  • Title: Oral malodor in beagles: association with indicators of periodontal disease.
    Author: Simone AJ, Logan EI, Livgren R, Suelzer M.
    Journal: J Clin Dent; 1997; 8(6):163-8. PubMed ID: 9586533.
    Abstract:
    The study of oral malodor continues to receive attention. Most bad breath is of oral origin and can be corrected with proper oral hygiene. Studies performed with saliva from people with periodontal disease and from healthy individuals showed that saliva from diseased patients produced a more objectionable odor faster than that of healthy people, and that the volatile sulfur components (VSC) produced may actually play a role in the etiology of periodontal disease. However, not all people or animals with bad breath have periodontal disease. The objectives of this study were to determine if a trained panel could discriminate between 10 dogs with clinically defined periodontal disease and those with relatively healthy periodontium. Second, this study attempted to establish a correlation between odor intensity and six clinical parameters of oral health. The judges were able to differentiate between the two groups of dogs based only on oral malodor (p < 0.02). There were strong associations of the intensity of oral malodor with oral health index scores. The correlations established between odor and gingivitis (r = 0.81) and between odor and furcation exposure (r = 0.88) were very high and statistically significant. Similarly, probing depth (r = 0.73), plaque (r = 0.07) and tooth mobility (r = 0.66) showed clear, positive relationships with oral malodor.
