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.

    STATEMENT OF THE PROBLEM: The clinical performance of enamel microabrasion alone for aesthetic management of dental fluorosis is debatable. PURPOSE OF THE STUDY: This study aimed to compare the clinical efficacy of enamel microabrasion for the aesthetic management of mild-to-severe dental fluorosis. METHODS/MATERIALS: A total of 154 fluorosed incisors and

  • 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

  • Re-establishing esthetics of fluorosis-stained teeth using enamel microabrasion and dental bleaching techniques

    Dental fluorosis manifests itself as white stains on the enamel of teeth exposed to excessive doses of fluoride during their formation. Fluorosis usually occurs as a result of the ingestion of dentifrices, gels and fluoridated solutions. It may be diagnosed as mild, moderate or severe, and in some cases, it

    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

    Bleaching is a conservative method for restoring the colour of intrinsic discoloration of teeth. The combination of McInnes solution and power bleaching is effective procedure for bleaching of fluorosis stained teeth. Definitely bleaching with McInnes bleaching agent gives instant results, not dependent on patient's compliance as other office based procedures,

  • Dental Fluorosis Is a "Hypo-mineralization" of Enamel

    Teeth with fluorosis have an increase in porosity in the subsurface enamel ("hypomineralization"). The increased porosity of enamel found in fluorosis is a result of a fluoride-induced impairment in the clearance of proteins (amelogenins) from the developing teeth. Despite over 50 years of research, the exact mechanism by which fluoride impairs amelogin

  • Moderate/Severe Dental Fluorosis

    In its "moderate" and severe forms, fluoride causes a marked increase in the porosity of the enamel. After eruption into mouth, the porous enamel of moderate to severe fluorosis readily takes up stain, creating permanent brown and black discolorations of the teeth. In addition to extensive staining, teeth with moderate to severe fluorosis are more prone to attrition and wear - leading to pitting, chipping, and decay.

  • Dental Fluorosis Impacts Dentin in Addition to Enamel

    Dental fluorosis is a mineralization defect of tooth enamel marked by increased subsurface porosity. The enamel, however, is not the only component of teeth that is effected. As several studies have demonstrated, dental fluorosis can also impair the mineralization of dentin as well. As noted in one review: "The fact that

  • Community Fluorosis Index (CFI)

    The current Community Fluorosis Index for U.S. adolescents as a whole (from both fluoridated and non-fluoridated areas) is roughly 5 times higher than the CFI health authorities predicted for fluoridated areas when fluoridation first began. It is also higher than the CFI that the NIDR found in fluoridated areas back in the 1980s. It is readily apparent, therefore, that children are ingesting far more fluoride than was the case in the 1950s, and even as recently as the 1980s.
