Periapical periodontitis or apical periodontitis (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. It is a likely outcome of untreated dental caries (tooth decay), and in such cases it can be considered a sequela in the natural history of tooth decay, irreversible pulpitis and pulpal necrosis.

The lumen of the former is in continuity with the root canal lumen; the “true” cyst is dissociated from the root and may therefore be resistant to conventional root canal treatment (RCT) and need surgical extirpation. 2017-02-10 Periapical periodontitis Introduction.

2012). Periapical granulomas, periapical cyst and periapical abscess are enumerated as the bourgeois periapical lesions[1,2]. Periapical granuloma is a chronic inflammation located at the apex of a non vital tooth. It comprises of granulation and scar tissue permeated by diverse inflammatory cells (lymphocytes, plasma cells, macrophages, mast cells).

Acute Apical Periodontitis (symptomatic) Signs and symptoms: Exquisitely tender to touch, biting or percussion; Radiographically. There may be slight widening of the PDL; Chronic Apical Periodontitis (asymptomatic) There may not be any symptoms; The patient may also report that the tooth 'feels different' or is Objectives: Our aim was to compare periapical radiography and cone beam CT (CBCT) for assessment of the periapical bone defect 1 week and 12 months after root-end resection..

Although this inflammatory response typically causes pain and tenderness, it may be radiographically occult be-cause tissue destruction has not yet occurred (4). Neutrophils cause localized tissue destruction Apical periodontitis (AP) is an inflammatory condition that occurs around the root of a tooth. AP is a common disease, which increases in prevalence with age. This chapter describes the radiologicalpresentation of healthy and diseased periapical tissues at diagnosis and follow‐up of treatment.

Similarly, MMP-2 activity, when detected it was exclusively in diseased samples. Additional bands of estimated molecular weights of 60 and 48 kDa were observed. CONCLUSIONS: MMP-9 and -2 are highly increased in GCF from teeth with periapical lesions. These gelatinases could represent useful markers in monitoring chronic apical periodontitis in GCF. Course Dental Radiology and Radiographic Interpretation. 0 out of 48 steps completed 0%.

Reliabilities tested by Cohen's Kappa Coefficient and Recognition of dental disease by the interpreting radiologist has the potential to alter the course of patient care, such as when periapical disease is identified as the cause of sinusitis or pericoronitis is identified as the cause of deep neck infection. Furthermore, incidental recognition of carious lesions in both children and adults who are undergoing CT for other reasons may alert the patient and care team of the need for a dental consultation. Main indications. The main clinical indications for periapical radiography include: • Detection of apical infection/inflammation.
