PURPOSE
This study compares the ability of extrinsic stain removal and surface roughness changes on tooth surfaces after using two different types of dental air polishing powder: Sodium bicarbonate and novel eggshell powder.
METHODS
For the study of extrinsic stain removal, twenty bovine teeth were soaked in coffee for extrinsic stain formation. Group 1 and Group 2 were polished with sodium bicarbonate powder and novel eggshell powder, respectively. The acquired stains of teeth were recorded as baseline, and color changes after cleaning with two different powders were also measured by colorimeter. Sixteen samples from eight human posterior teeth were used for the surface roughness test. Surface roughness values (S) of two groups (sodium bicarbonate and novel eggshell powder) were measured by a contact-type profilometer before and after polishing with two types of powders.
RESULTS
The data showed that the average ΔE* value of the sodium bicarbonate group was higher than that of the novel eggshell powder group (P < 0.05). The average ΔS value of the sodium bicarbonate group was higher than that of the novel eggshell powder group (P < 0.05).
CONCLUSION
Sodium bicarbonate powder showed higher stain removal ability and surface roughness changes than the novel eggshell powder.
目的
本研究比较了使用两种不同类型的牙科空气抛光粉（碳酸氢钠和新型蛋壳粉）后牙齿表面的外源性污渍去除能力和表面粗糙度变化。
方法
为了研究外源性污渍去除，将20颗牛牙浸泡在咖啡中以形成外源性污渍。第1组和第2组分别用碳酸氢钠粉和新型蛋壳粉进行抛光。将牙齿上获得的污渍记录为基线，并使用色差仪测量用两种不同粉末清洁后的颜色变化。使用来自8颗人类后牙的16个样本进行表面粗糙度测试。用两种类型的粉末抛光前后，通过接触式轮廓仪测量两组（碳酸氢钠和新型蛋壳粉）的表面粗糙度值（S）。
结果
数据显示，碳酸氢钠组的平均ΔE*值高于新型蛋壳粉组（P < 0.05）。碳酸氢钠组的平均ΔS值高于新型蛋壳粉组（P < 0.05）。
结论
碳酸氢钠粉比新型蛋壳粉表现出更高的污渍去除能力和表面粗糙度变化。
