Traditionally, caries clinical trials of oral care products have focused on the prevention of caries in children and adolescents at the "cavitation" level. Because of a general reduction in caries incidence and the use of positive control comparators, studies have grown both in size and duration to improve statistical power. Currently, they tend to be of 2 to 3 years' duration, with up to 2,000 high-risk individuals per group. During the past decade, there has been a shift in emphasis from a restorative approach to the treatment of dental caries to a therapeutic approach focused on the remineralization of early caries lesions. However, caries clinical trials of oral care products have not often reflected this paradigm change. This manuscript reviews alternative caries clinical trial methods for oral care products. It is concluded that methods focused on the detection and monitoring of enamel caries and root caries, by visual approaches such as ICDAS and instrumental methods such as QLF, Diagnodent, and Electrical Caries Monitors, provide viable alternatives to traditional methods. In particular, such approaches more accurately reflect the modes of action of many therapeutic agents and formulations and may reduce the cost and duration of product innovation. Source

Models of the vane-cup and Couette rheometers are compared using computational fluid dynamics as well as approximate solutions. Thixotropy of the fluid is incorporated by means of a model based on experimental data for various toothpastes. Parameters of the model are calculated by fitting the results of step-shear tests in Couette geometry and are subsequently used to predict torque for similar tests in vane-cup geometry. Calculations for the thixotropic model were compared to the calculations for a time-independent equilibrium model with the same steady-shear rheology. There are two important findings in this work. First, at constant angular velocity, torque in the vane-cup rheometer for the thixotropic model turns out greater than for the equilibrium model, because the structure of the thixotropic fluid has not had enough time to reach equilibrium. This has implications for rheometry and the modeling of mixing operations. In both cases, torques may be underestimated if the standard equilibrium model is used in calculations. The second finding is relevant to rheometry. As is well known, equilibrium model predicts a lower torque value for a vane-cup geometry than for an equivalent Couette geometry. We found that taking thixotropy into account either makes the difference less pronounced or in some cases actually makes torque for vane-cup higher than for Couette. End effects are also analyzed. © 2010 Elsevier B.V. All rights reserved. Source

An aqueous cleansing composition comprising a cationic surfactant, a nonionic surfactant, and a thickener comprising an alkoxylated methyl glucose ether, wherein a weight ratio of cationic surfactant to nonionic surfactant is greater than 0.9:1. The combination of the cationic:nonionic surfactant ratio with the alkoxylated methyl glucose ether thickener provides the composition with cold weather stability. Cold weather stability is observed when the composition remains transparent after cold storage.

An oral care implement comprises a head with a plurality of cleaning elements, the head comprising a chamber. The oral care implement may include a reflective or refractive membrane positioned within the chamber. A light source may also be positioned within the chamber such that light from the light source is directed at the reflective or refractive membrane. The oral care implement may also include a head plate with a plurality of tooth cleaning elements coupled thereto, the head plate positioned over the chamber. The light from the light source may be emitted through the head plate. In some embodiments the oral care implement may be a toothbrush. In other embodiments the oral care implement may be non-toothbrush type implements that include a body forming a chamber within which the lighting components are positioned.
