Effect of fluoride released from restorative dental meterials on hardness of enamel and dentin

Anchana Panichuttra (Chulalongkorn University, 2001)

Nowadays fluoride releasing restorative materials are widely used in an attempt to prevent secondary caries. The purpose of this study was to investigate the effect of fluoride released from different materials on the ...
Interaction of Actinobacillus actinomycetemcomitans with antigen-presenting cells (dendritic cells)

Piyawadee Pothiraksanon, 2512- (Chulalongkorn University, 2002)

It becomes clear that the interaction between dendritic cells (DCs) and pathogens is a significant factor in determining the effectiveness of the immune response and the outcome of disease. Periodontitis is a chronic ...
Activation of matrix metalloproteinase-2 (MMP-2) by supernatant of anaerobic bacteria cultivated from periodontal pockets

Kassara Pattamapun (Chulalongkorn University, 2002)

It has been reported that host-derived enzymes, matrix metalloproteinases (MPs), play a major role in periodontal tissue destruction. The purpose of this study was to examine the effects of bacterial supernatant from mixed ...
The influence of silane coupling agent on hydrolytic durability of silica-contained composite resin determined by flexural properties

Mansuang Arksornnukit (Chulalongkorn University, 2003)

Using silanated filler in making dental resin composite results in the superior performance in both mechanical properties and durability of composite. The objectives of this study were to elucidate the effect of amount of ...
The effect of post and cement types on vertical root fracture resistance in endodontically treated teeth

Chalermkwan Chantarat, 2529- (Chulalongkorn University, 2003)

This in vitro study evaluated the vertical fracture resistance of human extracted maxillary central incisors in six experiment groups. Two different types of luting cement (resin and zinc phosphate cement) and three different ...
Effect of Porphyromonas gingivalis and Actinobacillus actinomycetemcomitans on the mechanism of matrix metalloproteinase-2 activation in human periodontal ligament cells

Siriluck Tiranathanagul (Chulalongkorn University, 2004)

Periodontitis is initiated by specific groups of Gram-negative bacteria. Among them, P. gingivalis and A. actinomycetemcomitans have been strongly supported as etiological agents to induce host responses leading to destruction ...
Comparison of gene expression related to maxillary incisor development between the wild type and the homozygous rsey rats with maxillary supernumerary incisors

Rungarun Kriangkrai, 2516- (Chulalongkorn University, 2004)

This study aims to investigate the developmental process of the maxillary incisor tooth in the wild type SD and in the homozygous rat small eye. Rat small eyes; rSey; is inherited a dominant mutation in Pax-6 gene. The ...
Effects of IL-17 and IFN-gamma on human gingival fibroblasts

Paiboon Jitprasertwong (Chulalongkorn University, 2004)

Periodontitis is a bacterial infection characterized by chronic gingival inflammation, which leads to the loss of tooth-supporting tissues. Dense infiltration of activated memory T cells and high levels of their cytokines ...
