The oral health status, treatment needs, and dental utilization patterns of Native American elders.
The purpose of this study was to evaluate the oral health status, treatment needs, and dental care utilization patterns of a Native American population aged 65-74 years. A random sample of 688 individuals was chosen and approached regarding participation in the study. Data were gathered through an interviewer-administered questionnaire and an oral examination. A total of 204 individuals completed all aspects of the study. Only one participant had all 28 natural teeth, while 58.3 percent were totally endentulous. Of the 85 dentate participants, almost 53 percent required at least one extraction. The average number of required extractions in the dentate subjects was three. Although 94 percent of the sample stated they had a usual source of dental care, 40.7 percent had not visited a dentist within the last five years. Multiple regression analyses were used to determine the factors associated with total number of teeth present among the dentate participants. Years of education and time since last dental visit were the two significant predictors (P less than .05) of number of teeth present. The higher the level of education, the greater the number of teeth in later life. The number of teeth present was inversely related to years since dental treatment. Compared to the results of the National Survey of Oral Health in US Employed Adults and Seniors, this Native American sample had a higher prevalence of endentulism and utilized dental services less often than a comparable age group in the US population as a whole.
