Comparative Study of Diagnostic Procedures for Halitosis: A Preliminary Approach

Renata de Oliveira CARTAXO, Wilton Wilney Nascimento PADILHA

Abstract


Objective: To compare the diagnosis of halitosis with an individual’s perception of halitosis through four different procedures.
Method: Forty male individuals were conveniently selected for this study. The volunteers were free of systemic or periodontal diseases, had no dental prostheses and were not receiving orthodontic treatment. Also, the volunteers were not using any antibiotic treatment or mouth rinses. Four methods were applied in addition to the individual’s auto-perception: organoleptic testing, oral malodor measurement, BANA test and measurement of both stimulated and resting whole saliva.
Results: There was a significant correlation between the sulfide monitor test and the organoleptic testing (Pearson’s test, p<0.01). There was also a positive association between the BANA and sulfide monitor tests (Fisher’s exact test, p<0.01). Moreover, the results of the sulfide monitor test were lower after the removal of the tongue’s bacterial plaque (p<0.01). There was a significant relationship between the resting whole saliva rate and the sulfide monitor test (Chi-square test, p<0.01). However, there was no correlation between sulfide monitor levels and the individual’s auto-perception (Pearson’s test, p>0.01).
Conclusions: It is possible to conclude that: the individual’s auto-perception is not reliable for the diagnosis of halitosis; organoleptic testing evaluation is important for the clinical diagnosis of halitosis; the plaque at the tongue dorsum is related to the formation of volatile sulfuric compounds; the presence of BANA-positive bacteria is related to higher levels of volatile sulfuric compounds; the amount of resting whole saliva interferes with the levels of production of volatile sulfuric compounds.
