RadioVisiography in the Detection of Periapical Lesions

Journal of Endodontics, 2000
The periapical areas of 16 teeth from 6 human mandibular jaw specimens were randomly examined by 3 observers using conventional radiography with Kodak E-speed film and radiovisiography (with variable contrast and with fixed contrast). Each periapical area was examined preoperatively and after #2, #4, #6, and #8 sized bur periapical lesions were created

Prevalence of Periapical Lesions in Patients with Osteoporosis

Journal of Endodontics, 2021
Osteoporosis is a major systemic disease that can significantly deteriorate the quality of life of the affected individuals. It is more common in women, particularly after menopause. Osteoporosis may be associated with alterations in oral health. Treatment of osteoporotic patients mainly involves the administration of bisphosphonates (BPs).

Regulatory T-cells in Periapical Lesions

Journal of Dental Research, 2009
CD4 + CD25 hi Foxp3 + regulatory T-cells (Tregs) are of crucial importance in regulating the immune response, including the control of any defense against infection.

Decompression of large periapical cystic lesions

Journal of Endodontics, 1982
Abstract The removal of extensive periapical cystic lesions by surgical enucleation frequently causes postsurgical sequelae, such as devitalization of adjacent teeth, patient apprehension and discomfort, loss of bony support and, on occasion, paresthesia. An alternative approach is presented, whereby a tube is inserted into the cystic cavity.

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.

Overexpression of Cyclophilin A in Human Periapical Lesions

Journal of Endodontics, 2019
Cyclophilin A (CypA) is a cytosolic protein involved in multiple biological functions, such as inflammation, tissue remodeling, tumorigenesis, and vascular diseases. Human periapical lesions are induced by bacterial infections. However, the expression of CypA in human periapical lesions remains unclear.

Pressure exerted by odontic periapical lesions

Oral Surgery, Oral Medicine, Oral Pathology, 1971
Abstract Odontic periapical lesions can cause pain of varying intensities, and the degree of pain is determined by several factors. One of these—the pressure exerted by odontic lesions—can be measured directly. A study of mongrel dogs reveals that the pressure exerted by such lesions tends to follow the quantity of body fluid in the edematous animal ...

The Presence of Autophagy in Human Periapical Lesions

Journal of Endodontics, 2013
Autophagy, a lysosome- or endosome-mediated self-degradation process, participates in diverse neurodegenerative diseases, cancer, and inflammatory diseases associated with apoptosis. This study aims to identify the presence of autophagy in human periapical lesions and its possible colocalization with apoptosis.Forty-seven samples of human periapical ...
