Abstract

AIM

The objective of this research was to determine the abrasive and remineralising efficacy of quail eggshell (Coturnix coturnix) incorporated into a new experimental toothpaste.

METHODS

An experimental study was designed to compare the surface microhardness of the dental enamel of bovine lateral incisors exposed to different toothpastes. In relation to microroughness (abrasive efficiency), the unit of analysis was each specimen with 16 polymethylmethacrylate (PMMA) blocks. For the remineralisation variable, the unit of analysis was each bovine lateral incisor tooth. A sample size of 16 was determined for each group.

RESULTS

The unpolished PMMA specimens presented the highest mean surface microroughness with a mean of 4.60 ± 1.47 µm, whilst the quail paste, universal polishing paste, control paste, and Diamond Excel Paste showed a mean of 1.16 ± 0.40 µm, 0.63 ± 024 µm, 0.45 ± 0.22 µm, and 0.43 ± 0.17 µm, respectively, presenting significant differences (P < .001). When comparing the surface microhardness of bovine lateral incisor dental enamel exposed to different toothpastes, the universal polishing paste presented the lowest microhardness, with 192.43 ± 56.21 kg/mm, whilst the quail paste presented the greatest remineralising effect, with the highest average of 272 ± 21.18 kg/mm, followed by the control paste with 244 ± 41.43 kg/mm and the Diamond Excel Paste with 228.72 ± 43.72 kg/mm. These differences were statistically significant (P < .001).

CONCLUSIONS

Significant differences were found in the surface abrasive efficiency (microroughness) of PMMA subjected to different toothpastes. The quail toothpaste presented statistically significant results compared to the control pastes, the Diamond Excel Paste, and the universal polishing paste.

摘要

目的

本研究旨在确定鹌鹑蛋壳（ Coturnix coturnix ）在新型实验牙膏中的研磨和再矿化效果。

方法

设计了一项实验研究，以比较暴露于不同牙膏的牛侧切牙牙釉质的表面显微硬度。就微观粗糙度（研磨效率）而言，分析单位为每个 16 个聚甲基丙烯酸甲酯（PMMA）块的样本。对于再矿化变量，分析单位为每个牛侧切牙。每个组的样本量确定为 16 个。

结果

未经抛光的 PMMA 标本具有最高的平均表面微观粗糙度，平均值为 4.60 ± 1.47 µm，而鹌鹑膏、通用抛光膏、对照膏和 Diamond Excel 膏的平均值分别为 1.16 ± 0.40 µm、0.63 ± 024 µm、0.45 ± 022 µm 和 0.43 ± 0.17 µm，差异有统计学意义（P <.001）。当比较暴露于不同牙膏的牛侧切牙牙釉质的表面显微硬度时，通用抛光膏的显微硬度最低，为 192.43 ± 56.21 kg/mm，而鹌鹑膏的再矿化效果最大，平均硬度最高，为 272 ± 21.18 kg/mm，其次是对照膏，为 244 ± 41.43 kg/mm， Diamond Excel 膏为 228.72 ± 43.72 kg/mm。这些差异具有统计学意义（P <.001）。
