RESUMO
Analysis of Southwestern HHANES data showed that the prevalence of dental caries among Mexican-American children is similar to that of children of the same age examined during the NIDR survey (1979-1980), despite a lower level of restorative treatment. Approximately 50% of Mexican-American children 17 years of age, however, had five or more teeth that were either decayed or filled. Occlusal surfaces of molars were the most susceptible teeth to decay; few anterior teeth were affected. This distribution of dental caries strongly supports the use of fissure sealants on molar teeth. Children from low-income families had two times more decayed teeth than children from high-income families. Mild gingivitis and poor oral hygiene were more prevalent in the Mexican-American children than in the child population for the region examined during NHANES I in 1971-1974. Children from high-income families had better periodontal health than those from low-income families.

This paper describes the estimated prevalence of dental caries and periodontal disease in 2,550 children, 5 through 17 years of age, who resided in five southwestern states of the United States and were examined in the Hispanic Health and Nutrition Examination Survey (HHANES) of 1982-84 of the National Center for Health Statistics. Dental caries in the Mexican American children was predominantly a disease of occlusal surfaces of molars; few smooth surfaces of posterior and anterior teeth were affected by caries. This intra-oral distribution of dental caries strongly supports the use of fissure sealants as a preventive procedure. Filled tooth surfaces contributed about 66 per cent of the total DMFS (decayed, missing, filled surfaces) scores. The analysis also shows that about 50 per cent of the 17 year old Mexican Americans had five or more filled or decayed teeth. Mild gingivitis was prevalent (76.9 per cent) in the Mexican American children.

The Southwestern portion of the Hispanic Health and Nutrition Examination Survey (HHANES) was conducted by the National Center for Health Statistics (NCHS) in 1982 and 1983. The survey population was Mexican-Americans residing in five Southwestern states. This report presents data on the prevalence of total tooth loss, dental caries, and periodontal diseases in 3860 Mexican-American adults aged from 18 to 74. Results show that 4.3% of this group was edentulous. Among the dentate, Mexican-Americans had lower overall DMF scores but higher numbers of untreated decayed teeth than did residents of the same region seen in the NHANES I survey in 1971-1974. Caries of the smooth surfaces in both posterior and anterior teeth was more pronounced in the older than in the younger age groups. Mexican-Americans had more gingivitis but fewer periodontal pockets than did the general population in the Western states during NHANES I. The caries pattern in the Mexican-Americans suggests that caries among adults may remain a problem in the future, with the possibility of increased involvement with the aging, although modest, of smooth tooth surfaces.

The number of DM and d teeth and surfaces was recorded for 220 Yanomamö Indians from three groups of villages with different degrees of contact with Western culture. Specimens of plaque were taken from the teeth, transported in a holding solution, cultured, and examined for specific oral streptococci. In addition, the periodontal health and oral hygiene of one group of villagers were assessed using the Russell PI and the Greene & Vermillions OHIS. Caries experience among the Yanomamö was shown to be positively associated with exposure to Western culture. S. mutans was recovered with about the same frequency from specimens taken from the teeth of Indians living at all three village locations. However, the presence of S. mutans alone did not account for the disparity in dental caries scores. The examinees had abundant and persistent accumulations of soft deposits on their teeth accompanied by markedly inflamed gingival tissues. However, periodontal pockets and loss of appreciable amounts of bone did not appear as early in life nor were they as severe as reported for some other populations which practice little oral hygiene. Those disparities in the distribution of plaque-induced oral diseases between Western populations and the Yanomamö warrant further study.
