dc.description.abstractObjective: To determine the prevalence of shovel-shaped incisors and its association with the overjet in children aged 7 to 11 years of age evaluated clinically in a public institution of Chilca. Material and methods: The sample included 270 children from a Chilca's Public Institution aged from 7 to 11. A clinical assessment was carried out to determine the presence or absence of the shovel-shaped incisors and the type according to the Hrdlička's scale. Likewise, the measurement of overjet was registered with only one periodontal probe PCP 11.5B Hu Friedy®. Finally, the chi-squared test was carried out to determine the association between both variables. Results: The prevalence of the shovel-shaped incisors was 72,60%, more frequently in females It was found a greater prevalence of shovel-shaped lateral incisors (71,85%) than shovel-shaped central incisors (67,77%). In both groups of incisors, the Type I was predominant (31,85% and 31.48%). An association statistically significant between the shovel-shaped incisors and overjet was not found. (p=0.075). Conclusions: The presence of thick marginal ridges with shovel shape increases the volume in vestibule-palatine sense, making possible the inclination of the incisor through the vestibular in order to compensate the thickness of the marginal ridges contact with the inferior incisors. However, such difference of size does not modify significantly the measurement of the overjet.

html.description.abstractObjetivo: Determinar la prevalencia de los incisivos en forma de pala y su asociación con el overjet en niños de 7 a 11 años de edad evaluados clínicamente en una institución pública de Chilca. Material y Métodos: La muestra estuvo conformada por 270 niños de 7 a 11 años de una Institución pública de Chilca. Se realizó una evaluación clínica para determinar la presencia o ausencia de los incisivos en pala y el tipo según la clasificación de Hrdlička. Asimismo, se registró la medida del overjet con una sonda periodontal PCP 11.5B Hu Friedy®. Finalmente, se realizó la prueba de Chi cuadrado para determinar la asociación entre ambas variables. Resultados: La prevalencia de incisivos en forma de pala fue de 72,60% con mayor frecuencia en el género femenino. Se halló una mayor prevalencia de forma de pala en los incisivos laterales (71,85%) que en los centrales (67,77%). El tipo de forma de pala predominante fue el de tipo I en ambos grupos de incisivos (31,85% y 31,48%). No se encontró una asociación estadísticamente significativa entre los incisivos en forma de pala y el overjet. (p=0.075). Conclusiones: La presencia de rebordes marginales gruesos de la forma de pala, aumenta el volumen vestíbulo palatino de la pieza dentaria, haciendo que el incisivo se incline hacia vestibular para así compensar el grosor del contacto de los rebordes marginales con los incisivos inferiores. Sin embargo, dicha discrepancia de tamaño que se presenta, no altera de manera significativa, la medida del overjet.
