Pulp necrosis is a clinical diagnostic category indicating the death of cells and tissues in the pulp chamber of a tooth with or without bacterial invasion. [1] It is often the result of many cases of dental trauma , caries and irreversible pulpitis .
Pulp necrosis usually occurs either as ischaemic necrosis (infarction) caused by disruption to the blood supply at the apical foramen or as an infection-related liquefactive necrosis following dental trauma (2). Signs of pulpal necrosis include [42] Persistent grey colour to tooth that does not fade; Radiographic signs of periapical ...
Initially, the cyst swells to a round hard protrusion, but later on the body resorbs some of the cyst wall, leaving a softer accumulation of fluid underneath the mucous membrane. [citation needed] Secondary [clarification needed] symptoms of periapical cysts include inflammation and infection of the pulp causing dental caries.
The pulp is still alive, but the introduction of bacteria into the pulp will not allow the pulp to heal and it will ultimately result in necrosis, or death, of the pulp tissue. [ 11 ] Symptoms associated with irreversible pulpitis may include dull aching, pain from hot or cold (though cold may actually provide relief) lingering pain after ...
Pulpitis is reversible when the pain is mild to moderate and lasts for a short time after a stimulus (for instance cold); or irreversible when the pain is severe, spontaneous, and lasts a long time after a stimulus. Left untreated, pulpitis may become irreversible, then progress to pulp necrosis (death of the pulp) and apical periodontitis ...
Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.
There are some serious signs that indicate you should get medical attention for your insect bite quickly, however, Kassouf says. That includes: Symptoms of an allergic reaction , like swelling in ...
External inflammatory root resorption may be caused by trauma to the root surface, due to damage to the periodontal ligament (PDL) and/or extended drying following tooth avulsion. Following trauma, dentinal tubules are exposed leading to communication with an infective or necrotic pulp.
