To study the clinical effect of Gelatamp colloidal silver gelatin sponge on preventing the complication of teeth extraction.
672 teeth were divided into experimental group and control group semi-randomly. All teeth were extracted after local anesthesia and sockets were cleaned. Gelatamp colloidal silver gelatin sponge was implanted into socket in experimental group and nothing was implanted into alveolar socket in control group. The complication of teeth extraction was observed on 0.5 h, 2 d and 7 d after extraction. The incidence rate of complication was calculated.
The incidence rate of complication of teeth extraction in experimental group was 7.72%, which was lower than that of control group (24.43%). There was significant difference in the incidence rates of complication between experimental group and control group (P < 0.05). The incidence rate of bleeding, infection, pain, swelling and dry socket after teeth extraction in experimental group was lower than those of control group, and the difference between them was statistically significant (P < 0.05).
The results demonstrate that Gelatamp colloidal silver gelatin sponge can prevent the occurrence of complication of teeth extraction, this can be used in clinic.
研究明胶海绵胶体银明胶海绵预防拔牙并发症的临床效果。
将672颗牙齿半随机分为实验组和对照组。所有牙齿均在局部麻醉下拔除，拔牙窝清理后，实验组拔牙窝植入明胶海绵胶体银明胶海绵，对照组拔牙窝不植入任何材料。于拔牙后0.5小时、2天和7天观察拔牙并发症情况，计算并发症发生率。
实验组拔牙并发症发生率为7.72%，低于对照组（24.43%）。实验组与对照组并发症发生率差异有统计学意义（P<0.05）。实验组拔牙后出血、感染、疼痛、肿胀及干槽症的发生率均低于对照组，差异有统计学意义（P<0.05）。
结果表明明胶海绵胶体银明胶海绵可预防拔牙并发症的发生，可应用于临床。
