OBJECTIVE The growing demand for enhanced esthetic appearance has led to great developments in bleaching products. The exposure of hard tissues of the tooth to bleaching agents can affect the roughness of the enamel surface. The freshly bleached enamel surface exposed to various surface treatments such as fluoride and other remineralizing agents have been assessed in this study. The aim of this...

introduction: to compare the effects of 0.05% sodium fluoride (naf) mouthrinse, gc tooth mousse and gc mi paste plus on white spot formation inhibition. materials and methods: thirty pairs of extracted human premolars were cut in half mesio-distally with a disc. the teeth were coated with nail varnish, except a part of the buccal and/or lingual enamel, which was used as the test area, and then ...

Objectives: The aim of this study was to evaluate the effectiveness of casein and hydroxyapatite on remineralization of white spot enamel lesion and assessment by a new caries detection device, FluoreCam System (Thereametric Co., Indianapolis, USA). Study Design: Demineralized human enamel specimens were measured for baseline surface by the following methods; micro hardness, Quantitative Light ...

BACKGROUND Caries process is not a static one, but is dynamic with interspersed periods of demineralization and remineralization of enamel, intimately related and occurs episodically based upon the presence of cariogenic bacteria in dental plaque and the availability of refined carbohydrates for fermentation to organic acids. OBJECTIVES Early enamel caries could be reversed with avoidance of ...

Methods: Bovine tooth roots were sectioned, mounted in epoxy, and progressively ground and polished to expose the dentin layer. Caries-like lesions were pre-formed in the dentin samples by immersion for 96 hours in demineralization solution (pH = 4.52) at 37°C. Randomly-selected samples were pulled after lesion formation and did not go through the remin/demin cycle. The remaining samples were s...

background: in order to compensate the adverse consequences of bleaching agents, the use of fl uoride-containing remineralizing agents has been suggested by many researchers. the aim of this study was to compare the effect of applying two remineralizing materials on bleached enamel hardness and in comparison to natural saliva. materials and methods: in this experimental study, 30 enamel samples...

Background: This study investigated the effect of three remineralizing agents on improving white spot lesions (WSLs). Material and Methods: This clinical trial included children who had at least one WSL on anterior teeth of upper or lower jaws. The participants were randomly assigned to 4 groups by treatment: 1) a cream containing casein phosphopeptide-amorphous calcium phosphate and fluoride (...

INTRODUCTION NovaMin is a synthetic mineral compound composed of calcium, sodium, phosphorus, and silica. It releases crystalline hydroxyl-carbonate apatite (HCA), which structurally resembles the minerals naturally found in the teeth. Nano-hydroxyapatite (NHA) is a biocompatible compound with high affinity for tooth enamel. NHA particles morphologically resemble dental enamel apatite crystals....
