Evans blue and gentian violet: Alternatives to methylene blue as a surgical marker dye

Methylene blue dye: an aid to endodontic surgery.

In dentistry, methylene blue dye (injection USP 1%; American Quinine Co., Inc. Shirley, NY) is mainly used for laboratory research. In endodontics, it is used most often in marginal leakage studies to stain and locate those areas of the root canal system not sealed by the obturating material (1). It is also used to treat methemoglobenemia due to prilocaine toxicity (2, 3). Methyleneblue dye is ...

Removal of methylene blue dye aqueous solution using photocatalysis

The nano sized TiO2 and ZnO are the most active photocatalysts.  Methylene blue was used as a reference molecule for the photocatalytic degradation. The TiO2 and ZnO can totally remove methylene blue dye. The effect of various process parameters like initial concentration, contact time, dose of catalyst and pH on the extent of removal of dye by photocatalysis in presence o...

Methylene Blue Prevents Post-Surgical Adhesion Formation in the Rabbit

Peritoneal adhesions are challenging in abdominal surgery. In spite of different kinds of treatments still no definitive and effective treatment is suggested. To determine the prevention effects of intraperitoneal (ip) methylene blue in post surgical adhesion formation 44 rabbits were randomly divided in two groups of equal number. Group I received an intra peritoneal injection of a 1% suspensi...
