A Study on the Relationship between Halitosis Developments and Oral Environmental

The purpose of this study was to analysis know the important oral environmental factors which affect halitosis components of the adult in order to provide basic data for halitosis prevention and establish a device to eliminate halitosis efficiently. The 97 adults who visited at the Dental Clinic in Metropolis (M=68, F=30) participated in this study that performed from March in 2009 to in 2010. The obtained results through items as caries status, periodontal status, salivary flow, the viscosity, pH, Snyder test, plaque deposit, tongue plaque and halitosis check were as followings. The average shame of halitosis components appeared at hydrogen sulfide 36.71 ppb methyl mercaptan 31.46ppb dimethyl sulfide 54.33 ppb and Ammonia 22.60 ppm. The normality and the detection comparative result dimethyl sulfide above reverse appeared highly at 46.9%, ammonia appeared highly at 52%. According to the Hydrogen sulfide level was a high relationship among age, CPI, tongue coat status, DMFT index which were statistically significant (p<0.05). According to the quantity of hydrogen sulfide level there was relationship where tongue coat status Saliva flow rate considers statistically(p<0.05). The quantity of methyl mercaptan level there was relationship where Dimethyl sulfide level, tongue coat status, Saliva flow rate considers statistically(p<0.05). The quantity of Dimethyl sulfide level there was relationship where Hydrogen sulfide level, ammonia level, tongue coat status, Saliva pH and Saliva flow rate considers statistically(p<0.05). Ammonia level there was relationship where Methyl mercaptan level, CPI, and Saliva flow rate considers statistically(p<0.05).

구취발생과 구강환경의 연관성에 관한 연구

본 연구는 구취의 원인을 분류하고, 각 성분들에 영향을 미치는 구강환경 요인들과 어떤 관련성이 있는지를 조사하여 구취환자 개개인의 구강건강을 증진시키고 구취관련의 올바른 보건교육에 활용하고자 실시하였으며, 2009년 3월 1일부터 2010년 3월 1일까지 1년간 대도시 소재 치과병원 외래환자 98명의 자료를 최종분석에 이용한 결과 다음과 같은 결론을 얻었다. 1. 구취의 각 성분인 Hydrogen sulfide, Methyl mercaptan, Dimethyl sulfide 및 Ammonia의 평균 수치는 Hydrogen sulfide 36.71 ppb, Methyl mercaptan은 31.46 ppb, Dimethyl sulfide는 54.33 ppb, Ammonia는 22.60 ppm로 나타났고, 정상과 역치 이상의 검출비교 결과 Dimethyl sulfide는 46.9%가 역치 이상으로 검출되었고, Ammonia는 연구대상자 중 52%가 역치 이상으로 검출되어 가장 높게 나타났다. 2. Hydrogen sulfide 성분의 양에 따라 Dimethyl sulfide 성분의 양, 설태의 양과 타액 분비율이 통계적으로 유의한 관계가 있는 것으로 나타났다(p<0.05). 3. Methyl mercaptan 성분의 양은 Dimethyl sulfide의 성분과 설태량, 타액 분비율과 통계적으로 유의한 관계가 있었다(p<0.05). 4. Dimethyl sulfide성분의 양은 Hydrogen sulfide성분, Ammonia성분과 관련이 있었으며, 설태의 양, 타액분비율, 타액내 수소이온농도지수와도 관계가 있었다(p<0.05). 5. Ammonia성분은 Methyl mercaptan성분과 Dimethyl sulfide성분, 치주필요지수(CPI), 타액 분비율이 통계적으로 유의한 관계가 있었다(p<0.05).
