Patterns of patient attendance and dental service utilization in northern Labrador 1985-1989

The purpose of the present study was to identify patterns of dental patient attendance and service utilization using both epidemiological and service record data from six satellite clinics in Northern Labrador, Canada, between 1985-1989. Baseline attendances were derived for the region from the analysis of 1985-1988 data, the period prior to the introduction of a non-insured health benefit scheme. The results demonstrated that females and persons under the age of 21 years frequented the dentist the most. The effects of this non-insured health benefit scheme introduced in January 1989, was then compared to the baseline pattern of attendance. This dental coverage removed all financial barriers for dental treatment for a population of Inuit origin in this northern area (or 91% of the population). An increase in the uptake of all dental treatments by 10-40%, and a doubling of fillings and denture treatments was observed. About 7% more patients frequented the dentist in 1989. Attendances of the middle-aged and elderly patients increased by 4%. Mean number of appointments per person per year increased from the baseline level of 1.8 to 2.5. The largest increase in population attendances was observed in Hopedale, while Nain remained the community with the best attendance record. No better monthly patterns of attendance were identified for 1989 compared to the baseline. Future studies should continue to evaluate changes in treatment needs, demands and service utilization in the area on a longitudinal basis. There is also a need for more literature on patterns of dental attendances in northern areas.
