구취발생에 관여하는 구강내부요인에 관한 연구

초록

This study was peformed in order to find out the relationship between the causing factors and the production of each gas of oral malodor, to contribute the oral malodor control at dental clinic as well as to establish the effective application of malodor control project for public oral health program. 127 patients from 20 to 40 years old who had been visited for preventive dental cares were participated for the study. Such items as caries status , periodontal status , salivary flow, viscosity, pH, Snyder test , plaque deposit and tongue plaque were checked through the oral examination in order to find out the contributing factors. Hydrogen sulfide, Methyl mercaptan, Di-methyl sulfide and Ammonia gas components were checked with Oral-Chroma and Attain, the oral malodor check units. Not only the corelation coefficiencies but also the multi-way variance analysis were calculated between each causing factor and each component of oral malodor gases to estimate the contributing factors of the oral malodor. 1. There was no relationship between the caries status and each component of the oral malodor such as sulfur compound or Ammonia , both in laboratory test and VAS test (p>0.05). It revealed negative relationship between Hydrogen sulfide and FT(r=-0.1904, p<0.05) as well as the VAS and FT (r=-0.210, p<0.05). So, it was estimated that the less oral malador was recognized when caries state changed to filled state in Hydrogen sulfide laboratory test or VAS test. 2. High relationship was showed between salivary flow and Hydrogen sulfide (r=-0.183, p=0.039), Methyl mercaptan(r=-0.234, p=0.008), Dimethyl sulfide(r=-0.234, p=0.008) and Ammonia(-0.361, p=0.001) gas(p<0.05). 3. There was a high relationship between M-PHP(Modified-Patient Hygiene Performance Index) and tong plaque, all kinds of sulfide(r=0.249, p=0.005), Ammonia gas component(r=0.232, p=0.009). 4. It was found that considerable relationship was appeared between the periodontal status and Ammonia gas (r=0.274, p=0.002), so, it should be needed to control Ammonia. Such dental cares as the prevention or early treatment of periodontal disease and the accelerating the salivary flow as well as reducing the amounts and activities of filament or spiral typed oral micro-organism were recommended for adults, not only for dental care program at the dental clinics but also for public health programs, in order to promote the oral health and quality of life for individual and community peoples.
