Purpose: This study was conducted to relate the histological diagnosis of chronic inflammatory periapical lesions with the radiographic images of these lesions.
Materials And Methods: A total of 70 biopsy specimens obtained during periapical surgery were stained with hematoxylin and eosin and examined under a microscope. Histological analysis established the diagnosis as granuloma, cyst, or scar tissue. The location of the lesion was recorded, as were the radiographic size (maximum and minimum diameter in mm and area in mm(2)) and the presence of radiopaque lamina around the lesion, using an image analyzing system.
Results: The distribution of the biopsy specimens was 65.7% granulomas, 25.7% scar tissue, and 8.6% cysts, 1 of which was a keratocyst. The largest lesions were cysts and epithelialized granulomas, with statistically significant differences. Radiopaque lamina was observed around 9 lesions; of these, only 2 were histologically diagnosed as cysts, with the rest as granulomas.
Conclusions: Most of the apical lesions were granulomas. Cysts had the largest radiotransparent images; however, in the 70 cases studied, neither the radiographic size nor the presence of associated radiopaque lamina alone was sufficient to determine the type of lesion. Histological analysis is required.

Morphological characteristics of the unique periodontal structure in dolphins.

Although toothed whales have dentition peculiar to mammals, little attention has been paid to the periodontal tissues that support these characteristic teeth. In this study, we clarified the anatomical characteristics of the periodontal tissue in several species of Delphinidae through three-dimensional observation using micro-computed tomography, histological observations using decalcified sections, and immunohistochemical analysis. The results indicated that the teeth and the periodontal tissues of dolphins are morphologically unique among mammals.

Complex odontoma is a benign odontogenic tumor composed of disorganized dental tissues, including enamel, dentin, cementum, and pulp. Unlike compound odontomas, which exhibit tooth-like structures, complex odontomas form a mass without anatomical organization. These tumors frequently present without symptoms and are typically identified inadvertently during standard dental imaging procedures.

Background: Among some of the known complications, breakage of epidural catheter, though is extremely rare, is a well-established entity. Visualization of retained catheter is difficult even with current radiological imaging techniques, and active surgical intervention might be necessary for removal of catheter fragment. We report such a case of breakage of an epidural catheter during its insertion which led to surgical intervention.

Background: Intraoperative localization of the correct spine level can be challenging when dealing with the thoracic spine; especially in morbidly obese patients and in mid-thoracic spine lesions. Different radiological reference markers techniques for dorsal surgery have been reported without a clear DAP (effective dose), localization and surgical time analysis.
Purpose: The aim of the study is to analyze the radiological reference markers technique in terms of localization time and radiation dose during surgery for dorsal lesions.
