Urine discoloration occurs in the intensive care unit (ICU) due to many causes such as medications, metabolic disorders, and infections. Propofol is advocated as one of the first line sedatives in the ICU, but it is not well known to the intensivists that propofol can induce urine color change. We experienced two cases of green urine after propofol infusion. Propofol should be warranted as the ...

introduction: the aim of this study was to compare the discoloration potential of calcium-enriched mixture (cem) cement, white mineral trioxide aggregate (wmta) and calcium hydroxide (ch), after placement in pulp chamber. methods and materials: access cavities were prepared in 40 intact maxillary central incisors. then, a 2×2 mm box was prepared on the middle third of the inner surface on the b...

re-establishing a patient’s lost dental esthetic appearance is one of the most important topics for contemporary dentistry. new treatment materials and methods have been coming on the scene, day by day, in order to achieve such an aim. most dentists prefer more conservative and aesthetic approaches, such as direct and indirect laminate veneer restorations, instead of full-ceramic crowns for ant...

Objective. Determination of the effect of dentin bonding agent (DBA) on the prevention of tooth discoloration produced by mineral trioxide aggregate (MTA). Methods. 50 teeth were endodontically treated and after removal of 3 mm of obturating materials were divided into five groups. In white MTA (WMTA) and grey MTA (GMTA) groups, these materials were placed in root canal below the orifice. In DB...

What determines tooth color, its shades and hues and its variations even in the same person? 2. Does tooth color result from the distribution of a pigment at variable concentrations in tooth structure? 3. Is color a consequence of the level of mineralization of tooth tissues, their t...
