Then organoleptic test was performed for all patients. The ones whose organoleptic test scores was equal or greater than 2 were considered with halitosis. Descriptive statistics and statistical tests, chi-square, Mann-Whitney, and logistic regression modeling were used and data analysis was performed using SPSS 21.
Results: Out of 225 samples enrolled, 151 (67.1%) patients were suffering from halitosis. Tongue coating (p <0.0001), pericoronitis (p = 0.023) and tonsillitis (p = 0.025) had significant relationship with halitosis but decay and periodontal disease didn’t have.
