摘要:
目的 比较树脂型窝沟封闭剂、流动树脂、复合体、玻璃离子等材料结合不同粘结系统行窝沟封闭术后的边缘密闭性,为经济欠发达地区寻找简捷有效的防龋措施。 方法 离体牙随机分五组:全酸蚀技术 + 树脂型窝沟封闭剂组(A组,对照组)、自酸蚀粘结剂 + 树脂型窝沟封闭剂组(B组)、自酸蚀粘结剂 + 流动树脂组(C组)、自酸蚀粘结剂 + 复合体组(D组)及玻璃离子组(E组),体外行窝沟封闭并记录操作时间。行体外温度循环后进行扫描电镜及体视显微镜检测。 结果 (1)各组均存在不同程度的微渗漏;(2) B组及C组与对照组(A组)差异有统计学意义(P < 0.05),操作时间短于对照组;(3) D组及E组微渗漏高于对照组(P < 0.05);(4) D组在试件制备过程中无折断及松脱等现象。 结论 自酸蚀粘结系统结合树脂型窝沟封闭剂及流动树脂实施窝沟封闭术时操作简便、微渗漏较低;复合体抗压强度较大。 Abstract:Objective To evaluate marginal integrity and microleakage of resin-based sealant, flowable composite resin, compomer and glass ionomer cement combined with certain adhesive systems, in order to explore a more convenient, effective and time-saving approach which intends to be applied in less developed areas. Methods 65 maxillary premolar teeth were kept in artificial saliva, pits and fissures were cleaned by ART equipments. The samples were allocated into 5 groups randomly: (A) phosphoric acid etching + Concise (control); (B) AdperTM Easy One + Concise; (C) AdperTM Easy One + FiltekTM Z350XT flowable resin; (D) AdperTM Easy One + Dyract Extra compomer; and (E) GC Fuji VII. The pit and fissure sealant were applied, and the operation time was recorded in vitro. After thermocycling, specimens were evaluated by scanning electron microscope and stereomicroscope. Results i) All the groups showed various level of microleakage; ii) Group B and C showed similar microleakage as compared with the control group, while their operation time were shorter than that of the control group (P < 0.05); iii) Group D and E showed greater microleakage than other groups (P < 0.05); iv) No shedding of sealing materials during teeth cutting in Group D. Conclusions Resin-based sealant and flowable composite resin combined with self-etching adhesive system has advantages of operative convenience and effectiveness. Dyract Extra compomer has better abrasion resistance. -
