periapical abscess การใช้

• 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.
• Furthermore, about 70 % of odontogenic infections occur as periapical inflammation, i . e . acute periapical periodontitis or a periapical abscess.
• However, certain patients with dentinogenesis imperfecta will suffer from multiple periapical abscesses apparently resulting from pulpal strangulation secondary to pulpal obliteration or from pulp exposure due to extensive coronal wear.
• In a periapical abscess, usually the origin is a bacterial infection that has accumulated in the soft, often dead, broken teeth or extensive periodontal disease ( or combinations of these factors ).
• The success rate of root canal treatment also depends on the degree of disease ( root canal therapy for irreversible pulpitis has a generally higher success rate than necrosis with periapical abscess ) and many other technical factors.
• A periodontal abscess occurs alongside a tooth, and is different from the more common periapical abscess, which represents the spread of infection from a dead tooth ( i . e . which has undergone pulpal necrosis ).
