RESUMEN
Introducción. El objetivo de este estudio es medir la frecuencia e intensidad de las rotaciones en incisivos y caninos permanentes y premolares, superiores e inferiores, y relacionarlas con variables biométricas como anchura intercanina e intermolar, tamaño dentario y discrepancia de longitud de arcada. Material y métodos. Se realizó un estudio observacional retropectivo utilizando modelos de estudio de 50 casos no tratados ortodóncicamente y elegidos al azar. Se requería la presencia de todos los dientes permanente de primer molar a primer molar y la ausencia de agenesias o supernumerarios. Se midieron las rotaciones de cada diente, diámetro mesiodistal, anchuras intercanina e intermolar y discrepancia de longitud de arcada superior e inferior. Para el análisis estadístico se determinó la media, desviación típica e intervalo de confianza del 95% para la media de las magnitudes estudiadas; la prueba de la ABSTRACT
Introduction. The aim of this study is to measure rotation frequency and intensity in upper and lower permanent incisive, permanent canines, and bicuspids, and to relate them to biometric variables such as intercanine and intermolar width, tooth size and arch length discrepancies. Material and methods. Retrospective observation was made using study catss of 50 orthodontically untreated cases selected at random. The presence of all permanent teeth from the first molar to the other was a pre-requesite, as was the absence of agenesis or supernumerary. Measurements of the rotation of each tooth, mesidistal diameter, intercanine and intermolar width, and upper and lower arch length discrepancies were taken. The statistical analysis consisted of determining mean, standard deviation, with a 95% confidence interval for the mean of the values under study. Student T test and ANOVA using Tukey test to compare 2 and 3 means respectively; and r-Pearson correlation coefficient. Results. The percentage of rotated teeth for each type fluctuated between 48$ and 82% with no statistically significant differences between them being found, except for teeth 3.3 and 4.2 which revealed significantly higher frequencies than the remainder. 80% and 82% respectively. No sexual or bilateral dimorfism were found, except for upper arch length discrepancy with a negative value and the number of rotated teeth in the upper arch (r=-0.327; p<0.05)
