A Study of Measurement of Halitosis with Oral/Breath Gas Detector B/B Checker™

Abstract

To evaluate a new device using burnable gas for the detection of oral malodor, 50 periodontitis patients and 20 healthy cohorts were enrolled, and the relationship between the oral malodor and progression of periodontitis was investigated. The following results were obtained: 1. Measured values of the burnable gas were 31.4±13.4 in the periodontitis group and 8.1±1.7 in the healthy cohorts. The periodontitis group showed significantly higher values than the healthy cohorts group, which suggests that a correlation exists between periodontitis and malodor. 2. In the periodontitis patients group, the measured value in pre-brushing was 30.8±16.6 and that in post-brushing was 26.5±13.3. The measured values reduced significantly after brushing, which suggests some association between plaque level and malodor. 3. There was no correlation between the measured values and the ratio of existing deep periodontal pockets greater than 4mm, which suggests that a factor affected the measured values other than the existing periodontal pockets. 4. The measurement of burnable gas was found to be an easy and effective method for the detection of mouth malodor.
