摘要:
[摘要]目的：探讨纳米复合树脂与光固化复合树脂在老年牙体缺损修复中的应用价值。方法：选取笔者医院2015年5月-2017
年5月收治的老年牙体缺损患者116例，根据患者所应用的修复材料分成纳米组（n =58）、光固化组（n =58）。纳米组采用纳
米复合树脂修复，光固化组采用光固化复合树脂修复，随访24个月。比较两组修复效果，分析两组治疗后6、12、24个月的
釉质、釉质咬合接触区磨耗深度。根据患者牙齿修复情况对边缘适合性、边缘变色、表面光滑性及色泽匹配性进行评分，分
析牙齿美观度，并观察两组并发症情况。结果：纳米组总优良率为94.83%，高于光固化组的82.76%，两组比较差异有统计学
意义（P ＜0.05）。两组治疗后12、24个月的釉质、釉质咬合接触区磨耗深度均高于治疗后6个月，且纳米组显著低于光固化
组（P ＜0.05）。两组治疗后边缘适合性、边缘变色、表面光滑性、色泽匹配性评分均高于治疗前，且纳米组边缘适合性、
边缘变色评分显著高于光固化组（P ＜0.05）。纳米组牙敏感发生率为1.72%，显著低于光固化组的12.07%（P ＜0.05）。 结
论：与光固化复合树脂相比，纳米复合树脂的修复效果更好，且能减少釉质、釉质咬合接触区的磨耗深度，进一步改善患牙
边缘适合性及边缘变色，降低牙敏感发生率。

Abstract:
Abstract:Objective To explore the application value of nano-composite resin and light-cured composite resin in the restoration
of senile dental defects. Methods 116 elderly patients with dental defects admitted to our hospital from May 2015 to May
2017 were divided into nano group (n =58) and light curing group (n =58) according to the materials used by the patients.The
nano-group was repaired with nano-composite resin, and the light-cured group was repaired with light-cured composite resin.
The follow-up period was 24 months.The repairing effect was compared between the two groups, and the wear depth of
enamel and enamel occlusal contact area was analyzed 6, 12 and 24 months after treatment.According to the patient’s
dental restoration situation, the marginal fitness, edge discoloration, surface smoothness and color matching were scored,
and the aesthetic degree of teeth was analyzed, and the complications of the two groups were observed. Results The total
excellent and good rate of nano-group was 94.83%, which was higher than that of photo-curing group (82.76%). The
difference was statistically significant(P ＜0.05).The wear depth of enamel and enamel occlusal contact area in the two
groups at 12 and 24 months after treatment was higher than that at 6 months after treatment, and the wear depth in the
nano group was significantly lower than that in the light curing group (P ＜0.05).After treatment, the scores of edge fitnes s,
edge discoloration, surface smoothness and color matching in the two groups were higher than those before treatment,
and the scores of edge fitness and edge discoloration in the nano group were higher than those in the light curing group
(P ＜0.05).The incidence of dental sensitivity in nano-group was 1.72%, which was significantly lower than that in lightcured
group (12.07%) (P ＜0.05). Conclusion Compared with light-cured composite resin, nanocomposite resin has better
restoration effect, and can reduce the wear depth of enamel and enamel occlusal contact zone, further improve the marginal
fitness and discoloration of affected teeth, and reduce the incidence of tooth sensitivity.
