Endotoxic activity in periapical lesions

Oral Surgery, Oral Medicine, Oral Pathology, 1982
Thirty tissue samples were examined histologically and classified as being inflamed (apical granulomas) or noninflamed (scars or noninflamed cysts). The samples were then homogenized in pyrogen-free water and treated to remove interfering substances. The presence of endotoxin was then determined by means of the limulus assay; 75 percent of the inflamed

The diagnosis of a multilocular periapical lesion

Journal of Endodontics, 1987
The case presented illustrates the importance of complete diagnosis prior to endodontic therapy. The completion of endodontic therapy on a single tooth resulted in total healing of a multilocular lesion involving two root apices.

Epithelium and bacteria in periapical lesions

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2006
The purpose of this study was to evaluate 50 human periapical lesions for bacteria and epithelium in a case study in dental practice.Specimens were obtained from the extraction of 50 untreated teeth that had lesions attached to their apices. The specimens were histologically evaluated using serial sections.Bacteria were found in all teeth, colonizing ...

Anterior Stafne's Bone Cavity Mimicking a Periapical Lesion of Endodontic Origin: Report of Two Cases

Journal of Endodontics, 2009
INTRODUCTION: This report of 2 cases describes the diagnostic procedures used to identify 2 Stafne's bone cavities (SBC) found in unusually anterior locations in the mandible, both mimicking periapical lesions of endodontic origin.

Microorganisms in closed periapical lesions

International Endodontic Journal, 1998
The purpose of this study was to investigate the microorganisms of strictly selected closed periapical lesions associated with both refractory endodontic therapy and pulpal calcification. Definitive criteria were established that assured complete clinical isolation of the periapical lesion from the oral and periodontal environment.

Epithelial proliferation in periapical lesions

Oral Surgery, Oral Medicine, Oral Pathology, 1969
Abstract Various endodontic procedures were performed on seventy-two teeth which had no periapical pathosis prior to endodontic treatment. From 6 to 360 days later the periapical tissues of these teeth were examined histologically. In eighteen such tissues (26 per cent), proliferation of cell rests of Malassez had occurred.

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.
