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.
Highlights
Dental fluorosis is a developmental disturbance of enamel caused by excessive intake of fluoride during tooth formation [1] and characterized by the presence of bilateral, diffuse, thin and horizontal white striations and stained areas
A review evaluated the relationships between perceptions of dental appearance⁄ oral health-related quality of life (OHRQoL) with dental fluorosis and showed that severe fluorosis was consistently reported to be linked to a less favorably dental appearance, having a negative impact on the individuals' OHRQoL [3]
This study report changes in OHRQoL in individuals presenting dental fluorosis that were treated with microabrasion or microabrasion associated with at-home bleaching
Summary
Dental fluorosis is a developmental disturbance of enamel caused by excessive intake of fluoride during tooth formation [1] and characterized by the presence of bilateral, diffuse, thin and horizontal white striations and stained areas. Mild fluorosis appears as opaque⁄ white parchment enamel, while more severe fluorosis can be characterized by brown stains or pitting of enamel. Posteruptive features of dental fluorosis may include pitting and larger surface destructions of enamel [2]. It is possible to observe negative effects of fluorosis, such as embarrassment from or being unhappy with appearance and hindering smiling, especially in cases involving staining or pitting, typical features of moderate to severe fluorosis [4]. A review evaluated the relationships between perceptions of dental appearance⁄ oral health-related quality of life (OHRQoL) with dental fluorosis and showed that severe fluorosis was consistently reported to be linked to a less favorably dental appearance, having a negative impact on the individuals' OHRQoL [3]
