摘要

导言:纤维增强复合材料桩(FRCP)因其在牙冠大面积破坏的牙齿上具有多种优势而广受欢迎。适当的消毒对成功粘接这些柱子至关重要。清洁和消毒根管的常用溶液会对粘接强度(BS)产生不利影响。本研究旨在评估光动力疗法对纤维桩与根管牙本质粘接强度(BS)的影响。方法:研究对象为人类上颌犬齿。在牙颈线处拔除牙冠并进行根管治疗。制备纤维桩间隙后,根据光敏材料将牙齿分为五组:去离子水组、吲哚菁绿和 810 纳米激光组、亚甲基蓝和 660 纳米激光组、甲苯胺蓝和 635 纳米激光组、姜黄素和 LED 组。光动力疗法后粘接牙柱。通过横向切片制备颈部、中部和根尖样本。在万能试验机上测量了推出粘接强度(PBS)值。最后,使用方差分析和 Howell-Games 检验对数据进行统计分析。结果单因素方差分析显示各组之间没有显著差异(PP>0.005)。亚甲基蓝组(3.34±2.15)、吲哚菁绿组(2.59±3.16)和甲苯胺蓝组(2.45±1.73)的 BS 均低于对照组(PC 结论:与其他光敏材料不同,卷曲材料的 BS 值较低:与其他光敏材料不同,姜黄素不会对 BS 产生不利影响。

Effect of Photodynamic Therapy with Four Light-Sensitive Materials on the Bond Strength of Fiber Posts to Root Dentin.

Introduction: Fiber-reinforced composite posts (FRCP) have become popular due to their multiple advantages in teeth with extensive crown destruction. Proper disinfection is essential for the successful bonding of these posts. Commonly used solutions for cleaning and disinfecting the root canals adversely affect the bond strength (BS). Photodynamic therapy is an alternative method for irrigating the root canal and disinfecting the post space.This study was designed to evaluate the impact of photodynamic therapy on the BS of fiber posts to root canal dentin. Methods: Human maxillary canines were recruited for this study. The tooth crowns were removed at the cervical line and endodontically treated. After fiber post spaces were prepared, the teeth were assigned to five groups based on the light-sensitive material: deionized water, indocyanine green and 810-nm laser, methylene blue and 660-nm laser, toluidine blue and 635-nm laser, curcumin and LED. The posts were cemented after photodynamic therapy. Cervical, middle, and apical samples were prepared by transverse sectioning. Push-out bond strength (PBS) values were measured in a universal testing machine. Finally, the data underwent statistical analyses with ANOVA and Howell-Games tests. Results: One-way ANOVA revealed no significant differences between the groups (P<0.001). The Games-Howell test showed that curcumin (7.23±3.75) and the control group (5.92±4.04) had a similar BS (P>0.005). The BS was lower in the methylene blue (3.34±2.15), indocyanine green (2.59±3.16), and toluidine blue (2.45±1.73) groups than in the control group (P<0.005). Conclusion: Unlike other light-sensitive materials, curcumin did not adversely affect the BS.
