The loads and locations of bacterial types associated with oral malodour on the tongue surface and gingival crevice were investigated in @entity1 and the @entity235 respectively. In the @entity1 study, samples were taken from 50 subjects with brushes at the dorsal anterior, dorsal middle, dorsal posterior, dorsal posterior to the circumvallate papillae (DPCP), lateral posterior and @entity4037 ( @entity4037 ) surfaces, and cultured appropriately. Malodour was assessed by trained judges. Mean volatile @entity599 compound (VSC) producing bacterial counts (colony forming units/brush * 10(5)) were found to be highest (88.94) and lowest (0.33) at the DPCP and @entity4037 sites respectively. Anaerobic, gram-negative and VSC counts at DPCP surfaces increased with malodour intensity, whereas aerobic and @entity20842 counts decreased. The prevalence and populations of the VSC producing Porphyromonas and @entity3288 species were determined in the dental plaque from 34 @entity235 . Porphyromonas gulae and @entity3288 were present in 68% and 44% of @entity235 , and 47% and 23% of plaque samples respectively. P. gulae and Prev. intermedia counts increased with plaque quantity (P < 0.05) and @entity2522 (P < 0.1). The close association observed between @entity235 periodontal disease and measurements of oral malodour is supported.
