“…Both types of glass-ionomer cement are capable of releasing fluoride and, despite occasional claims that one or the other type releases more fluoride, they are generally reported as releasing comparable amounts [ 17 , 18 ]. Certainly, there is no fundamental reason why either conventional or resin-modified glass-ionomers should release more.…”

The topic of fluoride release and uptake by glass-ionomer (glass polyalkenoate) dental cements is reviewed. The study was based on a literature search carried out using PubMed. The main key words used were glass-ionomer and fluoride , and further refinements were made by adding the keywords anti-microbial , anti-caries and remineralization . Papers were selected from the initial search, which concentrated on fundamental aspects of fluoride release, including kinetics and the influence of the cement composition, and resulting clinical performance against caries. Other relevant papers were cited where they added useful and relevant data. From these published papers, it was possible to explain the detailed mechanism of fluoride release by glass-ionomer cements and also its uptake. Fluoride release has been shown to be a two-step process. In neutral solutions, the steps can be divided into early wash-out and long-term diffusion. In acid conditions, the early wash-out remains, though with greater amounts of fluoride released, and the long-term release becomes one of slow dissolution. The effect of fluoride on the viability of oral micro-organisms has been described, and glass-ionomers have been shown to release sufficient fluoride to reduce the size and viability of adjacent populations of oral bacteria. The effect of low levels of fluoride on the remineralization of tooth tissue has been considered. Levels needed to increase remineralization are much lower than those needed to adversely affect oral bacteria, from which we conclude that glass-ionomers release sufficient fluoride to promote remineralization. Despite this, there remains uncertainty about their overall contribution to sound oral health, given the widespread use of other sources of fluoride, such as toothpastes.

“…These materials can bond to tooth surfaces by chemical interaction. They are usually composed of alumino-fluorosilicate glass powder that reacts with an aqueous solution of polyacrylic acid (80). Glass ionomers can release several ions, including fluoride, already starting from the setting reaction.…”

The presence of a huge amount of data regarding the onset of a carious lesion in close proximity with a restoration must not make ourselves less aware about the fact that, still, a lot of information is missing about secondary caries formation. Many pieces of information are highly conflicting, such as, for instance, the role that different microbial species have in the onset of the lesion, or the link between the existence -and width -of a gap between hard tissues and restoration, and the development of a secondary lesion, or, again, the clinical decisions regarding the replacement of a restoration due to secondary caries, and, if so, to what point stop excavating? The main difficulty in this field arises from the fact that secondary caries is the result of very complex interactions taking place among already injured human tissues, overlying biofilms that often maintain the dysbiotic conditions that lead to the primitive lesion, and dental materials that may help, or even worsen that situation. Increasing our knowledge about what exactely happens after a material is placed at this three-sided interface may greatly help us in designing new dental materials able to interact in a positive way both with the host and its biofilm, ensuring longevity to restorations and helping in reducing what is nowadays their main cause of failure -secondary caries. Secondary caries: what is it?The answer is: we still do not know for sure. In 2009 Cenci et al. stated: "Up to now, there has been no conclusive evidence for the association or lack of association between gap presence and caries adjacent to restorations." After ten years, this sentence still seems to be valid. However, we must start from some definition (1). Secondary or recurrent caries is a lesion at the marginal area of an existing restoration (2). Contrarily to residual caries, which is represented by infected tissue left behind after cavity preparation, secondary caries develop close to a restoration. Nevertheless, in clinical practice, it is most often difficult to differentiate between these situations. This is the reason why secondary caries have been receiving increasing attention over the last years. It has become a matter of concern in restorative dentistry since it has been recognized as the most common reason for premature failure of restorations, irrespective of the restorative material used (3-5). This fact is demonstrated by a relevant amount of experimental data about the clinical performance of dental restorative materials that have been published over the last two decades (3,(6)(7)(8)(9). In these studies, the development of a secondary caries lesion is considered one of the most important parameters to measure the performances of the restorative materials. Furthermore, recent

“…The proposed benefits of using glass ionomer cement included the lack of need for pretreating the enamel with phosphoric acid to create conditions for mechanical bonding, the release of fluoride over several months, and the possible development of a modified, less cariogenic microflora [14]. The cariostatic effect is mainly attributed to the fluoride release of both glass ionomer and resinmodified glass ionomer cement [15]. It occurred for more extended periods and with greater fluoride release levels than with fluoride-containing composites or compomer cement [15].…”

Glass Ionomers showed an initial burst of fluoride discharge that rapidly declined to levels that are unlikely to have a clinically significant effect on caries inhibition.…”

After Orthodontic treatment, it's just as crucial to restore a healthy and normal tooth structure as it is to achieve the aims of Orthodontics. Orthodontic treatment has the potential to cause some damage to dental enamel. Orthodontists should make every effort to minimize damage to dental tooth enamel. These enamel lesions, such as white spot lesions, are managed first by developing appropriate dental hygiene habits and prophylaxis with topical fluorides, high-fluoride toothpaste, fluoride mouthwashes, gels, varnishes, fluoride-containing bonding materials, fluoride-containing luting cement, and fluorides in elastomers. Other materials and treatments include casein phosphopeptides-amorphous calcium phosphate, probiotics, carbamide peroxide, polyols, sealants, microabrasion, resin infiltration, antiseptics, and lasers, have recently been recommended. This article reviews the current information regarding the various materials used to manage enamel demineralization and promote remineralization during and after orthodontic treatment.
