Abstract

AIMS AND OBJECTIVES: The aim of this study was to assess the efficacy of 18% hydrochloric acid and 37% phosphoric acid by an in vivo comparison. METHODS: Sixty fluorotic permanent maxillary central incisors from 30 patients were divided into 3 categories. The teeth received 5 seconds (mild fluorosis), 20 seconds (moderate fluorosis) and 30 seconds (severe fluorosis) application of 18% hydrochloric acid on 11 and 37% phosphoric acid on 21. Standardized intraoral photographies were taken immediately before, after, and one month after treatment. Vinyl polysiloxane impression of the patient were made before and after the treatment. A scanning electron microscopic (SEM) evaluation was carried out on the models to judge the surface alterations. Wilcoxon and Mann-Whitney tests were used to verify the hypothesis. RESULTS: A statistically significant result was obtained in the reduction of white spot opacities, intensity of stains and the total area occupied by the stains in mild and moderate fluorosis teeth. Results of severe fluorosis had an unpredictable outcome. An SEM evaluation revealed good improvement in the surface texture of mild and moderate fluorosis teeth. Teeth with severe fluorosis showed only a slight improvement. CONCLUSION: A microabrasion procedure is effective for treating mild and moderate fluorosis cases.

    OBJECTIVE: To compare in vivo the efficacy of enamel microabrasion alone or in combination with vital tooth bleaching for the management of tooth discoloration caused by fluorosis. METHODS: A total of 118 maxillary and mandibular fluorosed incisors and canines in 10 patients, scored from 1 to 7 according to the Tooth

  • A simple technique for removal of mottling, opacities and pigmentation from enamel

    Mottling of teeth can have significant psychological impact on patients--particularly on adolescents, who may be subjected to much unkind teasing. A number of procedures have been suggested for removal of mottling and stains. The authors describe a simple and quick technique using a paste of hydrochloric acid and pumice, and

  • Clinical management of severe fluorosis in an adult

    Dental fluorosis is defined as hypomineralisation of enamel resulting from excessive ingestion of fluoride (more than 1 ppm) during tooth development. Mild-to-moderate forms of dental fluorosis are often unnoticed by the patients whereas severe fluorosis presents with dark brown-to-black discolouration of teeth along with enamel pitting and hypoplasia. Such discolouration results

  • Aesthetic management of dental fluorosis

    Significant numbers of patients visiting the paediatric dental clinics have aesthetically objectionable brown stains and desire treatment for them. Intrinsic tooth discolouration can be a significant aesthetic, and in some instances, functional, problem. Dental fluorosis, tetracycline staining, localised and chronological hypoplasia, and both amelogenesis and dentinogenesis imperfecta can all produce

    BACKGROUND:  Endemic dental fluorosis has already been described in some regions of the world. The aim of this study was to evaluate the functional and psychosocial impact of direct aesthetic restorative treatments in endemic fluorosis patients in the northern state of Minas Gerais, Brazil. Was a quasi-experimental intervention study. METHODS:  The

    When it comes to how fluoride impacts human health, no tissue in the body has been studied more than the teeth. Yet, despite over 50 years of research, the mechanism by which fluoride causes dental fluorosis (a hypo-mineralization of the enamel that results in significant staining of the teeth) is not

    The traditional criteria (the "Dean Index") for diagnosing dental fluorosis was developed in the first half of the 20th century by H. Trendley Dean.

    Before the widespread use of fluoride in dentistry, dental fluorosis was rarely found in western countries. Today, with virtually every toothpaste now containing fluoride, and most U.S. water supplies containing fluoride chemicals, dental fluorosis rates have reached unprecedented levels. In the 1950s, it was estimated that only 10% of children in

    The vast majority of research has found that patients, parents, and the general public alike view mild fluorosis (TF score 3) as a significant blemish of the teeth, one that is likely to embarrass the affected child to a degree that cosmetic treatment would be warranted.
