Objective: to evaluate the possible risk factors for increased scores on the organoleptic test. Material and methods: a hundred and twenty individuals were selected, from both genders (range 18 to 66 years old), with the following characteristics: 60 individuals with halitosis with or without associated periodontal diseases (the cases) and 60 individuals without halitosis with or without associated periodontal diseases (the controls). Smokers, individuals with systemic diseases, with pseudo-halitosis, edentulous, and individuals under xerogenic medication and antibiotic were excluded. The sample was submitted to the organoleptic test, conducted by 3 examiners. Complete agreement among the examiners was required for halitosis diagnosis. Periodontal diseases assessment and the presence of tongue coating were recorded during clinical examination, by only one examiner. Univariate logistic regressions were performed to select the independent variables that would be included in a multivariate model, considering halitosis as the dependent variable. The selected variables were included in a stepwise multivariate logistic regression analysis. Results: The statistical analysis showed that tongue coating was a significant predictor of halitosis (OR= 4.46; 95% CI 2.069 - 9.639; p=0.0001). No other variable was included in the model. Conclusion: Tongue coating is a significant predictor of halitosis and could be used as a clinical guideline for halitosis diagnosis.

Objective: To evaluate parameters such as age, gender, stimulated and non-stimulated saliva flow rate and the presence of tongue coating as risk indicators of periodontal alterations. Methods: 120 individuals from both genders (18 to 66 years) were divided into cases and controls. The cases included individuals with gingivitis (n=20); peridontitis (n=20); halitosis (n=20) and halitosis associated with gingivitis (n=20) and periodontitis (n=20). The control group was composed by healthy individuals (n=20). Smokers, individuals with systemic disease, with pseudo-halitosis, edentulous and individuals under antibiotic and xerogenic medication were excluded. The sample was submitted to the following sequence of exams: assessment of malodor (organoleptic test), stimulated and non-stimulated saliva flow rate measurement, clinical anamnesis, tongue coating presence analysis and periodontal evaluation through circumferential probing of 6 sites in all teeth. All exams were performed by only one dentist, except the organoleptic test that was performed by three calibrated examiners. A hundred percent of agreement among the examiners (kappa = 1) was necessary for a person to be considered with halitosis.

Results: A multivariate logistic regression showed that only age (p=0.0004), tongue coating presence (p=0.0211) and non-stimulated saliva flow rate (p=0.0087) can be considered risk indicators for the increase of the periodontal alterations among the evaluated parameters.

Conclusion: It could be concluded that age, non-stimulated saliva flow rate and the presence of tongue coating increases the chance of a person to present gingivitis and/or periodontitis.
