General MicrobiologyAmoebic dysentery, caused by the protozoan parasite Entamoeba histolytica, is characterized by the presence of ghost cells in the stool. Ghost cells are the remnants of red blood cells that have been phagocytosed by the amoeba. These cells are ingested and their cytoplasm is removed, leaving only the cell membrane, which gives them a "ghost-like" appearance under the microscope. This feature helps distinguish amoebic dysentery from bacillary dysentery, which is caused by bacteria such as Shigella species. Bacillary dysentery typically shows the presence of white blood cells (pus cells) and red blood cells in the stool, but not ghost cells.

EndodonticsThe most frequent failures of root canal treated cases are often due to
inadequate obturation. This can occur when the root canal filling material does
not completely fill the space or when it is not properly compacted, leaving gaps
where bacteria can persist and cause reinfection. Proper preparation and
sterilization are also crucial, but inadequate obturation is the most common
technical error leading to treatment failure.

Conservative DentistryThe upper limit of urinary mercury attributed to extensive amalgam restoration is typically considered to be 4 micrograms/g of creatinine. While the actual limit can vary based on the individual and the extent of amalgam fillings, a level of 4 micrograms/g of creatinine is commonly used as a benchmark for evaluating potential health concerns related to mercury exposure from dental amalgam.
