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 college students in their twenties as the dental colorimeter. The maxillary anterior teeth of the subjects of study as 467 students (male 89, female 378) were measured from 14 November to 2 December, 2011, so the color of total 1,401 teeth was examined, and oral health and eating habit attributes were researched. The survey results were as follows. 1. The color of maxillary anterior teeth was changed from maxillary central incisor to maxillary canine, brightness (L*) was decreased 76.79±4.86 to 69.72±4.62, red chroma (a*) was increased 2.02±2.00 to 4.10±2.60, yellow chroma (b*) was increased 15.51±3.42 to 20.10±3.46. 2. Brightness (L*) was different according to sex (p＜ 0.001), major (p＜0.001), grade (p＜0.001), smoking (p＜0.001), oral health education (p＜0.01), daily brushing frequency (p＜0.001), brushing method (p＜0.05), oral hygiene devices (p＜0.001), and red chroma (a*) to major (p＜0.001), daily brushing frequency (p＜0.05), brushing time after meals (p＜0.01), oral hygiene devices (p＜0.01), and yellow chroma (b*) to brushing time after meals (p＜0.01), subjective tooth color (p＜0.001). 3. Brightness (L*) of eating habit attributes was different according to coke, candy (R2=0.053, p＜0.05). In conclusion, this study demonstrates that the color of maxillary anterior teeth has differences in brightness (L*), red chroma (a*), yellow chroma (b*) from each tooth, also these showed various tendency according to the oral health and eating habit attributes.
