Periapical periodontitis; Other names: Apical periodontitis, periradicular periodontitis: Periapical dental radiograph showing chronic periapical periodontitis on the root of the left maxillary second premolar. Note large restoration present in the tooth, which will have undergone pulpal necrosis at some point before the development of this lesion.
The diagnosis of pulp necrosis can be based on the following observations: negative vitality, a periapical radiolucency, a grey tooth discoloration and even peri-apical lesions. [17] This altered translucency in the tooth is due to disruption and cutting off of the apical neurovascular blood supply.
When the disease process is of pulpal origin, the pulpal infection and necrosis may drain not only through the apical foramen, but also through an accessory canal, which may present radiographically as a periradicular or furcation radiolucency. This may further lead to furcal involvement through loss of clinical attachment and alveolar bone.
Commonly known as a dental cyst, the periapical cyst is the most common odontogenic cyst. ... the cyst is caused by pulpal necrosis secondary to dental caries or trauma.
Periapical granuloma, [1] also sometimes referred to as a radicular granuloma or apical granuloma, is an inflammation at the tip of a dead (nonvital) tooth. It is a lesion or mass that typically starts out as an epithelial lined cyst, and undergoes an inward curvature that results in inflammation of granulation tissue at the root tips of a dead tooth.
Dental abscess; Other names: Dentoalveolar abscess, periapical abscess, tooth abscess, root abscess: A decayed, broken down tooth, which has undergone pulpal necrosis.A periapical abscess (i.e. around the apex of the tooth root) has then formed and pus is draining into the mouth via an intraoral sinus ().
This has led to the popular belief that necrotizing gingivitis is contagious, but this is not the case. The main features of necrotizing gingivitis are painful, bleeding gums and ulceration and necrosis of the interdental papilla. There may also be intra-oral halitosis, cervical lymphadenitis (swollen lymph nodes in the neck) and malaise.
Periapical readiograph of lower right teeth, showing a large carious lesion in the distal of the lower right second molar. The same tooth also has an extensive periodontal defect. At this stage, without further information, it is difficult to tell which process has occurred first and lead to the death of the pulp.
