Sealants
Both NHANES 1988-1994 and 1999-2002 include sealant
variables for each tooth. Sealant variables follow the naming schemes of the
coronal caries tooth call variables in each survey.
The NHANES 1988-1994 sealant variables code presence of sealants at the tooth
level.
The NHANES 1999-2002 sealant variables contain a string of codes indicating
sealants on each permanent or primary surface.

Variables for presence and number of sealants on permanent
teeth were calculated from these variables for the MMWR Surveillance Summary.
Versions were calculated for all permanent pit-and-fissure teeth and by tooth
type (lateral, premolar, 1st molar, 2nd molar).
(See programs nh3seal.sas and
ohdseal.sas)
The calculated variables are named with the following prefixes:
OHXSEAL (presence of sealants)
Sealn (number
of sealants)
And these suffixes:
Per (permanent)
Lat (lateral)
Pre (premolar)
1st (1st molar)
2nd (2nd molar)
