Purpose: The present study was performed to evaluate the effect of hydroxyapatite dental paste on tooth hypersensitivity compared to other materials. Materials and methods: In the general fluoride dental paste, strontium fluoride dental paste and hydroxyapatite dental paste, patient-performed VAS and VAS(ice test) were measured at baseline, 1weeks and 4weeks. Results: 1. In patient-performed VAS, there were significant differences reducing of tooth hypersensitivity between general fluoride toothpaste and hydroxyapatite toothpaste. 2. In operator-performed VAS(ice test), there were significant differences reducing of tooth hypersensitivity among each group, between general fluoride toothpaste and hydroxyapatite toothpaste and between general fluoride toothpaste and strontium fluoride toothpaste. Conclusion: In conclusion, hydroxyapatite toothpaste can be applied for control of tooth hypersensitivity.

To investigate major characteristics affecting the consumer acceptability of Cheonggukjang, the physicochemical characteristics and consumer perception of 16 Cheonggukjang samples (seven commercial samples and nine samples prepared in the laboratory) were analyzed. Overall, consumer acceptability of Cheonggukjang increased with higher contents of amino nitrogen and volatile basic nitrogen, as well as at lower moisture contents. Cheonggukjang samples with higher consumer acceptability showed higher purchase intent (%) and willingness to pay (won/200 gram package), implying consistency in consumer evaluation. Ideal characteristics of Cheonggukjang were lighter color, less water in the soup, stronger characteristic Cheonggukjang taste, sweetness and nutty taste, as well as less off odors, saltiness, and bitterness. The result of this study demonstrates the needs to improve sensory quality by considering the relatively low consumer acceptability of Cheonggukjang samples.

This purpose of this study was to develop a tea with small red bean which have been known to have effect regarding anti-obesity, fatigue recovery, edema recovery, blood circulation, etc. In order to provide baseline data for small red bean tea we investigated the general components, antioxidative effect and proanthocyanidin analysis in small red beans[Phaseolus angularis W.F. Wight.]. Physicochemical analysis(pH, sugar content, salinity, turbidity), color, anti oralmicrobial activity, content of saponin and sensory test of small red bean with different boiling time in 8 minutes(SR1), 16 minutes(SR2), 24 minutes(SR3), 32 minutes(SR4), 40 minutes(SR5) was also measured. It was shown that the crude fat, carbohydrate, moisture, crude protein, crude ash content of small red bean were 1.0%, 63.9%, 12.8%, 18.7%, 3.6%. DPPH free radical scavenging activity, the total phenolic compounds content and flavonoid content increased significantly (p<0.001). The results of analyzed proanthocyanidin was distinguished by characteristic UV-visible spectra with absorption maximum at 320 nm(t(R) 7.589 min). As the boiling time(8 minutes:SR1, 16 minutes:SR2, 24 minutes:SR3, 32 minutes:SR4, 40 minutes:SR5) of small red beans increaseds, the pH significantly decreased(p<0.001). The sugar content, salinity and turbidity significantly increased(p<0.001). Moreover, Hunter L, a and b values, crude saponin also increased(p<0.001). The results of analyzed activity against oral bacteria, S. mutans, S. sobrinus, P. intermedia and P. gingivalis showed a higher antibacterial activities than E. coli and S. aureus. MIC was measured that S. mutans, S. sobrinus, P. intermedia and P. gingivalis showed a lower MICs than E. coli and S. aureus. The results regarding sensory test measures, In case of color, refreshing taste and overall quality, SR3 had the highest preference overall among tested samples. In cases conceming odor and taste, SR5 had the highest preference and with regards to sweetness and saltyness, SR4 had the highest preference.

In this study, we analyzed flower tea activity against oral bacteria. Lagerstroemia indica, Paeonia suffruticosa and Hemerocallis fulva showed high extract yields. Bellis perennis, Punica granatum and Cercis chinensis showed the high rates of yield by ethanol extraction. Extract yield seemed to be related to the characteristics of the specimens rather than to the solvent. Streptococcus mutans, Streptococcus obrinus, Porphyromonas gingivalis and Prevotella intermedia were used to investigate extracts activity against bacteria; the former two cause dental caries and the latter two cause halitosis. Cornus officinalis, L. indica, P. granatum and P.s uffruticosa showed high antibacterial activities against S. mutans. In specimens extracted with ethanol, P. suffruticosa, Camellia sinensis, Camellia japonica L. and Rosa hybrida showed high antibacterial activities. L. indica, P. granatum and C. officinalis showed high antibacterial activities against S. sobrinus. C. officinalis, P. granatum, L. indica and P. suffruticosa showed high activities for specimens extracted with ethanol. The results show that the warm extracts of C. officinalis, L. indica and P. granatum may be effective to prevent dental caries. In particular, the ethanol-based extracts of C. officinalis, P. suffruticosa and C. sinensis were effective to prevent dental caries and thus may be highly marketable. Chrysanthemum zawadskii, R. hybrida, P. granatum, C. japonica L. and Zinnia elegans showed high antibacterial activity against P.gingivalis. R. hybrida showed the highest ethanol extract activity, followed by P. suffruticosa, P. granatum, C. japonica L. and L. indica. R. hybrida, P. granatum, C. morifolium and C. japonica showed high activity against Pr.intermedia in the order named. C. zawadskii, P. granatum, L. indica, C. japonica and A. princeps showed high ethanol extract activity. Thus, the warm extracts of R. hybrida, P. granatum and C. japonica may be helpful to reduce halitosis. In addition, the ethanol-based extracts of P. granatum, C. japonica and L. indica are expected to be highly marketable as mouthwashes.
