Despite numerous studies and reports documenting the unmet oral health needs of people with disabilities, there has been no systematic national surveillance of oral health among people with disabilities in the United States. This article provides much-needed state-by-state and national epidemiologic data regarding the oral health of people with disabilities.
Special Olympics (SO) athletes in many parts of the world were reported to have poor oral health and high unmet treatment needs. This study was carried out to determine the oral health condition and treatment needs of SO athletes in Nigeria and to suggest ways of improving access to oral healthcare. Consenting athletes who participated in SO events in Nigeria from 2007 to 2008 received oral examination and evaluation by trained volunteers, using standardized Special Smiles screening forms and procedures designed for the event. A total of 1,286 athletes aged 3 to 71 years, 480 (37.3%) females and 806 (62.7%) males, participated in the screening. The majority (86.1%) cleaned their mouths once daily, 12.2% complained of pain, 21.1% had untreated decay, 6.6% had dental injury, 48.1% had gingival signs suggestive of periodontal disease, 15.8% required urgent treatment, and 43.7% required non-urgent treatment. We found that the oral health of SO athletes in this study was poorer than that of the general population in Nigeria.
The endemic Hawaiian genus Brighamia (Campanulaceae) comprises two federally endangered, morphologically similar species, B. insignis from Kaua`i and Ni`ihau and B. rockii from Moloka`i. To assist the design of conservation management programs for these taxa, isozyme analyses were performed to assess the levels of genetic diversity at the population and species levels, including comparisons within and among seven natural populations and one ex situ collection each of B. insignis and B. rockii. Our sampling (N = 80) represents ~41% of all known individuals in the wild. Isozyme analyses revealed levels of genetic variation comparable to those reported for other Hawaiian flowering plant taxa but low levels of genetic variation at the population and species levels when compared to flowering plants in general. Ex situ individuals (N = 61) were genetically representative of natural populations and hence may appropriately serve as stock for population augmentations. The two morphologically similar Brighamia species were highly distinct genetically. The combination of morphological and ecological similarity with allozymic dissimilarity observed in Brighamia is unique among the Hawaiian taxa studied to date.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
