The group said that edentulism ?will be 30% lower in 2050 than it was in 2010."
The researchers used 5 national cross-sectional health surveys, ranging from 1957 to 2012. More than 150,000 individual adult records were examined during this time.
?Across the 5-decade observation period, edentulism prevalence declined from 18.9% in 1957 to 1958 to 4.9% in 2009 to 2012. The single most influential determinant of the decline was the passing of generations born before the 1940s, whose rate of edentulism incidence (5 to 6% per decade of age) far exceeded that of later cohorts (1 to 3% per decade of age). High-income households experienced a greater relative decline, but a smaller absolute decline, than did low-income households.?
In 2010, high-income families rarely experienced edentulism, which is expected to him a low of 2.6% by 2050.
"While it's encouraging to know that this study by Dr. Gary Slade illustrates a steep decline in U.S. edentulism over the past 5 decades, these health gains in absolute terms have not been distributed equally," said Dr. Timothy DeRouen, American Association for Dental Research President. "Additional public health measures must be taken to reduce tooth loss in low-income populations."
