  • The Effect of Ceramic Thickness on the Surface Microhardness of Dual-cured and Light-cured Resin Cements. [Journal Article]
  • JCJ Contemp Dent Pract 2019 Apr 01; 20(4):466-470
  • Pishevar L, Ashtijoo Z, Khavvaji M
  • CONCLUSIONS: An increase in the thickness of ceramic could decrease the hardness of the resin cement. An overlying ceramic thickness of 3 mm and above was found to adversely affect the polymerization of the LC and DC resin cement and it was considered as the clinical threshold. In addition, using only the self-cured mode in the dual-cured resin cement was not sufficient for achieving the optimum surface microhardness. Clinical significant: Adequate polymerization of resin cement is essential for the optimal mechanical properties and clinical performance. It affects by increasing the thickness of ceramic restorations.
  • [Experimental study of platelet-rich plasma in treatment of Achilles tendinopathy in rabbits]. [Journal Article]
  • ZXZhongguo Xiu Fu Chong Jian Wai Ke Za Zhi 2019 Jul 15; 33(7):871-876

  • CONCLUSIONS: A rabbit model of Achilles tendinopathy can be reconstructed by type Ⅰ collagenase injection. PRP treatment can increase the Achilles tendon hardness and maximum breaking load, up-regulate the expression level of collagen type Ⅰ and Ⅲ, improve the structure of Achilles tendon collagen fiber, and promote the repair in rabbit Achilles tendinopathy model.
