s Caries Res 2009;43:179–244 187 with MH were prepared by sectioning and polishing. Cross-sectional Vickers hardness of the 600  m thick enamel sections was measured across MH-affected and apparently sound areas and mean hardness values analysed by one-way ANOVA. Subsequently these sections were lapped to 100 m and assessed using polarizing microscopy (PM) and transverse microradiography (TMR)...

Esthetics has been an indispensable element in human life for centuries. The elimination of esthetic problems substantially aids in confident self-expression. In addition to the different departments dealing with esthetics in medicine, orthodontists also make arrangements to eliminate various esthetic and functional concerns. These arrangements include the correction of skeletal and dental anom...

laser irradiation has been suggested as an adjunct to traditional caries prevention methods. but little is known about the cariostatic effect of diode laser and most studies available are on permanent teeth.the purpose of the present study was to investigate the effect of diode laser irradiation combined with topical fluoride on enamel surface microhardness.forty-five primary teeth were used in...

Background and Aim: Carbonated diet soda is the most common etiologic factor for dental erosion, and fluoride products have been proposed as an option for the preven-tion of that problem. This study evaluated the effect of Remin Pro and neutral sodium fluoride on the prevention of dental enamel erosion using profilometry. Materials and Methods: This study was conducted using an experimental-...

A new method for altered enamel surface remineralization has been proposed . To this aim carbonate-hydroxyapatite nanocrystals which mimic for composition, structure, nanodimensions, and morphology dentine apatite crystals and resemble closely natural apatite chemical-physical properties have been used The results underline the differences induced by the use of fluoride ions and hydroxyapatite ...

objective: oral iron drops are recommended for children aged 6-24 months to prevent iron-deficiency anemia. however, their use is associated with the potential risk of erosion and microhardness reduction of primary teeth enamel due to their high acidity. it seems that the combination of silicone oil, nano-hydroxyapatite and chitosan powder may be able to improve the microhardness and surface st...

Enamel and dentin are susceptible to acids from food sources leading dental erosion, a global problem affecting millions of individuals. Particulate hydroxyapatite (HAP) on the tooth surface can influence effects acid attacks. Standardized bovine enamel samples with artificial saliva used in an vitro cyclic demineralization–remineralization protocol analyze structural changes experienced by sur...

Consumption of acidic foods and drinks and other factors that cause enamel wear are responsible for the daily enamel loss and degradation. Use of some toothpastes that have been showed to possess different properties of remineralisation and/or repair of the enamel surface may help to protect tooth enamel. The aim of this study was to evaluate whether the use of toothpaste containing Zn-carbonat...

OBJECTIVE To test and describe the use of various combinations of mechanical and chemical techniques for enamel reduction to obtain a smooth surface. METHODS Bovine teeth (2 surfaces on each of 32 teeth) were used. The teeth were mounted in blocks of dental plaster, which were then mounted in a vise. The mesiodistal enamel contact areas were reduced by various combinations of mechanical and c...
