INTRODUCTION
Calcium sulfate (CaS) is a simple, biocompatible material with a long history of safe use in different fields of medicine. CaS is a rapidly resorbing material that leaves behind a calcium phosphate lattice, which promotes bone regeneration and hemostasis. The aim of this study was a clinical evaluation of the hemostatic effect of CaS hemi-hydrate (CaSO4), commonly known as plaster of Paris, in endodontic surgery.
METHODS
Twenty-four patients with 31 periradicular lesions were enrolled in this study. The apical roots were exposed, and the bleeding would have made it difficult to correctly fill the root-end cavities. To avoid such an inconvenience, the teeth were divided into 3 groups. Hemostasis was attempted by using CaS in 11 teeth (group I), gauze tamponade in another 10 teeth (group II), or 20% ferric sulfate in the last 10 teeth (group III).
RESULTS
Control of the bleeding was achieved in all teeth of group I, whereas in group II adequate hemostasis was achieved in 3 of 10 cases and in group III in 6 of 10 cases.
CONCLUSIONS
The use of CaS completely eliminated the bleeding, with a very good level of hemostasis.
简介
硫酸钙（CaS）是一种简单、生物相容性好的材料，在医学的不同领域已有长期安全应用的历史。CaS 是一种快速吸收的材料，会留下磷酸钙晶格，促进骨再生和止血。本研究的目的是临床评估半水合硫酸钙（CaSO4）（俗称熟石膏）在根管手术中的止血效果。
方法
本研究纳入了 24 名患有 31 个根尖病变的患者。暴露根尖后，出血会使根尖腔的正确填充变得困难。为了避免这种不便，将牙齿分为 3 组。在 11 颗牙齿中尝试使用 CaS 止血（I 组），在另外 10 颗牙齿中使用纱布填塞止血（II 组），在最后 10 颗牙齿中使用 20%硫酸铁止血（III 组）。
结果
I 组所有牙齿均成功控制出血，而 II 组 10 颗牙齿中有 3 颗、III 组 10 颗牙齿中有 6 颗成功达到充分止血。
结论
使用 CaS 完全消除了出血，止血效果非常好。
