periapical การใช้

• Most infections spread through the apical foramen from the pulp to periapical tissue.
• Apical foramen is the opening of the radicular pulp into the periapical connective tissue.
• The radicular portion is continuous with the periapical tissues through the apical foramen or foramina.
• The only exception to this is in those rare cases of periapical lesions of Maxillary Sinus.
• It is also known as periapical cyst, apical periodontal cyst, root end cyst or dental cyst.
• In contrast to a periapical abscess, periodontal abscesses are usually associated with a vital ( living ) tooth.
• The most common type of dental abscess is a periapical abscess, and the second most common is a periodontal abscess.
• The lesion will sometimes present very subtle radiographic changes often detectable only by a technetium scan or with multiple periapical radiographs.
• Because periapical disease is almost inevitably preceded by pulp disease, The same end can be accomplished by extracting the involved tooth.
• When infections such as these occur elsewhere in the body, the refuge from which bacterial reinforcements can mobilize to the periapical lesion.
• The predominant mechanism of bone resorption in a periapical lesion, as in the rest of the body, is the performed by osteoclasts.
• If the crack propagates into the pulp, irreversible pulpitis, pulpal necrosis and periapical periodontitis may develop, with the respective associated symptoms.
• Furthermore, about 70 % of odontogenic infections occur as periapical inflammation, i . e . acute periapical periodontitis or a periapical abscess.
• Furthermore, about 70 % of odontogenic infections occur as periapical inflammation, i . e . acute periapical periodontitis or a periapical abscess.
• Furthermore, about 70 % of odontogenic infections occur as periapical inflammation, i . e . acute periapical periodontitis or a periapical abscess.
• Other methods like radiographs ( occipitomental, OPG and periapical views ) can also be used to confirm the presence of any oroantral fistulas.
• Infection of the periapical tissue will generally resolve with the treatment of the pulp, unless it has expanded to cellulitis or a radicular cyst.
• In the periapical lesion, mediators that are normally produced primarily only by osteoblasts are released by many other cells as well, overstimulating proosteoclasts.
• :: : : : : : : " The pathogenesis of focal diseases has been classically attributed to dental pulp pathologies and periapical infections.
• An alternative approach using bitewing screening with selected periapical views is suggested as a method of minimising radiation dose to the patient while maximizing diagnostic yield.
