概括

照射初始牙的修复表明,3MTM单键通用粘合剂 (SB) 的性能优于3M Adper单键2 (AS). 放射治疗后24小时,结合力最低,改善了6个月.

科学领域:

牙科材料科学牙科材料科学
辐射瘤学辐射瘤学
儿科牙科儿科牙科

背景情况:

对头癌的放射治疗可以在牙科修复中损害粘合剂粘合强度.
有限的数据存在于放射治疗对母牙粘合键强度的影响.

研究的目的:

为了评估两种粘合系统在接受放射治疗的母牙中的剪接强度.
为了确定在母牙进行放射治疗后进行牙科修复的最佳时间.

主要方法:

来自母牙的牙样本根据辐射暴露和恢复时间 (对照,辐射前,辐射后24小时,辐射后6个月) 被分为四组.
测试了两个粘合系统,3MTM单键通用粘合剂 (SB) 和3M Adper单键2 (AS).
样品接受了60 Gy的玛辐射剂量,随后进行了剪接强度测试.

主要成果:

与AS系统相比,SB粘合剂系统显示出明显更高的剪接强度 (p < 0.001).
在辐射后24小时 (G3) 进行的恢复显示出这两种粘合系统的粘合强度最低.
对SB的结合强度在对照组和6个月后辐射组之间没有显著差异,但在辐射后24小时显著下降.

结论:

照射母牙的牙修复最好在放射治疗后六个月进行,以获得最佳的结合强度.
3MTM单键通用粘合剂 (SB) 是比3M Adper单键 2 (AS) 更有效的选择,用于照射初级牙的修复.

Biological Effects of Radiation

Biological Effects of Radiation

All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...
