RESUMEN
Three hundred seventy-one second graders in rural public schools were evaluated for thumbsucking, rest and swallow postures of the tongue, and articulatory placement and acoustic aspects of /s,z/. Significant relationships were observed between thumbsucking and lower dental or interdental rest and swallow postures as well as acoustic errors for /s,z/. The implications of these relationships are discussed.

A biracial sample of two-hundred ninety-six children were assessed for open-mouth posture (OMP) in the natural environment. In addition, rhinometry was performed on 288 of the youngsters. Means were computed for percent OMP and cross-sectional nasal airway. Results indicated that in general these children exhibited relatively high rates of OMP. Boys displayed significantly greater OMP than girls. However, children exhibiting OMP on 80% of the observation intervals had significantly smaller cross-sectional nasal areas than the youngsters who displayed OMP on fewer than 20% of observation intervals. The implications of the findings were discussed.

One hundred and thirty-three second graders in rural public school were assessed on a number of dental, skeletal, and oral muscle function measures. Correlational analyses were conducted in order to determine whether specific myofunctional variables were associated with dentofacial development. Significant relationships were observed between open mouth posture and a narrow maxillary arch and long facial height. Labial and lingual rest and swallow patterns were also related to poor coordination of lip and tongue movements.

Open mouth posture and maxillary arch width were assessed annually for 4 years in a group of children. While younger children exhibited high levels of open mouth posture, this behavior decreased significantly over time. Racial and sex differences, as well as a race-by-time interaction were also evident. The children displayed a significant increase in maxillary arch width across time with sex and racial differences in this growth pattern. Subjects were classified as exhibiting primarily open mouth or closed mouth posture. Although both groups showed increased maxillary arch widths over time, the closed mouth subjects showed significantly greater maxillary arch growth.

A large biracial sample of children were assessed for open mouth posture and maxillary arch width once a year for 3 years. Analyses revealed that although the youngsters exhibited open-mouth posture at high levels, over time, there was a significant decrease in this behavior. Racial and gender differences, as well as a race-by-time interaction, were also evidenced. The children displayed a significant increase in maxillary arch width across time, with gender and racial differences seen in this growth pattern. Finally, when the youngsters were classified as exhibiting primarily open-mouth or closed-mouth posture, it was observed that children with open-mouth posture displayed a significantly slower pattern of maxillary growth compared with children who display anterior lip seal posture. The implications of the findings were discussed.

One hundred thirty-three rural second graders were evaluated for diadochokinetic abilities and myofunctional variables. Single-syllable diadochokinetic rates were significantly correlated with open-mouth resting postures. Slow trisyllable diadochokinetic rates were significantly correlated with a dentalized resting tongue posture and dentalized swallow patterns. The implications of these relationships are discussed.

A biracial sample of 348 elementary school children who were in the first grade were assessed for open-mouth posture (OMP) in the natural environment. In addition, rhinometry was performed on 296 of the children. Means were computed for percent OMP and cross-sectional nasal airway. Results indicated that, in general, these children exhibited relatively high rates of OMP. Boys displayed significantly greater OMP than girls, and black children showed significantly larger cross-sectional nasal areas than white children. A significant correlation between OMP and nasal area only was evident for children exhibiting OMP during more than 80% of the observation intervals. The implications of the findings were discussed.
