Abstract
Fluoride was introduced into dentistry over 70 years ago, and it is now recognized as the main factor responsible for the dramatic decline in caries prevalence that has been observed worldwide. However, excessive fluoride intake during the period of tooth development can cause dental...

Abstract
Fluoride has been used in dentistry for over 100 years for the purpose of preventing dental caries. During this time there has been great debate over the mode of action, the optimum method of delivery, and the potential risks associated with its use. This, the first of three papers, will provide a s...

Abstract
Solutions containing tin and fluoride exhibit remarkable anti-erosive properties with tin ions as a major agent. To elucidate its mechanism of action in dentine, the tin uptake on and in the tissue was investigated and related to histological findings and substance loss. Samples were treated twice d...

Abstract
Dental erosion and the more abrasive dentifrice increased toothbrushing wear on enamel surfaces, while bleaching showed no deleterious effect. Dentin wear also increased after subjection to erosion and use of the more abrasive dentifrice. Bleaching increased surface loss on noneroded dentin and decr...

Abstract
The enamel was significantly harder 25 microm (p = 0.000) and 50 microm (p = 0.001) from the enamel surface in the teeth with brackets bonded with the ACP-containing composite resin as compared with the control teeth. CONCLUSION: ACP-containing orthodontic composite resins may reduce the enamel deca...

Abstract
After six days, treatment with pepsin (group 2) or trypsin (group 3) had no significant influence on mineral loss. The combined impact of pepsin and trypsin led to significantly higher mineral loss (group 4: 202.5+/-37.4) compared to all other groups (group 1: 139.1+/-29.5, p

Abstract
Colour modification of tooth enamel has proven successful, but it is unclear how various bleaching applications affect micro-structural integrity of the whitened enamel. To investigate the internal structural integrity of human intact tooth enamel with the application of two commonly used whitening...

Abstract
Within modern dentistry, a change from invasive to non-invasive strategies for the treatment of dental caries seems to be apparent. The foundation of non-invasive care is old, but is now interpreted differently as a result of new insights. Caries is a dynamic and multi-factorial process that takes p...

Abstract
There have been both large and small changes in operative dentistry in the last 30 years. Extension for prevention is no longer the mantra. The design features of amalgam preparations have moved into the smallest preparations possible to gain full access to the carious dentin. The default Class 2 am...

Abstract
Pulsed CO(2) laser (lambda=10.6 microm) alone was not able to prevent enamel or dentine surface losses due to erosion. Laser treatment in combination with fluoride showed some protection, but the effect does not appear to be synergistic.
