Saliva Hypernatrium: An Exploratory Scoping Review Report uri icon

abstract

  • Purpose: This scoping review explored the available peer-reviewed literature, plus medical/health information management records, case studies, expert opinions in the field of otolaryngology, and other relevant resources relating to the condition of idiopathic persistent and excessive salty tasting saliva, labelled by the authors as ‘Saliva Hypernatrium’. Method: An exploratory scoping review was conducted using the Arksey and O’Malley (2005) method to source key literature and other resources. Results: A total of 684 articles were initially identified using search terms derived from conditions relating to taste, salt and saliva. A total of 12 articles were found to be specifically relevant. Six key themes were discernible from the 12 articles which identified possible causes for salty saliva having no currently known medical cause. Discussion & Conclusion: The overall findings identified numerous medical conditions which may cause persistent and excessive salty taste abnormalities. Treatment options are also considered. It is recommended that the term ‘Saliva Hypernatrium’ is a more appropriate and specialist term to be utilised for individuals experiencing an idiopathic and continuously salty taste, rather than current conventional generic terms that are potentially misleading. It is also recommended that further research be conducted in this field.
