摘要：

目的探讨不同功率Er:YAG激光辐射牙釉质对粘接性能的影响。方法选择第一磨牙144颗,随机分为A、B、C三组,每组48颗。A、B、C三组每组再分6个亚组(n=8),用0、3、4、5、6、7 W等6种不同功率的激光照射处理过的釉质表面。A组以三点弯曲实验计算最大正应力及最大切应力;B组以Owens二液法测量表面能;C组以纳米压痕仪测量弹性模量及硬度。结果 A4组(5 W)最大正应力、最大切应力最大(P<0.05);A3(4 W)与A4(5 W)两组间无统计学差异(P>0.05);B3(4 W)组表面能值高(P<0.05);C4(5 W)组弹性模量数值最高(P<0.05),与C3(4 W)组无统计学差异(P>0.05);C3(4 W)硬度数值最高(P<0.05)。结论 4 W、20 Hz、200 mJ与5 W、20 Hz、250 mJ两个激光参数表现出了较好的粘接性能(总应力、表面能、弹性模量及硬度),可用于釉质表面处理增强粘接效果。

Abstract:

Objective To investigate the effect of different power of Er:YAG laser on bonding performance of tooth enamel. Methods One hundred and forty-four first molars were selected and randomly divided into three groups: A, B and C, with 48 in each group. Each group of A, B and C was divided into 6 subgroups (n=8), and the treated enamel surface was irradiated with 6 different power lasers, namely 0, 3, 4, 5, 6, and 7 W. Group A was calculated by three-point bending test for the large positive stress and the maximum shear stress; group B was measured by the Owens two-liquid method; group C was measured by the nano-indenter for the elastic modulus and hardness. Results The maximum normal stress and maximum shear stress of A4 (5 W) were the largest (P<0.05); there was no significant difference between A3 (4 W) and A4 (5 W) (P>0.05); B3 (4 W) had high surface energy value (P<0.05); the elastic modulus of C4 (5 W) was the highest (P<0.05), and there was no significant difference with C3 (4 W) (P>0.05); C3 (4 W) had the highest hardness value (P<0.05). Conclusion Two laser parameters of 4 W, 20 Hz, 200 mJ and 5 W, 20 Hz and 250 mJ show good bonding properties (total stress, table Energy, modulus of elasticity and hardness), and can be used to enhance the bonding effect of enamel surface treatment.
