A periapical lesion, not always an inflammation. Periapical radiolucencies

Nederlands Tijdschrift Voor Tandheelkunde, 2022
A radiolucency, radiopacity or mixed lesion, identified on a radiograph is usually the result of an inflammation of endodontic origin. However, a periapical lesion is sometimes caused by primary bone pathology, predominantly manifesting at the apices of the teeth.

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.

Toll-like Receptor 2 Knockout Mice Showed Increased Periapical Lesion Size and Osteoclast Number

Journal of Endodontics, 2012
Introduction: The aim of this study was to characterize the formation and progression of experimentally induced periapical lesions in TLR2 knockout (TLR2 KO) mice.

Proliferative Activity In Periapical Lesions

Australian Endodontic Journal, 2003
ABSTRACTThe identification of proliferative activity in periapical lesions may be useful in discovering the biological behaviour of different cell types. Proliferant cell nuclear antigen (PCNA), Ki67, CD3 and p53 have been used for the evaluation of the proliferative ability of many lesions. In this study, 16 periapical granulomas and 8 radicular cysts

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 ...

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.

Innervation of the inflammatory periapical lesions

Oral Surgery, Oral Medicine, Oral Pathology, 1981
Abstract Specimens were taken from periapical lesions of ten cariously involved extracted teeth with radiolucencies. The lesions were examined with light and electron microscopes to determine the status of innervation. Nonmyelinated and myelinated nerve fibers were present, both intact and demyelinated, in severely inflamed tissue.

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.
