Purpose: This study was conducted to find oral health and eating attributes relating to the maxillary anterior teeth color and examine the meaning.Methods: This study aims to prepare the basic data of the teeth color by measuring analyze mode using the color of the maxillary anterior teeth(maxillary central incisor, lateral incisor, canine) of the dental patients as the dental colorimeter. Also, This researcher explained the purpose of this study to dental patients and got agreement of 111 patients(50 men and 61 women). We conducted the survey from 2 March to 25 May, 2015. So the color of total 333 teeth was examined, and eating habit attributes and oral health behaviors were researched.Results: Lightness(L) was significantly high in female compared to male(12, p<0.05), the more often intake of red pepper paste decreased(11, 13) lightness. and the brightness of the 31-40 age group was significantly higher(12, p<0.05) than the group under the age of 20.Red chroma(a) was significantly low in over 50 age group compared to the group under the age of 20(12, p<0.05), and the red chroma(a) of the "received periodic scaling" group was significantly lower(13, p<0.01) than the other group.

This study has been implemented to check the effect of roughness on the color stability according to the surface treatment of artificial teeth. 20 units of 3 groups with the different surface treatment of artificial teeth have been precipitated in the soy sauce, the red pepper paste, the coffee and the cola, measure equipment was used for Shade-eye(Chroma Meter, Shofu, U.S.A). The value of L*, a*, b* using its average value after measuring 3 times per 1 point by selecting 3 points randomly out of central parts of teeth on a cycle of each 1 day, 1 week, 2 weeks, 3 weeks, 4 weeks after precipitation in terms of precipitated specimens. As a result of Multiple regression analysis, the value of ΔE* of artificial teeth according to the surface treatment showed the significant negative(-) effect in the Group 2(p<0.001) and the red pepper paste had the biggest effect on the color change of artificial teeth out of pollution source.■ keyword :|Color Stability|Surface Treatment|Roughness|Precipitation|
