目的评价双重固化高强度复合树脂水门汀和树脂加强型玻璃离子水门汀黏固纤维桩的临床效果。方法选择2007年在沈阳沈河金英武口腔诊所就诊,拟采用纤维桩修复的70例前磨牙或第一磨牙缺损患者的96颗患牙,随机分为2组,每组48颗,分别用不同的黏结剂(Ⅰ组:双重固化高强度复合树脂水门汀;Ⅱ组:树脂加强型玻璃离子水门汀)黏固纤维桩,制备树脂桩核,全冠修复。随访2年,观察修复效果。结果Ⅰ组4颗失败,1颗为上颌第二前磨牙纤维桩折断,另3颗为上颌第一前磨牙纤维桩脱落,成功率为91.7%;Ⅱ组2颗失败,1颗为上颌第一前磨牙,另1颗为下颌第一前磨牙,均为纤维桩折断,成功率为95.8%。两组治疗成功率比较差异无统计学意义(P>0.05)。结论 2种黏结剂用于临床黏固纤维桩均表现出良好的临床效果。
Objective To evaluate the clinical effect of double-cured high-strength composite resin cement and resin-reinforced glass ionomer cement fiber cement piles. Methods Sixty-seven teeth of 70 premolar or primary molar defect patients who were to be repaired by fiber post were selected in 2007 at Shenyang Jinhe Stomatological Clinic. They were randomly divided into two groups (48 in each group) Adhesive (Group Ⅰ: double curing high strength composite resin cement; Ⅱ group: resin reinforced glass ionomer cement) cement fiber post, the preparation of resin post core, crown repair. Follow-up 2 years, observe the effect of repair. Results Four patients failed in group Ⅰ, one was broken by the maxillary second premolar fiber pile, and the other three were the maxillary first premolar fiber pile fell off with a success rate of 91.7%. In group Ⅱ, two failed and one was maxillary first Premolar, the other one for the mandibular first premolar, are broken fiber posts, the success rate was 95.8%. There was no significant difference in the success rate of treatment between the two groups (P> 0.05). Conclusions The two kinds of adhesive used in clinical cement fiber post all showed good clinical effect.
