Mechanical properties of toothpastes with diamond abrasives


Hamza, Blend; Attin, Thomas; Paqué, Pune Nina; Wiedemeier, Daniel B; Wegehaupt, Florian J (2020). Mechanical properties of toothpastes with diamond abrasives. Journal of Esthetic and Restorative Dentistry, 32(4):416-423.

Abstract

Objective: The aim of this study was to evaluate and compare surface roughness, gloss, and color change of dental enamel after being brushed with toothpastes containing diamond powder and traditional abrasives.
Materials and methods: Seventy enamel slabs were derived from 70 bovine incisors. The slabs were brushed with six different toothpastes and artificial saliva as a negative control. The specimens were then stained with black tea mixed with citric acid (3 days, pH = 4) and again brushed with the same toothpastes. Ra (contact profilometer), gloss (glossmeter), and color (CIE L* a* b* system) values were measured after each step.
Results: Emoform-F Diamond (contains diamond powder and traditional abrasives) offered significantly the best improvement of Ra and gloss values after the first brushing sequence and the best recovery of the brightness of enamel after staining and second brushing sequence (P < .05). AMC 2.5 (contains only diamond powder as abrasive) was not able to offer such improvement.
Conclusion: Diamond powder as an additional abrasive in toothpastes could be able to offer a further improvement of Ra , gloss, and color values of enamel.
Keywords: abrasives; diamond powder; gloss; surface roughness; toothpastes.
