dc.description.abstractThe purpose of this study was to assess the presence and the degree of expression of the molar tubercle according to sex, dentition and hemi-arches. Study casts of 126 patients were assessed, and those were under orthodontic treatment at the University of Franca, UNIFRAN; they were from both sexs, from 4 to 13 years old. The upper second primary molars and the upper first permanent molars, from both sides, were evaluated regarding the presence and the degree of expression of the molar tubercle. For an association study, the qui-square test was utilized. The concordance about the presence or absence of the molar tubercle according to dentition, hemi-arch and sex, was estimated by the Kappa Statistics. There was a sexual dimorphism concerning the presence/absence of the molar tubercle (p=0.009), however there was no significant association between the degree of expression of the tubercle and the sex (p=0.791). The molar tubercle was more frequently observed in the male sex, in upper second primary molars and in the form of depression. There was a significant and "moderate" concordance between the left and right sides in primary dentition (k=0.596), there was a "good" concordance in permanent dentition (k=0.708) and a "weak" and significant concordance between the presence of the molar tubercle and dentition (k=0.207).en
dc.description.abstractEl objetivo de este estudio fue evaluar la presencia y el grado de expresión del tubérculo molar de acuerdo con el sexo, dentición y hemiarcos. Fueron evaluados modelos de estudio de 126 pacientes que estaban bajo tratamiento ortodóntico en la Universidad de Franca, UNIFRAN, de ambos los sexos, de 4 a 13 años de edad. Los segundos molares superiores primarios y primeros molares superiores permanentes, de ambos los lados, fueron evaluados cuanto la presencia y el grado de expresión del tubérculo molar. Para estudio de asociación, se utilizó el test de Qui-cuadrado. La concordancia de la presencia o ausencia del tubérculo molar segundo dentición, hemiarco y sexo fue estimada por la Estadística Kappa. Se observó dimorfismo sexual cuanto la presencia/ausencia del tubérculo molar (p=0,009), todavía no hubo asociación significativa entre el grado de expresión del tubérculo y el sexo (p=0,791). El tubérculo molar fue más frecuentemente observado en el sexo masculino, en segundos molares primarios y en la forma de depresión. Se verificó concordancia significativa y “moderada” entre los lados derecho e izquierdo en la dentición primaria (k=0,596), “buena” en la dentición permanente (k=0,708) y concordancia “débil” y significativa entre la presencia del tubérculo molar y el tipo de dentición (k=0,207).es
