Abstract

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_a) 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_a 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.

从天然蛋壳中提取的新型空气抛光粉。

目的：本研究比较了使用碳酸氢钠和新型蛋壳粉两种不同类型的牙科空气抛光粉后牙齿表面的外源性去污能力和表面粗糙度变化：为了研究外源性去污，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 组分别使用碳酸氢钠粉和新型蛋壳粉抛光。记录牙齿获得的污渍作为基线，并用色度计测量两种不同粉末清洁后的颜色变化。8 颗人类后牙的 16 个样本被用于表面粗糙度测试。用接触式轮廓仪测量了两组（碳酸氢钠和新型蛋壳粉）在使用两种粉抛光前后的表面粗糙度值（Sa）：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ΔSa值高于新型蛋壳粉组（P < 0.05）：结论：碳酸氢钠粉的去污能力和表面粗糙度变化均高于新型蛋壳粉。
