Halitosis (bad breath) can be a cause of anxiety, depression and psychosocial stress, with pathological changes in the oral microbiota playing an important role in its development. Despite its prevalence, studies on the microbiology of halitosis are rare in Nigeria. This study determines the presence of five putative periodontal pathogens viz: Actinobacillus actinomycetemcomitans, Fusobacterium nucleatum, Porphyromonas gingivalis, Prevotella intermedia and Treponema denticola on the tongue dorsa of halitosis and non-halitosis patients using a 16S rDNA-directed polymerase chain reaction assay. Furthermore, an association of these bacteria with oral malodour [as assessed by volatile sulphur compounds (VSC) measurements] with a portable sulphide monitor, the Halimeter (Interscan Corp, Chatsworth, California), was performed.
