Abstract
Introduction
Historically, abrasive materials such as marble powders, corals and bone ashes were used for dental hygiene. With evolution, these materials were replaced by dentifrices applied on toothbrushes for the same purpose.
Objective
To evaluate, through Optical Coherence Tomography, the wear of dental enamel after the use of different toothbrushes and materials used in brushing with abrasive components.
Material and method
50 specimens were prepared, distributed in 10 groups (n=5) according to the toothpaste used. For group A, the Curaprox® Adult Ultra Macia toothbrush was used and for group B, the soft toothbrush K® - soft adult toothbrush. The following brushing materials were used: Curaprox® Black is White; Colgate® Luminous White Instant, Close Up® White Attraction - MenSuperpure; Activated Charcoal; Distilled Water. The images were performed before and after the brushing cycle and were compared for surface changes. The loss of the surface structure was evaluated through qualitative and quantitative methods. Statistical analysis of the data was performed using the statistical methods Mann-Whitney, Kruskal-Wallis, with significance level of 5%, mean, standard deviation, median and percentiles.
Result
A higher index of loss of enamel structure was observed in the G2A (16.09) and G2B (11.38) groups and a lower structural loss rate in the specimens corresponding to the groups G5A (1,07) and G5B (1,20).
Conclusion
Through this study it was observed that the whitening dentifrices and the Activated Charcoal are able to promote an intense wear of the dental enamel.
