Dental Fluorosis Treatment Can Improve the Individuals’ OHRQoL? Results from a Randomized Clinical Trial

Abstract

This study aimed to evaluate the effect on oral health-related quality of life (OHRQoL) of two treatment protocols for dental fluorosis in individuals enrolled in a randomized clinical trial. Seventy volunteers, who lived in a fluorosis endemic area in Brazil, and had at least four maxillary anterior teeth showing fluorosis with a Thylstrup and Fejerskov index from 1 to 7, were randomized into two treatment groups (n= 35): GI- enamel microabrasion; or GII- microabrasion associated with at-home bleaching. Microabrasion was performed using 37% phosphoric acid and pumice, and at-home tooth bleaching with 10% carbamide peroxide in a tray. Volunteers completed a questionnaire at baseline and 1-month post treatment to assess changes in OHRQoL, using the Oral Impact on Daily Performance (OIDP). Differences in overall impact scores between and within treatment groups were analyzed with Wilcoxon (within) and Mann-Whitney (between) tests. Changes in performance scores were analyzed using Wilcoxon tests (a< 0.05). One month after treatment, subjects reported improvement in OHRQoL. Both groups showed lower OIDP scores (p< 0.001), but there was no difference between them. Eating, cleaning teeth, smiling and emotional state performance scores were lower after treatment for the whole sample. In conclusion, the treatment with microabrasion improved the OHRQoL in this sample of individuals living in a fluorosis endemic area regardless of the addition of at-home bleaching.

Change in Oral Health-Related Quality of Life Following Minimally Invasive Aesthetic Treatment for Children with Molar Incisor Hypomineralisation: A Prospective Study

“…Clinical-based investigations in young children, with any type of enamel defect, are sparse [2,18,19]. However, a recent randomised clinical trial did demonstrate improved OHRQoL following microabrasion/tooth whitening for young Brazilian adults with dental fluorosis [28]. Although not a universal finding, some OHRQoL studies have shown gender differences, with girls reporting lower OHRQoL than boys, in relation to a variety of dental conditions [29,30].…”

Avaliação da eficácia da microabrasão no tratamento de manchas de fluorose: revisão de literatura

“…Meireles et al 9 concluíram em seu trabalho que a microabrasão reduziu a QVRSB dos pacientes que viviam em uma área de fluorose endêmica, independente da aplicação do clareamento caseiro, entretanto Oliveira et al 10 relatam em seu estudo que a indicação da técnica de microabrasão deve ser levada em consideração que pode ter uma extensão superficial ou ser mais profunda, concluindo que em alguns casos o procedimento de microabrasão pode produzir apenas discreta melhora no aspecto clínico, o que deve ser discutido com o paciente.…”

“…Com um contra-ângulo com redutor de velocidade começa a remover a camada superficial, com cautela, até encontrar o esmalte normal, é importante ressaltar que ao final de cada período os dentes sejam lavados com água abundante. Posteriormente é realizado o polimento do esmalte dentário com disco de feltro ou borrachas abrasivas de granulação fina e pasta para polimento 1,5,9 .…”

Tratamiento estético en fluorosis dental grado 3 según índice Thylstrup y Fejerskov, mediante métodos conservadores

“…Dentro de los componentes estéticos de una persona, la sonrisa constituye uno de los elementos fundamentales para su comunicación y relacionamiento con su entorno social 26 , ésta puede ser capaz de transmitir el estado de ánimo de un individuo 27 . La FD generalmente es asintomática, pero desarrolla impacto psicológico negativo dentro de las personas, especialmente en jóvenes [28][29][30] .…”
