Methods of judging mouth odor

Abstract

convenient methods for judging mouth odor with the use of an artificial mouth odor prepared by a convenient method which load any burdens neither on the operator nor on he subjects. Saliva collected immediately after wake-up is cultured under anaerobic conditions and head space components of the thus cultured saliva are analyzed, or anaerobic bacteria contained in the collected saliva are counted.

What is claimed is:  
     
         1 . A method of judging mouth odor characterized by culturing saliva immediately after wake-up under anaerobic conditions and analyzing the head space components of the cultured saliva thus obtained.  
     
     
         2 . The method of judging mouth odor as claimed in  claim 1 , wherein cresol, indole or skatole in the head space components is detected.  
     
     
         3 . A method of judging mouth odor as claimed in  claim 1  or  2 , wherein the head space components are adsorbed by a solid phase microextraction unit and then analyzed.  
     
     
         4 . A method of judging mouth odor characterized by counting anaerobic bacteria contained in saliva immediately after wake-up.  
     
     
         5 . An artificial mouth odor characterized by comprising head space components of cultured saliva obtained by culturing saliva immediately after wake-up under anaerobic conditions.
