  • The purpose of this study was to evaluate the relationship between periodontal disease and halitosis, and to develop a detail clinical protocol for assessing halitosis in animals. We measured the periodontal disease parameters, the degree of halitosis using organoleptic scale method and the concentration of volatile sulfur compounds(VSC) using portable sulfide monitor($Halimeter^{TM}$). In this study, VSC levels by $Halimeter^{TM}$ were found to be significantly associated with periodontal disease parameters(plaque index, calculus index)(P<0.05). We also found that conscious sedation did not affect the measurement of VSC levels.

  • 본 연구는 구강관리행태와의 연관성과 설태지수, 치석, 스케일링 전후의 구강환경에 따른 구취변화를 알아보고자 대전광역시에 위치한 K대학교 치위생학과에 스케일링 실습을 위해 내방한 참여자 130명을 대상으로 설태지수와 구취를 조사하여 조사하였다. 모든 조사대상자에 대하여 설문조사, 설태지수와 치면세균막과 치석정도를 측정한 구강검사, 구취측정 등을 하였다. 그 결과 설태가 구취에 가장 큰 영향을 준다는 것을 확인할 수 있었고, 이러한 설태지수는 흡연과 혀 닦기와 관련이 높았다. 또한 구취는 잇솔질 횟수가 많을수록 낮은 수치를 보였고 비외과적 치료인 스케일링을 통해 구취감소의 효과가 나타났으며, 나이와 설태지수가 관련요인임을 확인하였다. 이에 적절한 구강관리를 실천하여 치태과 설태의 양을 줄이고 정기적인 스케일링을 받음으로써 구강건강증진은 물론 구취감소의 효과를 얻어야 할 것이다.

  • Bacterial byproducts and volatile sulfur compounds(VSC) have been found to be the leading intra-oral agents, specifically, the byproducts of gram negative anaerobic bacteria have been implicated as primary factors of halitosis in patients presenting with periodontal disease. The objective of this study was to determine the correlation between periodontal treatment and the subsequent reduction in the level of halitosis. Forty-three subjects presenting with periodontal disease were examined before periodontal treatment, one week after treatment, one month after treatment, and finally, two months after treatment, using a portable sulfide monitoring $Halimeter^{(R)}$ to measure the VSC concentrations at the prescribed intervals. The results of the study were as follows: 1. Significant decreases in the mean VSC concentration were observed at the one week, one month, and two month post-op intervals relative to the pre-op measurement. (p<0.05) 2. Significant decreases in the mean VSC concentration were observed in subjects after completion of flap operations. Significant decreases in the mean VSC concentration were observed at the one and two month post-flap operation measurement relative to the VSC concentration at one week (p<0.05), but no significant differences between the one month and two month VSC concentrations were found. (p<0.05) 3. Significant decreases in the mean VSC concentration were observed in subjects after completion of subgingival curettage (p<0,05). Significant decreases were found between the one week and one month measurements and between the one month and two month measurements, but significant differences were not observed between the one week and two month measurements. (p<0.05) The results of this study show significant decreases in VSC concentration in test subjects after periodontal treatment. It can be inferred from the results above, that periodontal disease is a significant contributing factor of halitosis, and that treatment of periodontal disease can been an effective means of reducing VSC concentration in patients presenting with halitosis concurrent with periodontal disease.

