夹层技术用于老年人活髓牙Ⅱ类洞充填效果分析

The effect analysis in filling type II cavity in vital pulp teeth of elderly using sandwich technique

目的:探讨夹层技术对老年人活髓牙Ⅱ类洞充填效果。方法:将活髓后牙制备成Ⅱ类洞形后①实验组玻璃离子垫底、酸蚀、粘结后,卡瑞斯玛PPF树脂充填②对照组:直接用卡瑞斯玛PPF树脂充填。结果:经5年的临床观察,实验组46例69颗牙,成功61颗,失败8颗,成功率88.41%。对照组18例35颗牙,成功22颗,失败13颗,成功率62.86%。结论:随着年龄的增长,老年期间口腔咀嚼功能的减弱,应用夹层技术结合PPF复合树脂充填活髓牙Ⅱ类洞,远期疗效可靠,其修复的美观性、耐磨性是可行的,但对大样本量病例,尚有待进一步观察。

Objective: To explore the curative effect of filling type II cavity in vital pulp teeth of elderly by using sandwich technique. Methods: After preparing type II cavity in vital pulp teeth, teeth in study group were relined with glass ionomer, acid etched, cement spreaded and finally filled with charisma PPF resing, while teeth in control group were directly filled PPF resing. Results: 5 years later, it's observed that the successful filling rate in study group is 88.41% and that in control group is 62.86%. Conclusion: Sandwich technique combined with PPF resing has long-term effectiveness in the type II cavity filling in elderly people, it has reliable aesthetic and wear-resisting property.
