What does periapical lucency mean?
Periapical lucencies are often seen incidentally at head and neck imaging studies performed for indications not related to the teeth. These lesions are, however, occasionally manifestations of diseases that have a wide range of effects and may at times represent the source of symptoms that prompted the study.
What is a periodontal lucency?
Myriad non-odontogenic lesions, both benign and malignant, may be seen as a lucency around the tooth root that mimics a periapical lucency due to apical periodontal or pulpal disease. These conditions include fissural cysts, cemento-osseous dysplasias, giant cell granulomata, and simple bone cysts.
How can you tell the difference between a cyst and a granuloma?
Nevertheless, histopathologic examination is the only reliable method for distinguishing between these lesions. Whereas a periapical granuloma comrprises inflamed granulation tissue, a periapical cyst represents an epithelium-lined cavity with an inflamed fibrovascular connective tissue wall.
How can you tell the difference between apical periodontitis and periapical abscess?
It is caused when the infection extends through the apical foramen into the peri-radicular tissue. Periodontal Abscess is caused due to impaction of foreign body in the Gums leading to an abscess. It is different from Acute apical periodontitis as the infection is passed into the periodontium through the root canal.
How can you tell the difference between a cyst and a periapical abscess?
Difference between cyst and abscess. While a cyst is a sac enclosed by distinct abnormal cells, an abscess is a pus-filled infection in your body caused by, for example, bacteria or fungi. The main difference in symptoms is: a cyst grows slowly and isn’t usually painful, unless it becomes enlarged.
What causes a periapical lesion?
In contrast, the primary cause of periapical lesions is endodontic infection. PAMPs-triggered immune response induces proinflammatory cytokines and subsequent periapical pathosis, including chronic inflammation and bone destruction. The primary cause of periapical lesions does not overlap with metabolic disorders.
How are periapical lesions treated?
The treatment modalities for periapical lesions include non-surgical root canal treatment, periapical surgery, or tooth extraction. If non-surgical treatment is deemed ineffective or difficult, periapical surgery is the treatment of choice.
What causes a periapical granuloma?
It is a lesion or mass that typically starts out as an epithelial lined cyst, and undergoes an inward curvature that results in inflammation of granulation tissue at the root tips of a dead tooth. This is usually due to dental caries or a bacterial infection of the dental pulp.
What is dental periapical granuloma?
Periapical granuloma (plural: granulomas or granulomata) refers to a localized mass-like region of chronic granulation tissue in relation to teeth formed in response to infection. It often results in relation to chronic apical periodontitis.
How does a periapical granuloma appear?
A periapical granuloma is a relatively common lesion or growth that develops around the tip of a tooth’s root. It consists of a proliferating mass of granulation tissue (new tissue that forms on a wound) and bacteria that forms in response to dead tissue in the pulp chamber of the tooth.
