We investigated the treatment effect of non-invasive infiltration on early caries caused by different degrees of enamel demineralization. Forty specimens of early enamel caries were prepared and divided into low and high demineralization groups. After treatment with non-invasive infiltration, the specimens were placed under cariogenic conditions. Color measurements were determined using a spect...

Enamel structure is of importance in demineralization. Differences in porosity in enamel effect the rate of demineralization, seen between permanent and deciduous teeth. Individual differences have been shown in the mean mineral concentration values in enamel, the role of this in demineralization is not thoroughly investigated. The aim of this study was to study variations of depths of artifici...

In contrast to biomineralization phenomena, that are among the most widely studied topics in modern material and earth science and biomedicine, much less is systematized on modern view of demineralization. Biomineralized structures and tissues are composites, containing a biologically produced organic matrix and nano- or microscale amorphous or crystalline minerals. Demineralization is the proc...

OBJECTIVES The aim of this in vitro study was to compare the efficacy of Amorphous Calcium Phosphate (ACP)-containing orthodontic composite and resin-modified glass ionomer cement (RMGIC) on enamel demineralization adjacent to orthodontic brackets evaluated by a new laser fluorescence device. METHODS Sixty extracted maxillary premolars were used in the present study. Twenty orthodontic bracke...

This study aimed to explore the effect of fluoridated toothpastes on biofilm architecture and enamel demineralization in an in vitro biofilm model. Streptococcus mutans was grown on enamel and treated with slurries of commercial toothpastes, containing SnF2 or NaF. Water and chlorhexidine were used as negative and positive controls, respectively. The developed biofilms were imaged and enamel de...

Dental caries is a multifactorial disease caused by the interaction of dietary sugars, dental biofilm, and tissue host. It results from repeated cycles demineralization remineralization at interface biofilm tooth surface. Demineralization process removing mineral ions hydroxyapatite crystals in hard tissues, such as enamel, which can lead to if left unchecked. The reverse lost that occur during...

Tooth and bone specimen require extensive demineralization for careful analysis of cell morphology, as well as gene and protein expression levels. The LacZ gene, which encodes the ß-galactosidase enzyme, is often used as a reporter gene to study gene-structure function, tissue-specific expression by a promoter, cell lineage and fate. This reporter gene is particularly useful for analyzing the s...

INTRODUCTION Enamel demineralization is an undesirable side effect of orthodontic treatment with fixed appliances. The purpose of this in-vitro study was to evaluate the efficacy of applying a light-cured filled sealant onto the buccal tooth surfaces to prevent demineralization. METHODS Fifty extracted human third molars were allocated to 1 of 5 groups: (1) enamel surface untreated (control);...

Quantitative Light-Induced fluorescence (QLF) has been widely used to detect tooth demineralization indicated by fluorescence loss with respect to surrounding sound enamel. The correlation between fluorescence loss and demineralization depth is not fully understood. The purpose of this project was to study this correlation to estimate demineralization depth. Extracted teeth were collected. Arti...
