Aim of the study The aim is to detect the halitosis grade in the exhaled breath using two distinct techniques and to compare the readings with different clinical indices to find out the best method of halitosis grading. Materials & methods A total of 30 patients with chronic periodontitis having Oral malodor were included in the study. The subjective assessment of the exhaled breath(Halitosis grading) was done by 2 different methods using:Organoleptic(sniff test) method and a handheld portable Tanita FitscanSulfide monitor. The following parameters were assessed probing depth, gingival bleeding index, and plaque index. Statistical analysis The descriptive data that included mean, standard deviation (SD), and percentage frequency were estimated for each category of halitosis grading. For all tests, a P < 0.05 was found to be statistically significant. Results The median value of halitosis grading as obtained by Tanita FitScan was 3.0 (95% confidence interval as 2 and 4) which was then compared with clinical indices (PI, GI, and PD) and the results were found to bestatistically significant (P < 0.05) in both the groups with Tanita scoring assessment being percentage increase compared to organoleptic scoring.
