Pulpal injury commonly occurs with tooth preparation for complete fixed partial dentures. This can be documented by the substantial incidence of pain after tooth preparation. In this study, a 4% potassium nitrate-zinc oxide eugenol temporary cement was used to secure provisional crowns over recently prepared teeth and it significantly reduced the incidence and severity of pain after tooth preparation and impression taking.
牙髓损伤常见于全固定局部义齿的牙体预备过程中。这可以通过牙体预备后疼痛的高发生率得到证实。在本研究中，一种含4%硝酸钾的氧化锌丁香酚水门汀被用于在近期预备的牙齿上固定临时冠，它显著降低了牙体预备和取印模后疼痛的发生率及严重程度。
