For many years, glass-polyalkenoate cements have been described as possessing the unique properties of self-adherence to human hard tissues, such as bones or teeth. However, direct experimental evidence to prove the existence of chemical bonding has not been advanced. X-ray Photoelectron Spectroscopy (XPS) was used to analyze the chemical interaction of a synthesized polyalkenoic acid with enam...

Hydroxyapatite nanocrystals in natural form are a major component of bone--a known piezoelectric material. Synthetic hydroxyapatite is widely used in bone grafts and prosthetic pyroelectric coatings as it binds strongly with natural bone. Nanocrystalline synthetic hydroxyapatite films have recently been found to exhibit strong piezoelectricity and pyroelectricity. While a spontaneous polarizati...

Healthy teeth are a vital and visible component of general well-being, but there is little systematic evidence to demonstrate its effect on labor market outcomes. In this paper, we examine the nature and magnitude of the effect of oral health on labor market outcomes by exploiting variation in access to fluoridated water during childhood. The politics surrounding the adoption of water fluoridat...

The effect of Aloe vera on the reduction of plaque and gingivitis was evaluated in a randomized, parallel and double-blind clinical trial. Subjects were randomly allocated to the test group (n=15) - dentifrice containing Aloe vera - or the control group (n=15) - fluoridated dentifrice. Plaque index (PI) and gingival bleeding index (GBI) were assessed at days 0 and 30. Subjects were asked to bru...

A major drawback to clinicians prescribing and patients using chlorhexidine rinse is the development of extrinsic staining. In order to assess the effectiveness of a whitening dentifrice in controlling chlorhexidine stain, fifty-seven subjects rinsed with chlorhexidine twice daily while brushing twice daily with either fluoridated whitening or a fluoridated regular dentifrice. Stain was assesse...

In recent years, resin-based fluoridated sealants have been introduced, the fluoride intended as a cariespreventive ingredient. Studies of prophylaxis pastes containing glycerine or fluoride that attribute poor retention to an impervious layer produced by the fluoride and other ingredients 1, 2 have been discounted by Bogert and Garcia-Godoy3 and Koch et al. 4 using newer generations of bonding...

Bleaching merupakan prosedur pemutihan gigi yang pada saat ini banyak diminati oleh masyarakat. Salah satu efek bleaching adalah terjadinya peningkatan porusitas email sehingga lebih rentan terhadap karies. Remineralisasi diperlukan untuk meningkatkan kekerasan email, salah satunya dengan pemberian pasta gigi. Terdapat beberapa jenis beredar di pasaran, namun belum diketahui manakah terbaikuntu...
