What is the difference between a periapical and a periodontal abscess? What are the periodontal disease stages? How to diagnose apical periodontitis?

Acute periapical periodontitis. In some cases, apical periodontitis can develop if there is an infection in the pulp of the tooth or if the pulp has died (known as pulp necrosis). Injury or trauma to a tooth can also potentially cause apical periodontitis. However the periapical tissue has the ability to heal if the cause of inflammation is removed.

Periapical periodontitis can be divided into acute and chronic apical periodontitis. Periapical disease is the result of interaction between bacteria (or their products) and the host defences. Both the non-specific and specific branches of host defences are recruited to defend against the threat of invasion of the body by bacteria. Asymptomatic Apical Periodontitis is inlammation and destruction of the apical periodontium that is of pulpal origin.

The most common type of dental abscess is a periapical abscess, and the second most common is a periodontal abscess.

In a periapical abscess, usually the origin is a bacterial infection that has accumulated in the soft, often dea pulp of the tooth. This review compared healing rates for single- versus multiple-visit root canal treatment for apical periodontitis. The authors concluded that there was a lack of evidence of a difference between single and multiple visits.

The presence of inflammation makes it tender when tapping or chewing on it. Slowly applied pressure may not be as painful. The keywords used for search were pathogenesis of apical periodontitis cytokines, periapical granuloma cytokines, inflammatory infiltrate apical periodontitis.

Chapter Apical periodontitis Zvi Metzger, Itzhak Abramovitz and Gunnar Bergenholtz Introduction Apical periodontitis is an inflammatory lesion in the periodontal tissues that is caused mostly by bacterial elements derived from the infected root canal system of teeth (Core concept ). The tooth could have been treated endodontically previously or have a big hole. Chronic apical periodontitis is generally a non-painful condition in which the apical portion (i.e. the part around the tip) of a tooth’s root is chronically inflamed. The term chronic means the condition has been present for a significant length of time (at least several weeks, and sometimes much longer).

A key purpose of establishing a proper pulpal and periapical diagnosis is to determine appropriate clinical treatment. A simple, practical and universal classification system for endodontic diagnosis that uses terms related to clinical findings is essential. Pulpitis, trauma or endodontic treatment Pulpitis and pulp necrosis: If pulpitis is untreate bacteria ,bacterial toxins , or the products of inflammation will extend down to the root canal and through the apical foramina to cause periodontitis with time. Apical periodontitis ’ is a general term used to describe the periapical inflammatory process that occurs in response to the presence of micro‐organisms and other irritants within the root canal system of a tooth.

Radiological aspects of apical periodontits. Further, there are extraradicular factors – located within the inflamed periapical tissue – that can interfere with post‐treatment healing of apical periodontitis.

The causes of apical periodontitis persisting after root canal treatment have not been well characterized. Inflammation in the periapical area of the periodontal ligament is similar to that occurring elsewhere in the body.

It is often accompanied by resorption of bone, and occasionally the root apex, sufficient to be detected radiographically. Periapical granuloma (Fig 3), cyst (Fig 4), and abscess (Fig 5) represent a spectrum of the same pathologic process and are difficult to distinguish from one another radiographically. The shared radiographic features include a lucent halo surrounding the tooth root, often with caries of the.
