摘要:

背景:与传统复合树脂相比,3M Z350纳米树脂具有良好的耐磨性、物理机械特性、抛光性,对牙髓刺激小。但成功的树脂黏结修复技术不仅需要好的充填材料,更需要有效可靠的牙体-修复体黏结界面。

目的:比较自酸蚀黏结剂Adper Easy One与全酸蚀黏结剂Single Bond 2在前牙纳米树脂黏结修复中的临床效果。

方法:将需要行3M Z350纳米树脂修复的120 颗活髓前牙完全随机分为2 组,分别采用自酸蚀黏结剂Adper Easy One和全酸蚀黏结剂Single Bond 2 行黏结修复。于修复后即刻、6 个月、1 年、2年对患者进行回访,检查修复体与牙体之间色泽是否协调,修复体与牙体之间是否密合,修复体表面是否完整,无松动,有无染色及继发龋,牙体的牙髓状况及有无冷热刺激痛。

结果与结论:两组修复后即刻、6个月、1年的充填效果比较差异无显著性意义(P > 0.05);自酸蚀黏结剂组修复后2年的牙髓病变率小于全酸蚀黏结剂组(P < 0.05),在色泽不协调、边缘不密合、修复体不完整、继发龋方面,自酸蚀黏结剂组分别出现1,6,0,2例,全酸蚀黏结剂组分别出现0,2,1,2例,两组4个方面的发生率差异无显著性意义(P > 0.05)。结果表明 3M Z350纳米树脂与自酸蚀黏结系统Adper Easy One在活髓前牙黏结修复2年复诊期内牙髓病变率低,均可达到较好的临床效果。

Abstract:

BACKGROUND: Compared with the conventional composite resin, the 3M Z350 nano-resin has good wear resistance, physical mechanical properties, and polishing, and exerts a lower irritation to the dental pulp. Besides filling materials, a reliable tooth-prosthesis bonding interface is necessary for resin bonded repairs.

OBJECTIVE: To compare the clinical effects of self-etch bonding Adper Easy One and total-etch bonding Single Bond 2 on nano-resin bonding restoration of the anterior teeth.

METHODS: 120 anterior teeth with vital pulp, which had defects at the incisal ends and were to be restored with nano resins, were divided into two groups randomly. Two kinds of adhesives, self-etch adhesive and total-etch adhesive, combined with nano-resin were used to restore the teeth. The patients were re-examined immediately, 6 months, 1 year and 2 years after the treatment. The fillings, teeth and pulps of patients were examined, including whether the prosthesis and tooth color were coordinated, whether the gap between the prosthesis and the teeth were sealed, whether the surface of the prosthesis was intact with no loose, whether the prosthesis and teeth had no staining and secondary caries, whether the condition of the tooth pulp had hot or cold stimulation-induced pain.

RESULTS AND CONCLUSION: No significant difference in the filling effects was found between the two groups when the patients were re-examined immediately, 6 months and 1 year after the treatment (P > 0.05). The pulp lesions of the self-etching group were fewer than those of the total-etch group 2 years after the treatment (P < 0.05). Self-etching group had 1, 6, 0, 2 cases and total-etch group had 0, 2, 1, 2 cases in uncoordinated color, edge seal, incomplete restoration and secondary caries, respectively. No statistically significant differences were found in these four aspects between the two groups (P > 0.05). The 2-year follow up showed a low incidence of pulp lesions and satisfactory clinical performance after 3M Z350 nano-resin working with self-etching bonding system in the nano-resin filling of anterior teeth with vital pulp.
