Periapical periodontitis or apical periodontitis [9] (AP) is an acute or chronic inflammatory lesion around the apex of a tooth root, most commonly caused by bacterial invasion of the pulp of the tooth. [10]
Vessels and nerves: :25. dental :26. periodontal :27. alveolar through channel In dental anatomy, the apical foramen , literally translated "small opening of the apex," is the tooth's natural opening, found at the root's very tip—that is, the root apex — whereby an artery, vein, and nerve enter the tooth and commingle with the tooth's ...
The bacteria gains access to the periapical region of the tooth through deeper infection of the pulp, traveling through the roots. The resulting pulpal necrosis causes proliferation of epithelial rests of Malassez which release toxins at the apex of the tooth. The body's inflammatory response will attack the source of the toxins, leading to ...
Causes of tooth pain. If your teeth hurt, it could be a dental problem, a general health problem completely unrelated to your mouth, or something else. Before you start to treat your tooth pain ...
Tooth #5, the upper right second premolar, after extraction. The two single-headed arrows point to the CEJ, which is the line separating the crown (in this case, heavily decayed) and the roots. The double headed arrow (bottom right) shows the extent of the abscess that surrounds the apex of the palatal root.
Non-dental sources of pain often cause multiple teeth to hurt and have an epicenter that is either above or below the jaws. For instance, cardiac pain (which can make the bottom teeth hurt) usually radiates up from the chest and neck, and sinusitis (which can make the back top teeth hurt) is worsened by bending over.
The double headed arrow (bottom right) shows the extent of the abscess that surrounds the apex of the palatal root. The pain is continuous and may be described as extreme, growing, sharp, shooting, or throbbing. Putting pressure or warmth on the tooth may induce extreme pain. The area may be sensitive to touch and possibly swollen as well.
Infiltration analgesia is deposition of an analgesic (pain-relieving) drug close to the apex of a tooth so that it can diffuse to reach the nerve entering the apical foramina. [1] It is the most routinely used in dental local treatment. [2]
