Objective Assess the effects of activated charcoal‐based products on whitening and changes on dental enamel surface. Material and Methods Fifty‐two blocks of bovine dental enamel were randomly distributed in four groups (n = 13): brushing with activated charcoal‐based powder (PW); brushing with activated charcoal‐based dentifrice (AC); brushing with a conventional dentifrice containing 1450 ppm of fluoride (CD); and whitening with 10% carbamide peroxide (CP). Color, microhardness, and surface alteration were analyzed at baseline and after 14 days of treatment. Three samples per group were randomly selected and examined using scanning electron microscopy (SEM) to analyze the morphology. Results PW exhibited greater color change for the ΔE00, ΔWID, Δb* and ΔL* parameters than other groups (p < 0.05). After treatment, microhardness decreased in AC and CP groups (p < 0.05). Also, PW and AC groups showed more surface alteration than CD and CP (p < 0.001). Changes in the morphology of dental enamel were observed by SEM in PW and AC groups. Conclusion Activated charcoal‐based products showed a lower whitening effect than 10% carbamide peroxide. These products also influenced dental enamel microhardness, resulting in greater surface alteration. Clinical Significance Activated charcoal‐based products promoted minimum whitening effects with significant enamel surface alteration. The 10% carbamide peroxide was more effective for whitening and caused slight enamel surface alteration.
Os padrões de beleza estabelecidos pela sociedade vêm sendo um fator decisivo para o aumento de pacientes à procura da odontologia estética a fim de obterem um sorriso harmonioso. Dentro desse contexto, as queixas mais frequentes acerca do tratamento odontológico que visa melhorar a aparência do sorriso são as alterações de cor, forma e tamanho dos dentes. Objetivou-se com esse trabalho relatar um caso de resolução estética em que a paciente se queixava de múltiplos diastemas após o tratamento ortodôntico. Utilizou-se a reanatomização dos elementos 13 ao 23 pela técnica direta em resina composta com o auxílio da guia palatina. Os resultados obtidos evidenciaram que a técnica embasada em planejamento prévio acurado é capaz de resolver casos estéticos com rapidez, segurança e previsibilidade. Assim sendo, concluiu-se que as resinas compostas permitem a reabilitação estética do sorriso de forma direta, com um bom custo-benefício e resultados estéticos excelentes. Ademais, observou-se que a reanatomização dentária com o objetivo de finalização pós-ortodôntica pode ser necessária em casos que requerem mudanças em proporções dentárias.
