OBJECTIVE: This study was designed to examine the fluctuation tendency of the anterior teeth coloration during the period of growth puberty. METHODS: One hundred children with average age of 13.3 years, and 100 adolescents with average age of 23.4 years were divided into two groups. The upper left incisors were selected for color matching using computerized spectrophotometery system (Shade-eye, Shofu). The measurements depicting color properties, including hue, value and chroma were quantitatively analyzed. Statistical evaluation was conducted for the comparison of the color measurements between the two groups. RESULTS: The following trends were indicated during the period of growth puberty: (1)The hue of the coloration changed from redness into mixture of redness and grayness. (2)The magnitude of value of the coloration was in decline. (3)The intensity of chroma increased significantly. CONCLUSIONS: The teeth coloration fluctuates within the period spanning the initial and final stages of growth puberty, characterized by a decrease in hue and value and an increase in chroma.
