• Abstract

  The laser use in dentistry deserves to be explored in its potential. Some parameters have not yet been assessed for its effect on the interaction between dentin and aesthetic materials, whether direct or indirect. This study aims to assess the influence of Er:YAG laser temporal width pulse on the constituents of the adhesive interface in dentin and in Y-TZP zirconia. This project includ...

• Abstract

  The aim of this study is to investigate the effect of different Er: YAG laser (Super Short Pulse-SSP) parameters in sound and artificial caries-affected dentine. The flattened occlusal dentin of 275 human unerupted molars will be protected with acid resistant varnish in half of the occlusal surface (sound dentin - control) and on the other half caries affected dentine will be produced b...

• Abstract

  The aim of this in vitro study is to obtain standard caries affected-dentine by dentine demineralization process induced by Streptoccocus mutans biofilm (nicrobiological approach). The method validation will be performed by optical coherence tomography, visual inspection, laser fluorescence (DIAGNOdent) and digital intra-oral radiography (DIOR). As all methods do not destruct samples, a...

• Abstract

  This project aims to analyze the effects of thermal aging on the roughness and color of glass ionomer cements. This study will test two variation factors: type of glass ionomer cement (conventional and resin modified) and aging protocol (with and without thermal cycling), with a total of 4 groups (n = 10). It is emphasized that the roughness and color tests will be performed on the same...

• Abstract

  The minimally invasive approach claims for the detection and treatment of early caries lesions. Resin infiltrant materials can penetrate into porosities of body of the lesion by capillary forces, preventing the progression of white spot lesions, improving esthetic and providing support to enamel. It is suggested that Optical Coherence Tomography (OCT) could assess penetration depth of t...

• Abstract

  The new approach to the treatment of dental caries in a clinically relevant features substrate - the dentine affected by caries, that is demineralized, but being capable of remineralization, should be maintained in the floor cavity. Often, the adhesion is performed on this tissue, which has different characteristics of healthy female dentin and consequently the hybrid layer formed with ...

• Abstract

  This in vitro study aims to characterize and compare natural and artificially obtained caries-affected dentin and to determine its role on hybrid layer formation. In the first phase, in forty human molars natural caries-affected dentin (ICDAS) and artificially obtained by a S. mutans biofilm challenge will be compared to sound dentin. These substrates will be characterized and compared...

• Abstract

  The in vitro study will investigate new dentin and enamel surfaces etching strategies and surface biomodification/reinforcement for effective placement of adhesive restorations, shifting into biomimetic approaches to restore the remaining tissue structure and evaluated over time. In the first phase, sixty-four human molar will be prepared and etching with glycolic acid or lactic acid (t...
