Objectives: Despite a rise of an interest in tooth whitening, diverse problems are being caused in case of hydrogen peroxide that is being used as a tooth bleaching agent. Thus, the aim was to examine tooth whitening effectiveness using natural products as a plan for supplementing this. Methods: As a result of having measured a tooth color through using VITA Easyshade V after having developed toothpaste with the application of extracts such as Citrus Peels, Mulberry (Morus alba L.) Root Bark, strawberry, and lemon, and then having used it for 10 weeks, they are as follows. Both upper and lower 6 anteriors mostly got brighter. Results: A statistically significant difference was shown especially in the right canine (p=0.015), in the right central incisor (p=0.007), and in the left central incisor (p<0.001). In consequence of having measured a color change, the tooth got brighter gradually in the higher extract content and in the lengthier use time. In case of canine, it got less bright compared to other teeth. In the outcome of evaluating sensuality, most of the questions were indicated to be high in case of using a whitening toothpaste for 10 weeks. But in what "there is no stickiness in the mouth, the stickiness was more felt in the use up to 5 weeks, but was improved in 10 weeks. Conclusions: The bleaching effectiveness was proved by developing a toothpaste with the application of natural extracts. A short-term effect cannot be seen like a whitening agent of using hydrogen peroxide. But there is a continuous effect in consideration of tooth-brushing more than 3 times a day.

One of the best way to prevent dental caries and periodontal disease is removing dental plaque. Toothbrushing is also one of the crucial ways to gel rid of dental plaque and improve dental hygiene. The purpose of th is study was to examine how many bacteria were attached to toothbrushes used by dental palque acidogenecity and related behaviors to toothbrush use. Subjects in this study were 30 college students in their twenties, on whom a survey was conducted to find out how they cleansed their toothbrushes, how long they cleaned toothbrushes after brushing, and how to keep them. And then dental palque acidogenecity by caries activity test was implemented and the number of bacteria attached to their toothbrushes was tested. The findings of the study were as follows : 1. Concerning correlations between dental palque acidogenecity and the number of remaining bacteria in the toothbrushes used by students, the number of bacteria was lower in the group of students with no caries activity than in the group with mild caries activity. 2. As for relations between the way of cleansing toothbrushes and the number of bacteria, there was no statistically significant gap between the group of students who wetted their toothbrushes with water and rubbed the heads of them and the group of students who just only wetted their toothbrushes with no further actions. 3. Regarding the relationship of toothbrush cleansing time to the number of bacteria, the number of bacteria was lower in the group of students who cleansed their toothbrushes for 15 seconds or more. 4. As to the influence of the number of toothbrush used by students, there was no significant difference between the group using just one toothbrush and the other group using two or more toothbrushes. 5. As for correlations between the way of keeping toothbrushes and the number of bacteria, no significant gap existed between the group thai kept their toothbrushes separately and the other that didn't.

Some investigators who have tried to achieve the highly smooth surface finish using electrochemical processes have reported that high current density produced lustrous surfaces while the opposite conditions produced a passive layer and had a tendency to produce a black surface. However, processing at a low current density may produce a non-lustrous surface but the improvement of dimensional accuracy of the surface is significant. The surface with pulse process was a bit more lustrous than with continuous current but the black passive layer still could be found at grooved surface. There are two ways to achieve highly smooth surface finish. One is brushing it with a brush the other is electrochemical machining (ECM) with high current. The former method is the most common polishing practice, but not only may the surface obtained differ from operator to operator, but precision smooth surface on micro grooves are difficult to obtain. The latter one recently has been used to produce a highly smooth surface after EDM process. However, the material removal rate in ECM with high current is relatively high. Hence the original shape of the micro grooves, which was formed by electrochemical micro-machining (EMM) process, may be destroyed. In this study, an electrochemical polishing process using pulse current is adopted as a possible alternative process when micro grooves formed by EMM process should be polished. Mirror-like micro grooves with lustrous and smooth surface can be produced electrochemically with pulse current because the voltage and current used can be lower than the case of continuous current. This study will discuss the accurate control of physical and electrical conditions so as to achieve mirror-like micro grooves with lustrous and smooth surface without destroying the original shape of micro grooves.
