OROFACIAL PAIN SUPPLEMENT  
                                 NOTES   
   
    The 1989 Orofacial Pain Data File is derived from data collected
    through the National Health Interview Survey (NHIS).  As part of the
    1989 NHIS, information about basic health-related activities and
    about dental health was obtained from a sample of the civilian,
    noninstitutional population of the United States (116,929 persons).
    Information on orofacial pain was asked of a subsample of the NHIS
    sample:  each unrelated individual (age 18 and over) and one
    randomly selected adult (age 18 and over) from each family.  This
    orofacial pain data file consists of 42,370 data records (one for
    each person who answered the orofacial pain questions).  The data
    record for each of these persons consists of the basic NHIS Person
    data, the dental health data, and the orofacial pain data in the
    following order:
