초록

This study surveyed salivary flow rate, salivary viscosity, and salivary buffering capacity in order to intensively analyze salivary factors among factors of occurrence in dental caries for finding mutually different factors that function in occurrence of dental caries depending on each individual. Even the acid body within dental plaque has great influence upon dental caries. Thus, the comparative analysis was carried out by surveying the hydrogen ion concentration in dental plaque. The following results were obtained in this study. 1. The average decayed teeth in the survey subjects stood at 1.67 piece. The extracted teeth caused by dental caries stood at 0.47 piece. The filled teeth were indicated to be 6.31 pieces. Accordingly, the average permanent dental caries experience teeth were surveyed to be 8.44 pieces. 2. The results according to dental caries activity test method were indicated to be 12.56±4.15ml for the average stimulated salivary flow rate, 3.89±1.83ml for non-stimulated salivary flow rate, 1.49±0.69 for salivary viscosity, and 8.51±2.44 for salivary buffering capacity. The hydrogen ion concentration test in dental plaque was indicated to be 5.62±0.50 for before brushing teeth, 5.23±0.58 for 5 minutes after brushing teeth, 5.25±0.56 for 10 minutes after brushing teeth, 5.29±0.62 for 15 minutes after brushing teeth, 5.34±0.58 for 20 minutes after brushing teeth, 5.40±0.53 for 25 minutes after brushing teeth, and 5.61±0.59 for 30 minutes after brushing teeth. 3. Stimulated salivary and non-stimulated salivary flow rate,salivary viscosity, and salivary buffering capacity were indicated to be higher in group with non-caries than group with caries. However, it was statistically insignificant. The hydrogen ion concentration in dental plaque showed wholly statistical significant in the relationship with people with dental caries under progression. However, people without dental caries were indicated to be higher than people with dental caries. 4. As for correlation between caries activity test methods, the stimulated salivary flow rate had significantly positive correlation with non-stimulated salivary flow rate(p<0.001). Non-stimulated salivary flow rate showed negative correlation with salivary buffering capacity(p<0.01).
The hydrogen ion concentration test in dental plaque showed positive correlation according to the passage of time after brushing teeth. However, there was no significant correlation with salivary viscosity and salivary buffering capacity(p>0.05).
