Abstract
|
|
|
|
Actinomycetes is a type of normal inhabitants of the oral cavity and is an anaerobic bacteria mainly distributed on the root surface in contact with the gingival sulcus. A. israelii, a gram-positive bacterium, is normally present in carious teeth and calculus with the highest frequency. In the environment such as traumatic injury, apical infection, and pericoronitis that occurs around a partially impacted tooth, the nature changes to infectivity and causes an acute inflammatory response. For the treatment of actinomycosis, large doses of penicillin are administered for at least 10 days after surgical drainage and debridement. The apical lesions on radiographs can sometimes appear as malignant lesions, so differentiation is necessary and biopsy is essential. Therefore, in this classroom, actinomycosis was diagnosed and reported in the biopsy of the apical lesion of a tooth that had been extracted due to severe dental caries, and the literature review was conducted.
