Children living in counties with fluoridated water have significantly less tooth decay than those living in counties that lack water fluoridation programs, according to a newly published large-scale study.
Reduced decay rates were most pronounced in the primary teeth of children living in fluoridated counties. Yet community water fluoridation (CWF) also was credited with conferring a meaningful level of protection to the permanent teeth of children and adolescents. Continue reading
A time-honored preventive dental treatment is getting another look.
A cheap and simple fluoride mouth rinse is highly effective in reducing tooth decay in school children, a recent Cochrane review has concluded.
The paper updates a 2003 review that also showed clear evidence of the decay-inhibiting effect of fluoride rinses. Continue reading
Hispanic medical and dental leaders at a recent joint meeting in Washington, D.C., highlighted the urgency of getting more culturally competent health care services to their communities.
A chronic shortage of Spanish-speaking health care providers has contributed to a lack of access to care and widespread health disparities among Hispanics, they stressed. Continue reading

Section A-A is directed mesio-distally, passing through the larger carious lesion. (C) MicroCT slice of the Villabruna RM3 in correspondence with section A-A.
Scientists studying a decayed lesion within an ancient wisdom tooth say they have discovered the earliest known evidence of dentistry.
The cavitated third molar belonged to a young man said to have lived and died in Northern Italy during the Late Upper Paleolithic era.
Images from inside the 14,000-year-old tooth, obtained using scanning electron microscopy, disclosed a pattern of chipping and striations that researchers say were made using a tiny stone pick. Continue reading
Under the influence of the sugar industry decades ago, federal health officials stepped back from an ambitious campaign to wipe out tooth decay, according to a newly published study.
Researchers from the University of California, San Francisco, analyzed previously unexplored sugar industry documents from the 1960s and early 1970s to reach their conclusions. The paper describing the findings appeared in March in PLOS Medicine.
The documents trace industry interactions with the National Institute of Dental Research (now the National Institute of Dental and Craniofacial Research) during a period when health officials were planning to launch the National Caries Program, an initiative with a goal of eradicating tooth decay within a decade.
