dysplasia
        
        most commonly occurs in the posterior mandible region. It is usually found in whites but may occur in other ethnicities as well
      - Florid Cementoosseous Dysplasia
        
        Florid cementoosseous dysplasia may cover a wide area of involvement in both jaws. Patients are more likely to report this form as producing symptoms such as a dull pain. Generally, this entity affects Blacks, Asians, and Whites.
        yellow bone-like material, and during surgical removal, it is difficult to separate the material from the bone
      - Periapical Cementoosseous Dysplasias
        
        ETIOLOGY
        unknown
        METHOD OF TRANSMISSION
        N/A
        CHARACTERISTICS
        asymptomatic, and the lesions are discovered on routine radiographs, asymptomatic, and the lesions are discovered on routine radiographs
        DENTAL IMPLICATIONS
        Without the proper diagnostic procedure, the tooth may be treated with a root canal when this is not necessary.
        TREATMENT/PROGNOSIS
        Periapical COD requires no treatment, and extraction or surgery is not required
