Abstract
Objective:To study the color character of the anterior teeth of young people in Chinese Hans population�Methods:In total,1769 anterior teeth of 132 young people aging from 20 to 35 years old were collected�A digital colorimeter was used to measure the value of L*,a*,b* of the teeth,and the chromatism(△E) was calculated according to the formula△EL*a*b* =[(△L*)2 +(△a*)2 +(△b*)2]1/2�Data were analyzed with SPSS 19�0 software package for Student’ sttest and one⁃way ANOVA�Results:①The mean value of L*a*b* of anterior teeth was:cervical region:L*:70�96 ± 3�05, a*:4�19 ± 1�30,b*:1�10 ± 3�52;body region:L*:71�63 ± 3�21,a*:2�13 ± 1�30,b*:19�43 ± 3�99;incisal region:L*:68�08 ± 2�91,a*:1�25 ± 1�23,b*:15�89 ± 3�71�②There were statistically significant differences between the central inci⁃sors and the lateral incisors as well as the canines in terms of L*a*b*�Meanwhile the difference was also found among the L*a*b* value of cervical,body and incisal regions�③No difference was found between the teeth of same position on the left side and the right side in terms of L*,a*,b*value(P>0�05)�Respectively,difference was found between the maxillary and mandibular teeth�Conclusion:The difference among cervical,body and incisal regions,as well as the influence of teeth posi⁃ton,should be considered while doing shade match in clinic.关键词
