A radiographic survey of periapical jawbone lesions

Oral Surgery, Oral Medicine, Oral Pathology, 1986
A radiographic survey of the jawbone adjacent to the teeth revealed a high incidence of bone pathosis in 889 randomly chosen patients. Jaw lesions, nearly all inflammatory, were present in every second person. Bone-destructive inflammatory processes (rarefying osteitis) were the most frequently encountered lesions, occurring in both the maxilla and the

Interpretation of periapical lesions using RadioVisioGraphy

Journal of Endodontics, 1994
Density and gray-scale changes in radiographs are important visual features the clinician uses to evaluate changes in bone pattern. With the advent of a new direct digital radiology system, RadioVisioGraphy (RVG), the controlled adjustment of contrast is now possible.

Proinflammatory and immunoregulatory mechanisms in periapical lesions

Molecular Immunology, 2009
Proinflammatory and immunoregulatory cytokines are important for the pathogenesis of periapical lesions. However, little is known about how their functions are balanced and controlled at different phases of lesion development. The aim of this study was to examine the relationship between the production of Th1, Th2, Th17 and T regulatory cell (T reg ...

The preparation of periapical lesions for flow cytometry

International Endodontic Journal, 2000
Aim  To devise an optimal protocol and to analyse the leucocyte composition of periapical (PA) lesions by flow cytometry.Methodology PA lesions were mechanically agitated, with and without proteolysis. This was with either 0.2% collagenase alone, or in combination with 0.02% DNA‐ase in serial incubations until all tissue was digested.

Development of periapical lesions.

Swedish dental journal, 1993
The purpose of the present study was to follow the development of periapical lesions both radiographically and histologically in infected teeth with open and sealed root canals. The mandibular premolars from five adult monkeys were used in the experiment.

Conservative reduction of large periapical lesions

Oral Surgery, Oral Medicine, Oral Pathology, 1970
T he clinician is often confronted with the problem of treating an extensive periapical lesion which may be cystic as a result of pulpal pathosis. Surgical management by curettement and/or apical resection has usually been the accepted procedure for such lesions.

[Periapical surgery with histologic examination of the periapical lesion. A case report].

Schweizer Monatsschrift fur Zahnmedizin = Revue mensuelle suisse d'odonto-stomatologie = Rivista mensile svizzera di odontologia e stomatologia, 2009
Periapical surgery is required when periradicular pathosis associated with endodontically treated teeth cannot be resolved by nonsurgical root canal therapy (retreatment), or when retreatment was unsuccessful, not feasible or contraindicated. Endodontic failures can occur when irritants remain within the confines of the root canal, or when an ...

The radiographic detection of periapical lesions in dogs

Oral Surgery, Oral Medicine, Oral Pathology, 1984
The study investigated the correlation between the radiographic and histologic examinations of periapical lesions in dogs. The roots of four dogs were examined 3 months after root fillings had been placed and those of two dogs 1 year after placement of root fillings.

Periapical lesions and residual dental cysts

British Journal of Oral Surgery, 1970
DENTAL or radicular cysts commonly originate within periapical granulomas associated with non-vital teeth. The central cells of a proliferating clump of epithelium may undergo degeneration to form the nucleus of a cyst, or a cyst may arise from degeneration of a connective tissue core entrapped within a loop of proliferating epithelium (Fig. I, D).
