United States Food Law Update

This update summarizes significant changes and developments in food law over the first half of 2005. Not every change in national food law for the first half of 2005 is included; instead, this update is limited to significant changes in national law. New developments in state law, while certainly important and deserving of attention, are beyond the scope of this update. These updates provide a starting point for scholars, practitioners, food scientists, and policymakers determined to understand the shaping of food law in modem society. Tracing the development of food law through these updates also builds an important historical context for the overall development of food law

Sleeping Tongue Posture and Its Relationship to Craniofacial Morphology

Introduction: There exists good consensus in the literature supporting the notion that resting tongue posture is an important factor in dental arch development and maintenance as well as airway control. What has yet to be quantitatively measured is the duration of time that a subconscious, resting tongue posture is maintained and whether such posture differs among various craniofacial morphologies. Quantifiable measurements might allow for prediction of tongue-posture-related problems specific to certain facial types. Purpose: The objective of this study was to record sleeping tongue posture over time in 27 subjects and to compare findings with craniofacial morphology determined by cephalometric and model analysis. Methods: A sample of 27 subjects (11 female, 16 male) slept for three nights each while wearing an intraoral, tongue-posture-monitoring device. Tongue posture indices (TPI) were calculated for each night and compared with vertical and transverse skeletal measurements taken from a lateral cephalograph and plaster study models. Results: Nonparametric correlations demonstrated that average TPI is significantly and inversely correlated with palatal height, ratio of palatal height/palatal width, and lower face height (p \u3c .002, .001, 028 respectively). Independent samples median tests showed that TPI was significantly lower for subjects that snore, breathe through their mouth and nose, and sleep on their back (p \u3c .037, .057, .096 respectively). Conclusions: Variability in sleeping tongue posture exists between people of differing facial morphologies. Sleeping tongue posture also appears to vary depending on sleeping position, breathing modality, and tendency to snore
