“…Depending on the fact that acid etching procedure aims to remove the surface layer of incipient caries lesions which has a varying thickness of 40 µm and mineral content of up to 82 vol%, 19 it is possibly acceptable to apply acid etching to remove microabraded superficial enamel The positive effect in masking the white spot lesions by resin infiltration technique has been showed in many in vitro/in vivo studies 17,29 . White spot lesions show an apparently intact surface which is followed by a more porous lesion body underneath and the increased porosity within the lesion body causes the whitish appearence of these lesions 29 . Indeed, light scattering at interfaces between substances of lesion body with different refractive indices (RI), like enamel/apatite (RI 1.62-1.65), water (1.33) or air (1.00), is responsible for the chalky white appearence of enamel lesions.…”

In todays' modern dentistry, the undesirable appearence of dental fluorosis need to be improved to satisfy patients' esthetic requirements in a minimally invasive manner. The approach proposed for the treatment should remove the stained enamel defects, provide blending effect for chalky white appearence and strengthen the enamel against caries development. The purpose of this case report is to present the clinical results of a combined esthetic treatment of a severe fluorosis case with microabrasion, bleaching and resin infiltration. Treatment plan was based on a combined approach of microabrasion, home bleaching and resin infiltration. An improvement in the esthetic appearence was achieved and remained stable in the 6-months follow-up. The technique might be more minimally invasive, less time consuming and cheaper compared to restorative techniques.

“…The data was recorded using computer software(Nexygen-MT; Lloyd Instruments). The shear strength values were then calculated according to the following equation 6 : Shear bond strength = load at failure/surface area of bracket Results:-Surface micro-hardness results:-Surface micro-hardness results measured in Vickers hardness value (HV) for both groups as a function of pH cycling were presented in table (2).…”

“…During the demineralization period there is a dissolution of calcium hydroxyl apatite from the enamel and the production of micro-porosities that result in development of enamel subsurface caries lesions which appear clinically as chalky white and rough patches on the enamel surface denoting active lesions or bright white and smooth spots on the demineralized enamel surface representing inactive lesions. These initial carious lesions can be called white-spot lesions 1,2 .…”

Objective:The aim of this study was to investigate the ability of Icon surface pretreatment to prevent demineralization under and around orthodontic brackets and its subsequent effect on the shear bond strength. Methods: A total number of 20 sound human maxillary premolars freshly extracted for orthodontic treatment were divided into two groups. Group one: control group with no surface pretreatment. Group two: ICON surface pretreatment was done for the enamel surface before bonding the brackets. Both groups were subjected to a 21-day pH-cycling protocol. Shear bond strength measured in mega Pascal (MPa) and surface microhardness measured in Vickers hardness value (HV) were evaluated after thermo-cycling and statistically analyzed. Adhesive remnants index (ARI) scores were determined at 25× magnification and statistically analyzed. Results: there was no significant difference in surface hardness within the study groups; before and after pH cycling as well as no significant difference in shear bond strength in the ICON surface pretreatment group when compared to the control group. Conclusion:ICON surface pretreatment for prevention of white spot lesions can be done clinically under orthodontic brackets without affecting the shear bond strength significantly.Copy Right, IJAR, 2016,.

Understanding the caries process is highly important to establish a proper treatment plan for each patient. Dental caries is a dynamic process involving periods of demineralization and remineralization. During the demineralization period there is a dissolution of calcium hydroxyl apatite from the enamel and the production of micro-porosities that result in development of enamel subsurface caries lesions which appear clinically as chalky white and rough patches on the enamel surface denoting active lesions or bright white and smooth spots on the demineralized enamel surface representing inactive lesions. These initial carious lesions can be called white-spot lesions 1, 2 .

“…The refraction rate for enamel is 1.65 while for water and air it is 1.33 and 1.00, respectively. Higher difference in the enamel-air setup results in a higher dispersion rate [13]. If the white spot appears only after the surface of a tooth was dried up with air, the lesion is small when analyzed with a microscope.…”

Artificially induced demineralization of enamel is frequently used during laboratory tests, particularly in minimally invasive dentistry. The aim of this study was to analyze demineralization techniques of hard tooth tissue applicable in the research of materials in minimally invasive dentistry. The most important factor taken into consideration when designing a method is to make a model as closely similar to the natural environment of the human oral cavity as it is possible. In vitro models allow us to maintain stability and control over the environment and guarantee repeatability of the results. There are main models to produce dental caries outside of the body. The first model is chemical and it uses acids. It is simplified and reflects the actual environment of the oral cavity to a lesser degree. The second model is biological and it is more accurate as it uses microorganisms which build the dental plaque. Among in vitro protocols are also used pH-cycling models. Based on the available literature, it was found that bovine teeth and human teeth with demineralization diagnosed while still inside the oral cavity are the most frequently used kind of specimens in research conducted with use of the chemical model. Not a single case of use of the biological and pH-cycling models were found in the available literature related to the research of infiltrants in minimally invasive dentistry (Adv Clin Exp Med 2015, 24, 5, 891-898).
