Materials scientists drill down vulnerabilities human tooth decay
2020/7/10
Researchers at Northwestern University have cracked one of the secrets of tooth decay. In a new study of human enamel, the materials scientists are the first to identify a small number of impurities t...
The University of Queensland project reduces toddler tooth decay
toddler tooth decay reduces

The answer to early childhood tooth decay could be just a phone call away, thanks to new research by the University of Queensland and Queensland Health.
An in vitro comparison of the force decay generated by different commercially available elastomeric chains and NiTi closed coil springs
Orthodontics corrective Orthodontic appliance design
2009/10/16
This in vitro study was designed to compare the forces generated by commercially available elastomeric chains and NiTi closed coil springs, and to determine their force decay pattern. Forty elastomeri...

In this study the effects of prestressing, environmental acidity, oxygen content, and temperature on mechanical properties were measured for three polyurethane-based orthodontic elastomeric chains...
Orthodontic bone remodeling in relation to appliance decay
Orthodontic bone remodeling appliance decay
2009/1/12
This study examined alveolar bone turnover and orthodontic tooth movement after appliance decay. One group of rats (N=54) received orthodontic force (40 g initial activation) while the other (N=36...
Effect of appliance reactivation after decay of initial activation on osteoclasts, tooth movement, and root resorption
Orthodontic tooth movement Osteoclasts Histomorphometry Alveolar bone Root resorption
2009/1/7
Clinical orthodontists frequently reactivate appliances following decay. Studies of tooth movement and tissue responses following reactivations indicate that linear tooth movement and rapid recruitm...
