Check: using the VITA Easyshade compact spectrophotometric colorimeter to check the color computer, is measured and recorded on the left to the right upper canine teeth in 6 teeth, the neck, the cut end of the a* value, b* value, L* value, according to the formula of tooth whitening toothpaste before and after the use of a E value. Asking subjects to brush your teeth, diet, no adverse reactions. And inform the need to stop the use of whitening toothpaste subjects, discontinue the use of whitening toothpaste, no whitening ingredients ordinary toothpaste. Finally the research of statistical data processing (SPSS17.0). Results: (1) VITA Easyshade compact photometric accuracy of computer colorimeter, repeatability of measurement results can be displayed, the data has high repeatability, reliable measurement results. (2) of all subjects using Shu Ke, the whitening toothpaste in the process, no adverse reactions occur, but there are 5 subjects in the use of whitening toothpaste at the beginning of Shu Ke 鍙�蹇嶈�愮殑鑸岀棝鎰，
