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.

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.

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.

Periapical cemental dysplasia with multiple lesions

International Journal of Oral and Maxillofacial Surgery, 1987
3 cases of periapical cemental dysplasia with multiple lesions in both maxilla and mandible are reported. All 3 patients are middle-aged females with an average age of 47 years; histological examination of excised tissue revealed that the lesions were composed of fibrous connective tissue and cementum-like hard tissue.

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 ...
