Acute periradicular periodontitis

What are the different types of periodontitis? Is periodontitis an infectious or an inflammatory disease? What is the difference between a periapical and a periodontal abscess?

What does periapical periodontitis mean? Periapical periodontitis (AP) is an acute or chronic inflammatory lesion around the apex of a tooth root which is usually caused by bacterial invasion of the pulp of the tooth.

The presence of inflammation makes it tender when tapping or chewing on it. Slowly applied pressure may not be as painful. Periapical inflammation is usually due to tooth infection which characteristically causes pain of tooth in its socket.

Yet, acute forms do occur and may develop during the expanding phase of the initial lesion. Lesions of symptom-atic apical periodontitis may also emerge as a result of a disturbed equilibrium between the host defense and the bacterial infection in an already established lesion. Periodontitis Asymptomatic Apical Periodontitis Inflammation and destruction of apical periodontium that is of pulpal origin, appears as an apical radiolucent area, and does not produce clinical symptoms.

The process is accompanied by clinical symptoms such as pain, tooth elevation, and tenderness to pressure on the tooth.

It must be pointed out that, except for the outcome, there is no clear distinction between aseptic and infectious inflammations. The acute (symptomatic) process may develop without previous chronic inflammation or may be the result of exacerbation of a previously chronic asymptomatic lesion. Acute periapical periodontitis , also termed acute apical periodontitis , acute periradicular periodontitis , or symptomatic periapical periodontitis. Chronic periapical periodontitis A periapical granuloma (also termed an apical granuloma or a radicular granuloma) is mass of chronically inflamed granulation tissue that forms at the apex of the root of a nonvital (dead) tooth. The term chronic means the condition has been present for a significant length of time (at least several weeks, and sometimes much longer).

Huang, DDS, MS DSc† Abstract Four clinical cases of immature teeth that developed periradicular periodontitis or abscess underwent a con-servative treatment approach, i. It occurs as a sequence of various insults to the dental pulp, including infection, physical and iatrogenic trauma, following endodontic treatment, the damaging effects of root canal filling materials. Acute apical ( periradicular ) periodontitis : is characterized by pain, commonly triggered by chewing or percussion. Acute periradicular periodontitis alone is not indicative of irreversible pulpitis. It indicates that apical tissues are irritate which may be associated with an otherwise vital pulp.

A patient complains of acute pain hours after the insertion of a restoration in a tooth with no preexisting periapical pathology. The radiograph will show A well circumscribed 3mm radiolucent lesion is present in the apical region of the mandibular second premolar. The tooth is vital and tender to percussion. It may or may not be associated with an apical radiolucent area.

Symptomatic apical periodontitis and acute apical abscess are common causes of dental pain and arise from an inflamed or necrotic dental pulp, or infection of the pulpless root canal system.

Though there are several causes for this disease but one of the major reasons is occulsal traumatism. Difference between acute periradicular periodontitis and acute periradicular abscess is that the former is confined to the involved tooth and the latter is more generalized and frequently presents with gross swelling in the affected periradicular tissues.

Phoenix abscess is an acute periradicular abscess superimposed on a preexisting chronic periradicular periodontitis. It is an acute exacerbation of a previously existing chronic lesion. It is a result of an increase in the virulence of the bacteria or decrease in the patient’s resistance. There usually is no lesion apparent radiographically in acute apical periodontitis.

However, histologically bone destruction has been noted. Both statements are true b. First statement is true, second is false. AAA), also known as acute periapical abscess, acute dentoalveolar abscess or acute periradicular abscess, is a highly symptomatic inflammatory response of the periapical connective tissues.

It originates when the pulpal tissues initiate an inflamma-tory response to trauma or caries and may eventually lead to pulpal necrosis. Acute inflammation of the periradicular tissues (such as in acute apical abscess, acute periradicular periodontitis , and so on) is characterized by a reduction in mechanical pain thresholds presumably because of peripheral (e.g., sensitization of nociceptors innervating the periodontal ligament) or central (e.g., central sensitization) mechanisms. Following the removal of a vital pulp, a root canal is medicated and sealed. The patient returns with symptomatic apical periodontitis ( acute periradicular periodontitis ). The most probable cause is A child has received a successful inferior alveolar nerve block using 1.
