ABSTRACT
The study investigates the presence of sexual dimorphism in the size of the permanent teeth among Chilean individuals. Mesiodistal and bucolingual diameters were measured in the teeth of 150 patients between 18 and 24 years old, 67 males and 83 females (excluded were third molars and pieces with large cavities and fillings). The largest were found in males; the differences in mean bucolingual diameters with p<0.05 were observed in pieces 1.1, 1.2, 1.3, 1.6, 1.7, 2.6, 3.3, 4.1, 4.2, and 4.5; and with p <0.01, the relevant pieces were to 4.4 and 4.7. With regard to mesiodistal dimensions, the only significant difference p <0.05 was found in piece 1.2. These results show that sexual dimorphism can be found in all group teeth.
RESUMEN
Se investiga la presencia de dimorfismo sexual en las dimensiones de las piezas dentarias permanentes, en individuos chilenos. Se midieron los diámetros mesiodistales y buco linguales de las piezas dentarias de 150 pacientes, de entre 18 y 24 años de edad, 67 hombres y 83 mujeres, se excluyeron los terceros molares y las piezas con caries y obturaciones extensas. Las mayores dimensiones se encontraron en hombres, diferencias significativas en los diámetros bucolinguales con p<0.05 resultaron en las piezas 1.1, 1.2, 1.3, 1.6, 1.7, 2.6, 3.3, 4.1,4.2 y 4.5 y con p<0.01 para las piezas 4.4 y 4.7. Con respecto a las dimensiones mesiodistales, la única diferencia significativa con p<0.05 se encontró en la pieza 1.2. Estos resultados muestran que es posible encontrar dimorfismo sexual en todos los grupos dentarios.
