RESUMEN
50 root dentin sections were obtained from 25 extracted premolars and divided randomly into 5 groups of 10 samples each. Except group 1, all the other group specimens were demineralised by immersing in a demineralising solution for 96 hours at 370C. The specimens were then subjected to surface treatment with grape seed extract, silverdiamine fluoride and calcium sucrose orthophosphate complex according to the groups. The samples were stored in artificial saliva during the intervals and subjected to pH cycling and evaluated using SEM-EDAX and the results statistically compared. The tested remineralizing agents showed statistically significant increase in remineralization when compared to the demineralized group. Calcium sucrose orthophosphate showed the highest Ca/Pvalues followed by Silver diamine flouride and grape seed extract
RESUMEN
Focal nodular hyperplasia (FNH) is a benign condition of the liver often discovered incidentally on radiological investigation. Although FNH is a well-described lesion in the literature considerable diagnostic problems regarding this entity still remains. We report a case of multiple FNH in a 23-year-old male patient detected as an incidental finding in autopsy. On gross examination FNH was not suspected because of the multiple lesions and the lack of central scar which is characteristically described in FNH. The diagnosis was established on histopathology after examination of multiple sections of the lesions.
