ABSTRACT

Los análisis de predicción en dentición mixta, posibilitan determinar, aún antes de la erupción de caninos y premolares permanentes, el espacio necesario para éstos dentro del arco dental, facilitando un diagnóstico precoz y planificación adecuada del tratamiento. El propósito de este estudio fue determinar la confiabilidad y validez de dos métodos de medición de los diámetros mesio-distales de piezas dentarias primarias de arcos dentarios inferiores. La muestra estuvo compuesta por 80 niños de 6 – 8 años, concurrentes a la Cátedra de Odontopediatría de la FOUNNE, a quienes se les realizó historia clínica, impresiones y modelos de estudio. Las mediciones se realizaron en boca (método directo) y en modelos de estudio (método indirecto), utilizando en ambos casos, un compás de punta seca. Los resultados obtenidos no arrojaron diferencias significativas, demostrando que ambos métodos poseen igual grado de validez y confiabilidad.


The predictive analysis for mixed-dentition allows us to determine, even before the eruption of permanent canines and premolars, the space these teeth will need within the dental arch, thus facilitating an early diagnosis and adequate treatment planning. The aim of this study was to determine the reliability and validity of two methods that measure the mesio-distal diameters of primary teeth in the lower dental arch. The sample was formed by 80 children treated at the Pediatric Dentistry Department of the FOUNNE and whose ages range between 6 and 8. Their clinical records, dental impressions and study models were prepared. The measurements were taken in mouth (direct method) and in study models (indirect method), using drypoint compass in both cases. The results did not show significant differences, which demonstrates that both methods are equally valid and reliable.
