title: Pictorial assessment of the delivery of oropharyngeal rinse versus oropharyngeal spray.
abstract: Oral rinses/gargles and oral sprays are frequently used in the management of oropharyngeal inflammation. This pictorial study, using methylene blue dye as a marker of the distribution of these topical preparations in the oropharynx, suggests that oral sprays are more effective in coating the oropharynx than oral rinses, whilst oral rinses are better at staining the oral cavity and base of tongue. The authors therefore suggest that oral rinses should be used to treat disease in the oral cavity and oral sprays should be used to treat ailments in the oropharynx.
