A dental x-ray is an used for checking teeth. During the inspection process, patient will receive dose resulting from function of formation x-rays. To know magnitude dose, radiation measurement tool required, and any instances hospital do not have it. see a was needed. In many cases, did it, so had to borrow instruments measure radiation. With these problems, purpose this research value exposed...

Dental X-ray image segmentation (DXIS) is an necessary process in Practical dentistry for diagnosis of periodontitis diseases from an X ray image. Thus, DXIS is one of the most important and necessary steps to analyse dental images. It helps to get worthy information for medical diagnosis support systems and other recognition tools. DXIS helps to get high accuracy of segmentation. In this paper...

PURPOSE Hand-held dental x-ray system is a self contained x-ray machine designed to perform intraoral radiography with one or two hands. The issue about its usage as general dental radiography is still in dispute. The aim of the present study was to assess the relationship between the amount of battery charge and the tube voltage in different hand-held dental x-ray systems. MATERIALS AND METH...

Teeth have been recognized as providing a useful long-term record of lead (Pb2+) uptake. However, information regarding the effects of lead on dental pulp tissue cells that foster dentinogenesis is scarce. This study investigated the effects of lead on dental pulp tissue using human dental pulp fibroblasts in vitro. Dental pulp cells from the teeth of young patients (aged 17-24 years) were cult...

A 40-year-old female dental technician visited our hospital for the investigation of a chest X-ray abnormality. Chest computed tomography demonstrated centrilobular nodules and lung volume reduction, and her serum KL-6 level was elevated. A histological analysis of the specimens obtained on a surgical lung biopsy showed peribronchiolar fibrosis with pigmented macrophages and cholesterol clefts....

Purpose Dual-energy X-ray imaging is widely used today in various areas of medicine and in other applications. However, no similar technique exists for dental applications. In this study, we propose a dual-energy technique for dental diagnoses based on voltage-switching. Materials and Methods The method presented in this study allowed different groups of materials to be classified based on at...
