Abstract

The aim of this study was to evaluate the bond strength of three adhesive systems: Excite™, Adper Prompt L-Pop™ and AdheSE One™ to varying degrees of fluorotic enamel using micro-tensile bond strength (?TBS) tests. Human enamel was classified according to the Thylstrup and Fejerskov Index. The interface resin-enamel was observed using stereoscopic and electron microscopy. The Excite™, achieved the highest ?TBS when bonded to healthy enamel and decreased as the degree of fluorosis increased (p<0.05). The Prompt L-Pop™ improved the bonding on moderate and severe fluorosis. The ?TBS of the AdheSE One™, was significantly lower in all degrees of fluorotic enamel (p<0.05) indicating a very poor bonding ability to enamel. These results will provide clinicians with preliminary data to assist them in the selection of the most effective adhesive systems for treatment of fluorosis enamel, resulting in more successful restorative care.

  • Complete oral rehabilitation in a case with severe dental fluorosis

    The authors have presented a technique of full occlusal rehabilitation in a case of severe dental fluorosis. In this technique, maxillary and mandibular anterior teeth were simultaneously prepared and restored first. This was followed by simultaneous preparation of maxillary and mandibular posterior teeth that were restored in canine guided occlusion.

  • Conservative esthetic management of severe dental fluorosis with in-office power bleaching.

    Abstract Fluorosis is an endemic disease, prevailing in about 25 countries globally. Dental fluorosis is an acquired defect of enamel due to the exposure of an individual to excessive fluoride levels during tooth development. It could result in mild-to-severe discoloration of teeth, which might necessitate esthetic correction. Bleaching is one of

  • Enhancing white and pink esthetics using porcelain laminates in a fluorosis patient

    Fluorosis can cause enamel degeneration to varying extent depending on the fluoride levels prevalent in that particular area. It can range from slight mottling of enamel to severe degeneration leading to demineralization and resultant discoloration. In the latter case, treatment options are limited to bonding of the outer surface of

  • Clinical effectiveness of two microabrasion materials for the removal of enamel fluorosis stains

    This study evaluated the effectiveness of two microabrasion products for the removal of enamel fluorosis stains. Using a split-mouth study design, two operators used PREMA (PM) and Opalustre (OP) to remove fluorosis-like stains from 36 subjects (10-12 years old). Both products were rubbed onto the surface of the affected teeth

  • A minimally invasive procedure for esthetic achievement: enamel microabrasion of fluorosis stains.

    Esthetic alterations (such as fluorosis) that result from intrinsic dental staining in enamel and dentin can be controlled or softened by noninvasive methods such as dental bleaching or enamel microabrasion. Part of the enamel is removed during microabrasion; however, this wear is clinically insignificant and does not harm the dental

  • 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.

  • 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

  • Racial Disparities in Dental Fluorosis

    In 2005, the Centers for Disease Control published the results of a national survey of dental fluorosis conducted between 1999 and 2002. According to the CDC, black children in the United States have significantly higher rates of dental fluorosis than either white or Hispanic children. This was not the first time that black children were found to suffer higher rates of dental fluorosis. At least five other studies -- dating as far back as the 1960s -- have found black children in the United States are disproportionately impacted by dental fluorosis.

  • 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.

  • Diagnostic Criteria for Dental Fluorosis: The Thylstrup-Fejerskov (TF) Index

    The traditional criteria (the "Dean Index") for diagnosing dental fluorosis was developed in the first half of the 20th century by H. Trendley Dean. While the Dean Index is still widely used in surveys of fluorosis -- including the CDC's national surveys of fluorosis in the United States -- dental
