Abstract

Introduction: Activated charcoal-based products have been marketed as teeth whiteners and are widely used by the population without any quality control or studies on their impact on dental structure.

Objective: The objective of this study was to evaluate the effect of brushing with powdered coconut-based products on the roughness and color of human dental enamel.

Material and method: To this end, 40 enamel samples with 6mm diameter were stained with coffee for 36 hours. Initial roughness readings (Ra and Rz) and color (L* a * b*) were performed. The specimens were divided into 4 groups (n = 10): Control Group: Colgate Total 12 toothpaste; CBP Group: Activated Coconut Charcoal Powder, Black Pearl Tooth Powder; CAC Group: Activated Coconut Charcoal Powder, Activated Charcoal Tooth Whitening Powder; Group BS: Sodium bicarbonate powder. The specimens were submitted to abrasive cycles for brushing simulation (945, 4.050 and 49.275 cycles), and upon completion of these cycles, new measurements of color and roughness were taken. A 1-factor ANOVA analysis was performed to analyze the color variation and roughness data, followed by the Tukey test.

Result: There was no statistical difference between the initial and final roughness in any of the groups studied. For the color data, there was no statistical difference for the L* coordinate for any group. For the coordinates a * and b* there was a difference for all groups between the initial period and all the others.

Conclusion: Even after the one-year period brushing simulation, the surface roughness of the enamel of none of the products studied was affected. The color of the enamel after the accomplishment of the abrasive cycles occurred in a similar way in the experimental groups based on activated coconut charcoal and conventional toothpaste.

Resumo

Introdução: Produtos a base de carvão ativado vem sendo comercializados como branqueadores dentais e amplamente utilizados pela população sem qualquer tipo de controle de qualidade ou estudo sobre suas repercussões sobre a estrutura dental.

Objetivo: O objetivo desse estudo foi avaliar o efeito da escovação com produtos à base de carvão ativado sobre a rugosidade e cor de esmalte dentário.

Material e método: Quarenta amostras de esmalte com 6mm de diâmetro foram manchadas com café durante 36 horas. Foram realizadas leituras iniciais de rugosidade (Ra e Rz) e cor (L*a*b*). Os espécimes foram divididos em 4 grupos (n=10): Grupo Controle: Creme dental Colgate Total 12; Grupo CBP: Pó de carvão de coco ativado Black Pearl Tooth Powder; Grupo CAC: Pó de carvão de coco ativado Activated Charcoal Teeth Whitening Powder; Grupo BS: Pó de Bicarbonato de sódio. Os espécimes foram então submetidos a ciclos de simulação de escovação (945, 4.050 e 49.275 ciclos), sendo que ao alcançar cada uma dessas marcas, novas medidas de cor e rugosidade foram tomadas. Para analisar os dados de variação de cor e rugosidade foi realizada a análise ANOVA 1-fator, seguida pelo teste de Tukey.

Resultado: Não houve diferença estatística entre a rugosidade inicial e final em nenhum dos grupos estudados. Para os dados de cor, houve diferença estatística para as coordenadas a* e b* em todos os grupos entre o período inicial e os demais.

Conclusão: Mesmo após a simulação de escovação referente ao período de um ano nenhum dos produtos estudados afetou a rugosidade superficial do esmalte. A cor do esmalte após realização dos ciclos abrasivos deu-se de forma semelhante nos grupos experimentais a base de carvão de coco ativado e com o creme dental convencional.
