Dental cements containing sericin powder with cell biological properties show effect of wound healing

将不同浓度的丝胶蛋白粉加入市售的自粘性树脂粘固剂或树脂改性玻璃离子粘固剂中。从试样制备后直接到长期浸泡在蒸馏水中，测量试样的努普硬度。结果表明，当在两种树脂粘固剂中加入5.0%（重量）时，其硬化性能与无添加剂的对照组相同。此外，在大鼠上颌中切牙的牙冠制备后，用市售的含5.0%（重量）丝胶的树脂改性玻璃离子粘固剂密封临时牙冠。结果表明，在3个月的临时粘固后，角化上皮和附着牙龈的炎症恢复情况与健康牙龈对照组相当。伤口愈合效果未充分显示。

Sericin powder was added in a commercially available self-adhesive resin cement or resin-modified glass ionomer cement with various concentrations. Specimens were measured Knoop hardness from directly after specimen preparation to long-term immersion in distilled water. As a result, it was revealed that the hardening properties were equal to additive-free control when it was added 5.0% by weight in both resin cements.In addition, after crown preparation of the rat maxillary central incisor, temporary crownswere sealed with commercially available resin-modified glass ionomer cement containing sericin 5.0% by weight. As a result, the recovery of inflammation of a cornification epithelium and the attached gingiva seated the temporary crown with sericin-containing resin-modified glass ionomer cement was equivalent to healthy gingival control group after 3-months provisional cementation. The wound healing effect was not shown enough.
