Component Description

NHANES is critical for monitoring oral health status, risk indicators for disease, and access to preventive and treatment services. This component will address public health significance in areas of surveillance, prevention, treatment, dental care utilization, health policy, evaluation of Federal health programs, standardization of new methods, and oral health disparities. The purpose of this component is to assess the prevalence of oral conditions and diseases, such as edentulism, denture use, dental sealants, and dental caries. A concurrent set of questions administered during the household interview assesses issues related to oral health quality of life.

Surveillance data was collected on dental caries and sequelae for NHANES using a person-based screening method.
This method, known as Basic Screening Examination (BSE), differed from previous NHANES oral health protocols because it did not assess each tooth surface and the assessments are not made by a dentist. NHANES used a simplified screening process to collect information on untreated caries, dental restorations, and dental sealants. The protocol was applied to all examined persons 5 years or older, and was conducted by a health technologist (HT) rather than a dentist. In addition to performing the BSE, the HT inquired about the use of dentures, performed a tooth count, and ascertained the number of occlusal contacts using existing NHANES protocols.

The NHANES Oral Health Component is a collaborative effort between the National Center for Chronic Disease Prevention and Health Promotion, Division of Oral Health (NCCDPHP/DOH), and the National Center for Health Statistics (NCHS).

Eligible Sample

Participants aged 5 years and older were eligible for the Tooth count and BSE. Additionally, persons aged 25 years and older were eligible for a brief denture questionnaire and functional contacts assessment.

Protocol and Procedure

The oral health subcomponents for the examination component for participants are as follows:

1. A Denture Questionnaire used to assess denture wear for participants age 25 years and older.

2. A Tooth Count used to assess the number of teeth for participants age 5 years and older.

3. A Basic Screening Exam used to asses the presence of at least one tooth with dental decay; at least one tooth with a dental restoration; and at least one tooth with at least one dental sealant for participants age 5 years and older.

4. A Functional Contacts Assessment for participants age 25 years and older.

5. Recommendation of Care findings for participants age 5 years and older.

Quality Assurance & Quality Control

The quality of data in this survey was controlled by (1) an intense training period for the health technologists who were assigned to conduct the oral health examinations with calibration of OH examiners prior to the beginning of the survey, (2) periodic monitoring and recalibration of OH examiners, and (3) periodic retraining of OH examination teams. The reference examiner visited each team three times per year to observe field operations and to replicate 20 to 25 OH examinations during each visit. The purpose of these “expert replications” was to determine if the field examiners were maintaining the examination standards achieved during training and to measure the degree of deviation, if any, from those standards.

If the inter-rater correlation was not within acceptable limits, retraining was conducted on site and future monitoring of the field examiner was intensified. An annual retraining session, for each dental examiner, was also conducted by the reference examiner to reinforce existing protocols and to accommodate protocol updates as needed. All OH training, calibration, and field replicate exams were conducted by the NHANES survey expert dentist.

Automated data collection procedures for the survey were introduced in NHANES 1999. In the mobile examination centers (MECs), data for the oral health component were recorded directly onto a computerized data collection form.

The computer system is integrated and it allows for ongoing monitoring of much of the data. As part of an on-going quality control practice, all data are reviewed systematically for logical inconsistencies and examiner error. Internal quality control data reviews indicate that data quality is acceptable.

Data Processing and Editing

A limited number of hard edits were employed in the OH Examination. For example, if an examiner identified all teeth as missing during Tooth Count, then information for the BSE and Functional Contacts were automatically filled in with “9’s” (cannot assess).

Analytic Notes

Data for this release (2007-08) should only be combined with oral health data from the 2005-06 data cycle for analysis purposes.

The analysis of NHANES oral health data must be conducted with the key survey design and basic demographic variables. The NHANES Household Questionnaire Data Files contain demographic data, health indicators, and other related information collected during household interviews. They also contain all survey design variables and sample weights for these age groups. Other household questionnaire and oral questionnaire files may be linked to the oral health examination data file using the unique survey participant identifier SEQN.

Additionally, the NHANES Household Questionnaire Data Files contains information for an oral health questionnaire inquiring about dental utilization and oral health related quality of life.

Please refer to the NHANES Analytic Guidelines and the on-line NHANES Tutorial for further details on the use of sample weights and other analytic issues. Both of these are available on the NHANES website.
