ABSTRACT

Introduction:

Dentomaxillary Anomalies (DMA) affect the growth and morphology of the stomatognathic system of individuals, representing a public health problem. Few studies have described its prevalence among vulnerable populations in Chile. The aim of the study was to explore the prevalence of DMA and its association to non-physiological habits (NFH) and sociodemographic characteristics among primary school children living in Ercilla, Chile. Material and

Methods:

A convenience sample of 327 primary school students from six schools in Ercilla, were assessed through an intraoral and extraoral evaluation. Overjet, overbite, molar relationship, presence of DMAs, and NFHs were measured. Descriptive statistics, analysis of association between DMAs and studied factors, and logistic regression models were done and odds ratio with 95% confidence intervals presented.

Results:

A total of 61.5% of students presented at least one DMA. Chi-square test showed no significant association between DMA prevalence and NHFs, however, after adjusting for sociodemographic factors, children with NFH were 1.69 (95%CI 1.02-2.78) times more likely to have DMAs. Gender and area of residence were not significantly associated with DMAs.

Conclusion:

In children from Ercilla, DMAs were associated with NFHs, however, sociodemographic characteristics did not have a significant role in the presence of DMA, suggesting that sociodemographic factors might not strongly influence orthodontic needs among children from this geographical area.
RESUMEN

Introducción:

Las anomalías dentomaxilares (ADM) afectan el crecimiento y la morfología del sistema estomatognático de los individuos, lo que representa un problema de salud pública. Pocos estudios han descrito su prevalencia en poblaciones vulnerables en Chile. El objetivo del estudio fue explorar la prevalencia de ADM y su asociación con hábitos no fisiológicos (HNF) y características sociodemográficas en niños de escuela primaria que viven en Ercilla, Chile. Material y

Métodos:

Se evaluó una muestra de conveniencia de 327 estudiantes de educación básica de seis escuelas de Ercilla mediante una evaluación intraoral y extraoral. Se midieron el resalte, la sobremordida, la relación molar, la presencia de DMA y HNF. Se realizó estadística descriptiva, análisis de asociación entre ADMs y los factores estudiados, y modelos de regresión logística y se presentaron odds ratio con intervalos de confianza del 95%.

Resultados:

El 61,5% de los alumnos presentó al menos una ADM. La prueba de chi-cuadrado no mostróuna asociación significativa entre la prevalencia de ADM y HNF, sin embargo, después de ajustar de acuerdo a factores sociodemográficos, los niños con HNF tenían 1,69 (IC del 95% 1,02 a 2,78) veces más probabilidades de tener ADMs. El género y el área de residencia no se asociaron significativamente con las ADMs.

Conclusión:

En los niños de Ercilla, las DMA se asociaron con NFH, sin embargo, las características sociodemográficas no tuvieron un papel significativo en la presencia de DMA, lo que sugiere que los factores sociodemográficos podrían no influir fuertemente en las necesidades de ortodoncia entre los niños de esta área geográfica.
