This study is divided into 60 right anterior 10% underwent two weeks teeth mibaeksul every 2 hours a day evaluation teeth bleaching peroxide component and after teeth bleaching evaluate the re-coloring about coffee, cola, tea, artificial saliva group for 7 days to precipitate the solution were as follows. 1. After the tooth was of the hue variation mibaeksul Lab * L * values indicate a statistically significant difference in all groups (p<0.05), a * value of the control, green tea, black tea b * values are higher in the group coffee and tea It exhibited a difference (p<0.05). 2. hue variation according to mibaeksul teeth after treatment group (?E) has showed the most change in the tea group 3.83±0.94, control group 3.64±1.41, coffee 3.62±1.46, 3.60±0.67've found in green tea or order, was no statistically significant difference (p=0.941). 3. The tooth bleaching material after the color change of the coloring period, and a group * L * of the Lab color tone variation and b * values according to the eoteuna indicate a statistically significant difference at all treatment period (p<0.05), a * value is a statistical There was no significant difference (p>0.05). 4. shows a statistically significant difference on every period depending on the color tone variation (?E *) for a tooth bleaching material after staining group (p<0.05). 5. Re-colored period and ?Lab * each color variation according to treatment groups are ?L ?b * and * in accordance with the group exhibited a statistically significant difference between the coloring material is any period (p<0.05). More than 10% results showed a statistically significant change in tooth color using a peroxidase mibaeksul elements and color Lab * value change amount ?E all groups, the coloring material according to the period and the group is statistically in the L * and b * value It showed a significant difference. After the color tone change amount for the tooth bleaching material colored (?E *) also showed a difference in all groups. However, this period is precipitated in the drink was a slightly shorter period of 7 days study outside the mouth advances to be made it is a long-term follow-up study reflected the oral environment conditions and did not reflect self-cleaning effect of the saliva generated in the oral cavity It is believed.
