Estimating dental treatment needs among American Indians and Alaska Natives.

OBJECTIVE: This paper describes the treatment needs of the American Indian and Alaska Native (Native American) population estimated from the 1991 Indian Health Service Oral Health Status and Treatment Needs Survey (1991 IHS patient survey). METHODS: The average per capita treatment need for the population is expressed both as the number of dental services and clinical time required to provide these services. Values for service minutes also are used to compare treatment needed with the treatment provided. RESULTS: The need for dental care is greatest among adults aged 25-54 years. We anticipate that needs will increase with population growth and as teeth are retained longer. Large amounts of dental needs go unmet each year in the Native American population: because resources are not available to provide all needed care, dental services are prioritized and rationed. The basic premise upon which care is rationed is changing from basic care for all who have access, to more complex care for fewer individuals. This trend may be driven by the opportunity to generate third party revenue offered by more complex procedures. CONCLUSION: Evaluation is needed of the effects of new approaches on oral health and access to dental care.

A review of the oral health of American Indian and Alaska Native elders.

OBJECTIVES: This paper reviews the demographics, access to care barriers, and the oral health of American Indian and Alaska Native (Native American) elders aged 65 years and older using complete tooth loss as a measure to compare with the US population. Strategies for improving oral health and increasing access to care for Native American elders also are discussed. METHODS: We reviewed the results from patient surveys conducted by the Indian Health Service (1983-84 and 1991) and data from other sources, including the second International Collaborative Study of Oral Health Outcomes (ICS-II) conducted in 1990 on the Sioux and Navajo reservations. We compared complete tooth loss data from these studies with findings of the 1985 National Institute of Dental Research Oral Health Survey of US Employed Adults and Seniors and the Third National Health and Nutrition Examination Survey (NHANES III). RESULTS: The 1991 Indian Health Service (IHS) patient survey reported a complete tooth loss prevalence of 42 percent among elders. Although it is based on a patient sample, this finding is comparable to the rate of 40 percent found among a random sample of Navajo and Lakota adults aged 65-74 years reported in the ICS-II study. The 1991 IHS patient survey also found complete tooth loss among diabetics to be much higher than among nondiabetics. CONCLUSIONS: The prevalence of complete tooth loss for Native American elders is higher than in population surveys of US elders based on random samples. The actual prevalence of complete tooth loss is probably even higher in Native American elders because estimates presented in this paper are clinic based.

A comparison of dental caries experience in Native American and Caucasian children in Oklahoma.

OBJECTIVES: In 1989 the Oklahoma Area Indian Health Service conducted an oral health survey of children attending public schools in Oklahoma to determine the extent of caries experience in the Native American population. Results were to be used to establish program priorities, gather baseline data, and compare the oral health status of Native American children with their non-Indian peers. METHODS: A total of 934 elementary schoolchildren 5-6 years of age were examined along with 733 high school students 15-17 years of age. The study was designed so that approximately 50 percent of the students examined were Native American. RESULTS: The mean dmfs for the 5-6-year-olds was 5.06 for the Caucasian children and 10.35 for the Native American children, a statistically significant difference (P < .001). For the 15-17-year-olds the mean DMFS for the Caucasian students (5.99) was significantly lower (P < .001) than the mean DMFS for the Native American students (10.12). CONCLUSIONS: The prevalence and severity of caries in these Native American students appear to be substantially higher than in their non-Indian peers residing in the same communities. Further study is needed to identify factors contributing to these demonstrated differences in caries experience.

Dental manpower planning in the Indian Health Service.

As a public health agency, the Indian Health Service (IHS) must plan for the needs of the entire American Indian and Alaskan Native (AI/AN) population and distribute resources as equitably as possible. To facilitate this process, the IHS has developed a manpower planning model to provide for the distribution of dental providers based upon the dental needs of the AI/AN population and within the limits of annual appropriations of funds. This paper briefly describes the original IHS Dental Program manpower planning model and the development of modifications over time. The need-based approach to manpower planning developed by the IHS Dental Program has exhibited utility and flexibility over time. It allows a determination of clinic size (number of operatories) and dental staffing requirements, and may be generalizable to other public health programs if an accurate assessment of utilization rate and treatment need can be made for the defined population. Nonetheless, the availability of resources in public programs is subject to the compromises inherent in the political process; thus, the use of a manpower planning model alone may not be sufficient to ensure the equitable distribution of dental resources and dental providers.

Infection control in the Indian Health Service Dental Program: estimated costs and effects on productivity.

The dental literature contains many recommendations defining standards for infection control. Little information is available, however, documenting the cost of implementing these standards. This article describes the cost incurred by the Indian Health Service Dental Program in the Oklahoma area between 1985 and 1988 for infection control. During this period, comprehensive infection control recommendations were published for oral health programs serving Native Americans and data were collected on supply utilization. While productivity data were collected for that same time period do not support the premise that infection control practices lead to decreased clinical productivity, infection control supply costs did increase over fourfold during this period.

Assessment of a dental disease prevention program after three years.

This assessment compared routine data on selected clinical services provided within the Oklahoma City Area of the Indian Health Service during the first six months of fiscal year 1984, prior to implementation of a program emphasizing oral health promotion and disease prevention, to comparable data from 1987. The assessment revealed: similar absolute numbers of routine examinations and completed treatment among children; a 10 percent increase in total visits for persons of all ages, accomplished with comparable numbers of dental personnel; and an increase in the percent of services that were preventive, as well as a concomitant decrease in basic restorative services. The ratio of pit and fissure sealants to one-surface amalgam restorations was reversed dramatically. Although counts of services rendered do not measure oral health status directly, some conclusions are warranted. Clinical dental personnel can be reoriented to devote an increased proportion of available patient care time to primary preventive services, accomplishing a substantial increase in these services. That increase is associated with a corresponding decrease in the proportion of basic restorative services.