  • Objective : This study was performed in order to provide basic data for halitosis prevention and establish a device to efficiently eliminate halitosis and to analyze the factors that affect the halitosis. Methods : Oral examination on the Gingival index, CPITN, Tongue Plaque index, and OHI-S as well as halitosis measurement among 293 rural residents. Results : Gingival index was high at mild on female and at moderate on male(p=0.025). Sorting the result by age, mild was 54.1% in the 40s, and moderate was 49.5%, 42.0% and 70.0% each in the 50s, 60s, and the 70s(p=0.005). The need for dental plaque management was 100%. The need for scaling was high with 78.3%, 93.0%, 89.9%, and 90.0% each for the 40s, 50s, 60s, and 70s. The need for complex periodontal treatment was also high with 32.4%, 47.5%, 48.7% and 60.0%, each for the 40s, 50s, 60s, and 70s(p=0.050). The highest bad condition for OHI-S was 69.5%, and good being 18.9%, and very bad being 11.6%. For moderate tongue plaque index was 74.4% as the highest. As the level of education increased, the slight tongue plague was increased, but in contrast, the moderate and higher tongue plague index was decreased(p=0.010). OG under 50ppm was 61.1% on male and OG over 50ppm was 50.9% on female(p=0.041). In OG over 50ppm, CPITN was 52.1% and 41.9% in scaling and complex periodontal treatment group(p=0.018). OHI-S, in bad and very bad condition with OG, over 50ppm, was 48.7% and 46.9%(p=0.019). The higher tongue plague index showed significant amount of increase at OG and EG above 50ppm(p=0.006). $NH_3$, as the tongue plaque index increased, the wider range of distribution was shown(p=0.000). As for the multiple regression analysis result, there have been selected females and tongue plaque index as factors affecting OG. There have been selected age and tongue plaque index as factors affecting EG and there have been selected females as factors affecting on $NH_3$. Conclusions : With the aforementioned results in mind, the status of halitosis among rural residents is considered to bare a close relation with oral environments. we have to focus on correct tooth brushing methods and tongue brushing, with using tongue cleaner to remove fur of tongue plaque. Also, in order to analyze exactly the factors of individual halitosis, we need continuous and systematic study.

  • This study was carried out to apply chemical gas sensors for the identification of bad breath which is one of the important sensitive problem for the humans' daily life. Seven sensors, including five semiconductor sensors and two electrochemical sensors, were tested for the three panels three times in several conditions. The results showed that the reproducibility of sensors were generally good, and electrochemical sensors showed better reproducibility while semiconductor sensors showed better sensitivity. No rinsing before measurement showed relatively better results in terms of both sensitivity and reproducibility. Semiconductor gas sensors for hydrogen sulfide shows the highest sensitivity, and it was recommended to use the odor-free bag for the measurement of bad breath.

  • Oral malodor in companion animals is noticed by owners at first and it makes owners unpleasant. Therefore oral malodor affects the relationship between pet and owner. Oral malodor is produced by some putrefactive bacteria which putrefy proteins to volatile sulfur compounds (VSC) such as methyl mercaptan, hydrogen sulfide and dimethyl sulfide in the food remnants. And oral malodor is mostly consisted with these VSC. On oral examinations in dogs with oral malodor, it is common that plaque and calculus index were increased than normal dogs'. But organoleptic method is subjective to evaluate halitosis, in this study we measured VSC using organoleptic method and portable sulfide monitor to clarify the relationship between halitosis and periodontal disease in dogs with halitosis. And we found that plaque index and calculus index were significantly related with VSC (P<0.05, P<0.05) in measurement using Halimeter. However there was not significant relationship between gingivitis index and VSC. In conclusion, there was the significant, positive relationship between periodontal disease and halitosis.

  • Halitosis is defined as a nasty odor emanating through the mouth and is primarily related to the enhanced concentration of volatile sulfur compounds (VSCs). VSC measurements have been commonly used for experimental comparison and clinical diagnosis. As quantitative methods for comparative analyses of oral malodor, gas chromatography devices have been most commonly used to quickly and easily determine the concentration of several gas components of VSCs, which are agents primarily responsible for halitosis. The concentrations of VSCs fluctuate dynamically depending on contributing factors, including various oral/systemic conditions, intake of medicine and food/drink, oral hygiene, and even routine daily activities. Therefore, the exact analysis of VSCs requires the appropriate standardization of not only exact measurement techniques but also participant conditioning with scientific considerations. Thus, this paper describes the experimental standardizations commonly recommended in previous literature and their scientific background.
