傳統的玻璃離子：強度較小，用于乳牙充填、恒牙ⅢⅣ類洞和楔狀缺損的修復。1 玻璃離子水門汀與樹脂的比較，GIC對牙體的粘結強度低于復合樹脂，但與牙體之間的微滲漏與復合樹脂相似。由于GIC凝固收縮明顯低于復合樹脂，可以不要求玻璃離子要有樹脂那樣高的粘結強度。GIC缺點：外觀不如復合樹脂；而且不透明；不易進行拋光處理。牙髓刺激性（小→大）：氧化鋅丁香酚水門汀<聚羧酸性水門汀<玻璃離子水門汀<磷酸鋅水門汀粘結性（大→小）：玻璃離子水門汀>磷酸(suan)鋅水門(men)汀(ting)、聚(ju)羧酸(suan)鋅水門(men)汀(ting)(臨(lin)床上，粘接用聚(ju)羧酸(suan)鋅水門(men)汀(ting)較常用于與修復(fu)體的粘結(jie))。適用于暫(zan)封的材料特性：溶解性小。華中丁(ding)香酚水門(men)汀(ting)型號水門(men)汀(ting)的使用可以提高(gao)口腔衛生水平，減少口腔疾病的發(fa)生率(lv)。
