Imaging methods and techniques in dental practice

The purpose of this study is to provide a brief overview of commonly applied imaging methods and techniques used in dental practice. Knowing the different types of X-ray techniques is closely related not only to obtaining good results but also to achieving radiation safety for patients and X-ray technicians.X-rays have great diagnostic value in daily dental practice. They are not only a supplement to the clinical examination but also a valuable diagnostic tool for visualization of the maxillofacial structures. Imaging methods play a pivotal role in determining treatment planning and assessing follow-up results for various clinical issues concerning the oral cavity and adjacent tissues. As imaging technology continues to advance, there is an increasing demand for more precise imaging methods and diagnostic tools. In modern dental practice, both conventional intraoral radiographs and advanced three-dimensional imaging methods, such as cone beam computed tomography, have found their rightful place. The transition from analog to digital radiography has not only simplified and expedited the process but also improved image retrieval, storage, contrast, and brightness. Moreover, three-dimensional imaging has revolutionized the examination of complex craniofacial structures, making them more accessible for analysis and expediting the process of early and accurate diagnosis.This article specifically focuses on the current advances in imaging technologies and their distinct characteristics. It does not address the issues related to their application in various dental areas, which may serve as subjects for future discussions.

Pelvic pseudotumor following total hip arthroplasty. Case report

According to the literature, the development of metallosis after hip arthroplasty occurs in approximately 5% of patients. Metallic debris in the joint results in massive local and systemic release of cytokines. Excision of the pelvic pseudotumor, as well as revision surgery, is mandatory if there is evidence of osteolysis and loosening of the endoprosthesis. Imaging diagnostics, including magnetic resonance and computed tomography, are crucial for the preoperative planning of surgical intervention

Intraoperative sentinel lymph node mapping in laparoscopic operations for colorectal cancer

INTRODUCTION: Laparoscopic resections in colorectal cancer gain an increasing popularity. Sentinel lymph node mapping in colorectal cancer and its advantages in daily practice are still subject of discussion. In laparoscopic operations, the procedure has same technical difficulties, although provides definite advan­tages in staging and estimating the extent of lymph dissection.MATERIALS AND METHODS: We present techniques for intraoperative sentinel lymph nodes mapping in colorectal cancer and their detection with surgical gamma probe in laparoscopic resection, which are used in our clinic, and the initial results from them.RESULTS: The initial results show that sentinel lymph nodes mapping with radionuclides and their detec­tion with surgical gamma probe are technically feasible in laparoscopic resections for colorectal cancer. The method has additional possibilities for the surgeon for estimating of the lymph drainage and precise stag­ing in laparoscopic operation.CONCLUSION: Nevertheless the contradictory opinions for application of sentinel lymph nodes mapping in colorectal cancer, the method provides certain advantages in improving staging. In laparoscopic opera­tions, although having some difficulties, it could be used, as it offers additional facilitation for the surgeon in estimating the lymph drainage in condition of decreased tactile sensation.

Giant pelvic well-differentiated liposarcoma

Herein, we report a case of a giant well-differentiated liposarcoma located subgluteally and extending into the pelvis through the obturator foramen, nearby the urinary bladder and rectum without causing functional disturbances. The tumor was removed simultaneously with transgluteal posterior and anterior transabdominal approach. Six months postoperatively, no clinical and radiological evidence of recurrence was observed
