In 2004-2005, 349 of 541 eligible, mostly preschool, children in the Inuvik Region in the Northwest Territories of Canada were examined clinically, and the parents or caregivers of 315 of these children were interviewed to measure their oral health status, and its impacts and determinants. Dental caries is a highly prevalent health problem among these(More)
BACKGROUND The purpose of this review was to investigate evidence for a possible etiological association between oral health and pneumonia or other respiratory diseases. METHODS The following data sources were used: Ovid MEDLINE (In-Process & Other Non-Indexed Citations, Daily Update, and OLDMEDLINE); Cumulative Index to Nursing & Allied Health(More)
This study examined risk indicators and risk markers for periodontal disease experience in 624 adults aged 50 years and over living independently in four communities in Ontario, Canada. The data were collected as part of the baseline phase of a longitudinal study of the oral health and treatment needs of this population. Periodontal disease experience was(More)

Since recent US studies of older adults were conducted in predominantly rural communities, their results may not be generalizable to Canada, where the majority of older adults live in major metropolitan or urban settings. This paper describes a study(More)

Existing data on older adults living independently in East York, Ontario, were reanalyzed and the index was developed using techniques of scalogram analysis. Individuals were scored from 0 to 5 based on their self-reported ability to chew the most(More)

We collected data on the oral health status and treatment needs of a random sample of persons aged 50 years and over. Data on root decay were obtained from the 183 subjects who were dentate. All remaining teeth were examined for root decay and restorations, whether root surfaces were affected by recession or not. Analysis was undertaken by case and root(More)
We undertook two surveys of older adults in Ontario to estimate the proportion in need of dental treatment. Because we expected low response rates, these studies were designed to assess 1) the effect of response enhancement strategies on participation, and 2) the extent of bias in estimates of treatment needs resulting from less than acceptable response(More)
