Abstract
In this 2nd part, the current treatment of white spot lesions by erosion/infiltration is presented, beginning with a reminder of the principle of superficial infiltration, which enables most early carious lesions, fluorosis and post-traumatic lesions to be treated. However, this technique has met with frequent failures in cases of MIH or deep lesions of traumatic origin or those associated with fluorosis. For this reason a new deep infiltration technique is proposed: thanks to its global treatment concept, this enables all white spots to be treated. The place of whitening in these treatment options is discussed, with explanations of the main reasons for its failures.

Using microabrasive material to remove fluorosis stains.
BACKGROUND: Increased public access to fluoride has decreased the prevalence of caries and increased the prevalence of fluorosis staining. This article provides a case report involving a conservative method of removing fluorosis stain, as well as describes an in vitro test of the method. CASE DESCRIPTION: A healthy man sought treatment

Effectiveness of bonding resin-based composite to healthy and fluorotic enamel using total-etch and two self-etch adhesive systems
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

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

Resin infiltration for aesthetic improvement of mild to moderate fluorosis: a six-month follow-up case report
Purpose: To determine whether fluorosed areas of teeth can be successfully treated with resin infiltration and whether the results are long lasting. Materials and Methods: For the present case of mild to moderate dental fluorosis, the microinvasive resin infiltration technique was chosen, following suboptimal results of in-office vital tooth bleaching

Resin infiltration technique and fluoride varnish on white spot lesions in children: Preliminary findings of a randomized clinical trial.
AIM: To clinically assess the efficacy of resin infiltration versus fluoride varnish for arresting white spot lesions (WSLs) on permanent teeth in children. Subjects and Methods: Among the children referred to the our University, Faculty of Dentistry, Department of Pediatric Dentistry, 23 aged between 8-14 with 81 anterior WSLs were included

Dental Fluorosis in the U.S. 1950-2004
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

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.

Mechanisms by Which Fluoride Causes Dental Fluorosis Remain Unknown
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
-
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

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
