摘要

核桃是核桃科的常见成员。近年来,对核桃各部位酚类物质含量和抗氧化活性的研究日益受到人们的关注。牙齿变色的原因有很多,因为牙齿会吸收茶、咖啡和食物中的成分。这些成分造成的污渍可能会留在多孔的牙釉质层中。传统的美白化学物质有一些副作用,最常见的是牙齿敏感和轻度或中度的牙龈刺激。本实验旨在评价核桃干壳提取物的美白效果,并与传统的预防性浮石进行比较。收集了40颗人类牙齿。在这些牙齿中,20颗是恒牙,另外20颗是乳牙。每组随机分为研究组(用干壳提取物处理)和对照组(用传统浮石处理)。用Easy VitaShade Advanced 4.0测量牙齿颜色,并记录每颗牙齿抛光前后的亮度、色度和色调读数(a∗代表绿色到红色轴,b∗代表蓝色到黄色轴)。使用社会科学统计软件包(版本22;芝加哥,伊利诺伊州,美国)。采用Shapiro-Wilk、Wilcoxon和秩、Wilcoxon符号秩检验对数据进行分析,显著性水平设为0.05。使用夏皮罗-威尔克检验进行正态性检验,结果表明颜色变量不是正态分布。乳牙和恒牙的牙齿亮度差异有统计学意义,其中牙釉质的美白效果明显优于浮石,差异有统计学意义(p < 0.05)。本研究支持在牙科中使用核桃干壳提取物作为具有美白效果的天然产品。由于其有益特性和高活性成分,它在牙科方面具有利用潜力。

Whitening Effect of Juglans regia Dry Husk Extract on Primary and Permanent Teeth.

Walnut is a common member of the family Juglandaceae. Recently, the evaluation of the phenolic content and antioxidant activity of the parts of walnut has received increased interest. Many reasons are responsible for teeth discolouration because teeth can absorb ingredients from tea, coffee, and food. Stains from these ingredients could stay in the porous enamel layer. Traditional whitening chemicals have some side effects, the most common of which is tooth sensitivity and mild or moderate gingival irritation. The aims of this comparative experimental study were to evaluate the whitening effect of Juglans regia dry husk extract and compare it with that of traditional prophylactic pumice. Forty human teeth were collected. Amongst these teeth, 20 were permanent, and the other 20 were primary. Each group was randomly divided into a study group (treated with dry husk extract) and a control group (treated with traditional pumice). Tooth colour was measured with Easy VitaShade Advanced 4.0, and the readings of lightness, chroma, and hue (a represents the green to red axis and b represents the blue to yellow axis) were documented for each tooth before and after polishing. A statistical analysis was performed using the Statistical Package for Social Science (version 22; Chicago, Illinois, USA). Data were analysed using Shapiro-Wilk, Wilcoxon sum rank, and Wilcoxon signed rank tests, and the level of significance was set to 0.05. A normality test was conducted using the Shapiro-Wilk test, and it showed that the colour variables were not normally distributed. With regard to tooth lightness, significant differences were observed in the primary and permanent teeth and Juglans regia exerted a much better whitening effect than pumice at p < 0.05. This study supports the use of Juglans regia dry husk extract in dentistry as a natural product with a whitening effect. It has utilisation potential in dentistry due to its beneficial properties and highly active components.
