Epidemiologic evidence of barometric pressure changes inducing increased reporting of XXXX .

@entity1 @entity158
BACKGROUND AND OBJECTIVE: The daily @entity1 flow at dental emergency departments is subject to fluctuations. The aim of the present study was to investigate whether meteorological parameters were associated with the number of @entity1 reporting acute @entity158 in the oral cavity. METHODS: We performed a retrospective review of all @entity1 presenting with acute oro-dental @entity158 (n=1090) at the dental outpatient clinic in Innsbruck, Austria from January to March 2005. In addition, local weather data were supplied by the Central Institute for Meteorology and Geodynamics Austria. After exponential smoothing of both series of observations, linear regression on the number of @entity1 was performed. RESULTS: Statistical analysis revealed that the acute @entity158 symptoms are not related to the air pressure itself but to the deviation of air pressure. The stronger the daily deviation from the average atmospheric pressure was, the more @entity1 presented with acute @entity158 at the dental emergency department (p=4.2   10(-14)). Our findings implicate that the association of air pressure deviation with variation in @entity1 flow at dental clinics is a consequence of barometric pressure-related @entity158 . CONCLUSIONS: These findings suggest that changes in barometric pressure were the reason for the observed initiation and/or exacerbation of the various oral pains observed in the emergency room setting. This association has been considered to be rare, with most reports suggesting this phenomenon primarily affects divers and aircraft personnel. Our data suggests otherwise, by providing clear evidence that atmospheric pressure changes commonly influences @entity158 .
