A 23-year-old Malay female patient presented with a history of pain and swelling over right maxilla. Imaging showed well-defined unilocular radiolucency areas radiopacity in the The lesion was initially thought to be unicystic ameloblastoma. However, histopathology excised proved otherwise final diagnosis given as dentinogenic ghost cell tumour. clinical presentation case, subtypes DGCT, simila...

Mineral trioxide aggregate (MTA) is well known as an effective root canal filling material for endodontics therapy. Within MTA, bismuth oxide (Bi2O3) serving the radiopacifier still has biocompatibility concerns due to its mild cytotoxicity. In present study, we tried modify Bi2O3 by doping hafnium ions via sol-gel process and investigated effects of different ratios (Bi2-xHfxO3+x/2, x = 0–0.3)...

A laboratory-based study of the physical and performance characteristics of a new 0.25-mm-thin microangioscope was performed. The microangioscope tested was compatible with currently available microcatheters, but its tip was considerably stiff and of limited radiopacity. Poor image quality and difficult image interpretation were further drawbacks. Intensive efforts are directed at addressing cu...

The aim of this study was to compare and analyze the site-specific accuracy of mixture of lipiodol and methylene blue (MLM) (0.6 ml, 1:5) and pure methylene blue (0.5 ml) on the rabbit lungs. In this study, CT-guided percutaneous injection of MLM and methylene blue. Compare the staining degree by biopsy of lung tissue. Use 4 points system to evaluate the site-specific accuracy at 6h and 24 h af...

Data on vascular anatomy traditionally have been derived from time-consuming gross dissection and histology, which has prevented the assembly of large sample sizes. Vascular injection of radiopaque medium (angiography) is a rapid technique, but, as typically performed, it has limitations (e.g., superimposition and poor subsequent dissectibility). We present a novel angiographic technique compri...
