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

将丝胶粉添加到市售的不同浓度的自粘树脂水泥或树脂改性玻璃离子水泥中。从试样制备后直接到长期浸泡于蒸馏水中，测量了试件的努氏硬度。结果表明，当两种树脂胶结物的质量分数为5.0%时，其硬化性能与无添加剂控制相同。此外，在大鼠上颌中切牙冠制备完成后，用市售的含5.0%丝胶的树脂改性玻璃离子水门汀密封临时冠。结果显示，采用含丝胶树脂改性玻璃离子水门汀固定临时冠3个月后，角膜化上皮和附着龈的炎症恢复与健康牙龈对照组相当。创面愈合效果不明显。

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.
