摘要：

背景：对于前牙美容修复，树脂充填材料具有牙体损伤小、美观效果佳等特点，但活髓牙充填后常出现敏感等问题，如何选择一种刺激性较小的树脂充填材料尤为关键。
目的：比较3M-Z350纳米复合树脂充填材料与3M-Z100复合树脂充填材料进行活髓前牙美容修复后的敏感发生率及患者自觉疼痛程度的差异。
方法：选择2006-08/12就诊于泸州医学院附属口腔医院口腔内科因龋坏或外伤牙折要求行前牙美容修复的活髓牙患者68例，患牙112颗，随机分为3M-Z350组、3M-Z100组，56颗患牙/组。两组分别对应用3M-Z350纳米复合树脂充填材料及3M-Z100复合树脂充填材料行前牙美容修复。采用Ryge评价标准在修复后不同时间记录对冷刺激的敏感性，采用疼痛程度标尺记录患者自觉疼痛程度。
结果与结论：与3M-Z100组比较，修复1 d、1周、1个月后3M-Z350组敏感发生率及患者自觉疼痛程度均明显降低(P < 0.01或0.05)，修复3个月后上述两项指标无明显差异(P > 0.05)。提示在活髓前牙美容修复过程中，使用3M-Z350纳米复合树脂充填材料在获得良好美容修复效果的同时，可明显降低充填后的敏感发生。

Abstract:

BACKGROUND: Resin filling, full crown and veneer are used in cosmetic restoration of anterior teeth. Doctors prefer resin because of its perfect clinical effect and small hurt. Some patients complain of sensitivity after rsein filling and we are interest in choosing a better resin with less sensitivity.
OBJECTIVE: To compare the incidence of postoperative sensitivity and the difference of the patients’ self sensitivity after cosmetic restoration of anterior teeth with vital pulp by 3M-Z350 Nano-resin and 3M-Z100 composite resin. 
METHODS: A total of 112 teeth with vital pulp because of caries or traumatic tooth fractures of 68 patients demanding cosmetic restoration were selected from the Department of Endodontics, Stomatological Hospital of Luzhou Medical College from August to December 2006. The teeth were random divided into 3M-Z350 group and 3M-Z100 group, with 56 teeth in each group. 3M-Z350 nano-resin and 3M-Z100 composite resin were used for cosmetic restoration of anterior teeth with vital pulp. Ryge criteria were used to evaluate the sensitivity to the cold stimulation following cosmetic restoration, and the level of pain was detected by the pain ruler.
RESULTS AND CONCLUSION: Compared with 3M-Z100 group, the incidence of sensitivity and self-pain level were decreased in the 3M-Z350 group at 1 day, 1 week, and 1 month after restoration (P < 0.01 or P < 0.05). There was no significant difference in the sensitivity and self-pain level between the two groups (P > 0.05). Anterior teeth with vital pulp were well restored by 3M-Z350 nano-resin which might reduce the incidence of postoperative sensitivity.
