背景/目的：牙周組織周圍的牙科樹脂黏固劑殘留是植體周圍炎的原因之一。嚴重病例可能導致植體鬆動或脫落。因此，本研究旨在對礦物三氧化物聚集體（MTA）進行改性，使其成為一種抗發炎的牙科植體冠黏固劑（ICC）。

材料與方法：本研究評估了去離子水溶液（Daq）、羥基磷灰石溶液（Haq）和氯化鈣溶液（Caq）對ICC凝固時間、抗壓強度、黏結強度和生物相容性的影響。以單因子變異數分析（ANOVA）檢定各實驗組間的差異（ P < 0.05）。

結果：表面微觀結構分析表明，添加Haq和Caq有助於ICC顆粒間的結合。表面元素分析表明，添加Haq增加了Ca離子含量。凝固時間結果表明，與Daq相比，Caq和Haq分別使最終凝固時間縮短了46.5%和34.7%（ P < 0.05）。 Caq的抗壓強度分別比Daq和Haq高35.1%和13.4%（ P < 0.05）。三種ICC組的黏接強度結果表明，樹脂黏接劑的效果相同（ P > 0.05）。生物相容性和清除活性測試表明，ICC優於樹脂黏接劑。

結論： ICC與Caq合併使用可縮短凝固時間、提高抗壓強度、增強生物相容性並降低發炎發生的可能性。因此，ICC與Caq聯合使用可作為牙科樹脂黏固劑的替代方案。

The Clinical Applications Of Platelet-Rich Plasma And Platelet-Rich Fibrin Combined With Photobiomodulation In Regenerative Dentistry: A Literature Review, Maryam Pourhajibagher, Rashin Bahrami, Abbas Bahador

Journal of Dental Sciences

Regenerative dentistry seeks to restore oral tissues through biologically driven therapies that stimulate endogenous healing. Among these, autologous platelet concentrates—namely platelet-rich plasma (PRP) and platelet-rich fibrin (PRF)—serve as reservoirs of growth factors such as platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-β), vascular endothelial growth factor (VEGF), and insulin-like growth factor (IGF), which promote angiogenesis, cell proliferation, and extracellular matrix formation. Complementing these biological mediators, photobiomodulation (PBM) represents a non-invasive light-based therapy that enhances mitochondrial activity, modulates inflammation, and accelerates tissue regeneration. Accumulating evidence suggests that combining PRP or PRF with PBM produces synergistic effects that surpass those achieved by …
