目的:分析探讨龈下菌斑对慢性牙周炎患者种植体周围边缘骨吸收的影响。方法:选取慢性牙周炎牙列缺损及牙周健康牙列缺损患者进行种植手术,观察两组在术前术后改良菌斑指数、改良龈沟出血指数和种植体周骨吸收情况并进行统计分析。结果:种植前观察组的龈下菌斑明显高于对照组(P0.05)。术前两组患者改良龈沟出血指数(modified sulcus bleeding index,m SBI)对比差异无统计学意义(P>0.05),而经过种植术后,两组患者组内比较m SBI均明显低于术前(P0.05),而术后两组种植体周围边缘骨吸收较术前均明显减少(P<0.05)。术后观察组近中和远中边缘骨吸收量明显降低,其中近中降低较对照组更明显(P<0.05)。结论:慢性牙周炎患者的龈下菌斑多于牙周健康者且影响种植体边缘骨的吸收,进行牙周基础治疗有助于种植体周围边缘骨的稳定。

Electromagnetic interference (EMI) shielding inhigh-frequency range, especially the rapidly growing terahertz(THz) frequency range, attracts increasing attention due tothe potential application of terahertz in 6G wirelesscommunication, and security inspection. However, traditionalconductive EMI films typically achieve high shieldingeffectiveness through strong reflection, which may causesecondary pollution to other devices. Here, a gradientstructure strategy was proposed to constructTi_(3)C_(2)Tx/hydroxypropyl methyl cellulose (HPMC) film, in whichthe content of Ti_(3)C_(2)Tx gradually increases along the thicknessdirection, resulting in different conductivity of the two surfaces(surface-M and surface-H) for the film. The obtained gradientfilmexhibits an EMI shielding efficiency of over 48.5 dB in theTHz range (0.2-1.6 THz) at a thickness of 40 μm. Especially,as the THz waves incident from the surface-H to the film, the absorption effectiveness reaches 48.2 dB (average absorbedpower loss up to 91.4%), and the reflection effectiveness is only 0.3 dB. In additions, the gradient-film also demonstrates ahigh absorption rate of 95.5% in the infrared band (2.5-16.7 μm). Moreover, the gradient-film exhibits an excellent tensilestress and Young’s modulus value of 173.1 MPa and 2.8 GPa, respectively. Therefore, the gradient-film proposed in thiswork, with excellent electromagnetic absorption in both THz and infrared band, provides a promising candidate for the nextgenerationEMI shielding applications.
