The purpose of this study was to evaluate the effect of an alcohol-based caries detector (Kurakay) on the surface tension of a conventional sodium hypochlorite (NaOCl) preparation, and a product containing a surface-active agent (Chlor-XTRA). The surface tensions of the following solutions were tested: NaOCl, a mixture of NaOCl and Kurakay 9:1 w/w, Chlor-XTRA, a mixture of Chlor-XTRA and Kuraka...

The aim of this study was to investigate the efficiency of different diagnostic methods in detection of residual dentinal caries in excavated cavities. Fifty extracted molar with deep dentinal carious lesions were excavated using a slow-speed handpiece. All cavities were assessed by laser fluorescence(LF) device, electronic caries monitor(ECM), and caries detector dye(CDD) by three independent ...

Since 1999, our group at the CADIFT, University of Toronto, has developed the application of Frequency Domain Photothermal Radiometry (PTR) and Luminescence (LUM) to dental caries detection. Various cases including artificial caries detection have been studied and some of the inherent advantages of the adaptation of this technique to dental diagnostics in conjunction with modulated luminescence...

The aim of this study was to evaluate the μTBS in different dentin substrates and water-storage periods. Twenty-four dentin blocks obtained from sound third molars were randomly divided into 3 groups: Sound dentin (Sd), Caries-affected dentin (Ca) and Caries-infected dentin (Ci). Dentin blocks from Ca and Ci groups were subjected to artificial caries development (S. mutans biofilm). The softest...

Purpose: This study aimed to evaluate the effects of light-curing method on the marginal seal and resin composite adaptation to the cavity wall, and the formation of enamel cracks around resin composite restorations. Materials and Methods: Cylindrical cavities were prepared on the buccal or lingual cervical region of human molars. The teeth were restored with Clearfil Liner Bond 2 V and filled ...

OBJECTIVE To detect changes in the microbial richness of dental plaque and oral behaviors during caries development in young Chinese children. METHODS Supragingival plaque samples and a survey of oral behaviors of 130 children aged 3 at baseline were analyzed at 6 months and 12 months. Total DNA was isolated from all samples and PCR-denaturing gradient gel electrophoresis analysis was conduct...

The prediction of caries risk has been of long-standing interest. Generally, few of the tests involving oral bacteria or their products have become accepted. Presently, the main focus is on counts of lactobacilli (L) and mutans streptococci (MS). Due to their positive numerical association with human caries and the linkage of this association to carbohydrate consumption, counts of L and MS may,...
