目的比较5种比色板对天然前牙颜色的覆盖误差,以期为临床提供参考.方法用比色仪(Crystaleye)测量310颗天然前牙的颜色,并用配套软件对天然牙及内置5种比色板A(VITA Classical)、B(VITA 3D-Master)、C(Chromascop)、D(Shofu Vintage Halo NCC)和E(Noritake)的颜色进行分析,计算比色板与天然牙各部分颜色的色差,使用单因素方差分析和Tukey法比较各比色板对天然牙颜色覆盖误差的差异.结果牙颈部颜色覆盖误差比色板A(3.09 ±0.97)最大,比色板D(1.62±0.75)最小；牙中部颜色覆盖误差比色板B(1.65±0.64)和比色板D(1.52 ±0.74)显著小于比色板A(2.04 ±0.80)、C(2.04 ±0.90)、E(2.02 ±0.84) (P ＜0.05),比色板B、D间差异无统计学意义(P＞0.05)；牙切端颜色覆盖误差各比色板均小于2.00,比色板A(1.81 ±0.86)最大,比色板D(1.28±0.55)最小.结论比色板D在牙齿颈部、中部、切端三部分均能更好地覆盖天然牙的颜色.

Objective To compare the coverage errors (CE)of five different shade guides in anterio vital natural teeth of selected people.Methods Anterior vital natural teeth were measured with Crystaleye spectrophotometer,color coordinates of the teeth and five shade guides A (VITA Classical),B (VITA 3D-Master),C (Chromascop),D (Shofu Vintage Halo NCC) and E (Noritake)were analyzed with the supporting software.The CE of the five shade guide systems to natural teeth were evaluated in cervical,body and incisal regions,and difference in CE among shade guides was determined.Results In the cervical region,shade guide A had the maximal CE value (3.09 ±0.97) and shade guide D had the minimal CE value (1.62 ± 0.75).In the body region,CE of shade guide B (1.65 ± 0.64) and shade guide D (1.52 ± 0.74) were lower than those of shade guides A (2.04 ± 0.80),C (2.04 ± 0.90) and E (2.02 ± 0.84) (P ＜ 0.05).In the incisal part,all CE were below 2.00,and again shade guide A had the maximal CE value (1.81 ± 0.86) and shade guide D had the minimal CE value (1.28 ± 0.55).Conclusions Within the limitation of the study,shade guide D had better color coverage of natural teeth in cervical,body and incisal regions.
