摘要
The purpose of this work was to study the morphology and morphometry of the mental foramen (MF), as well as to evaluate its morphological configuration; in addition to taking measures of its localization using as a parameter the distances of the foramen to the inferior border of the mandible and at the alveolar ridge. 80 dry mandibles were analyzed using the test of Qui-square and T test, with 5% of significance. Its average distance, on the right side, at the inferior edge of the mandible (IEM) was of 12.96(㊣1 .57) mm and of the alveolar ridge (AR) was of 12.82(㊣3.4) mm. On the left side it was found distant of IEM 12.96(㊣1.32) mm and of the AR 12.82(㊣ 3.22)mm. The largest horizontal diameter found was of 3.32 (㊣ 0.91) mm to the right and 3.25 (㊣ 0.86) mm to the left side while the largest vertical diameter was of 2.38 (㊣ 0.63) mm on the right and of 2.39 (㊣ 0.58) mm on the left side. It was predominantly found in the oval form, on the right side, of which 98.3% presented as a larger diameter the horizontal (type I). On the left side, all the oval foramens were classified as of type I. 76 (95%) appeared single on both sides. As to the localization related to the mandibular dentition, it was localized in similar statistic proportions between the 1st and 2nd premolars and above the 2nd premolar, in 45.17% of the mandibles, on the right side. On the left side it was predominantly found between the 1st and 2nd premolars 48.48% of the mandibles. The study of the MF is of vital importance to the acupuncture practice, as well as to modern surgical procedures, like anesthesia, requiring a detailed and precise study of the morphology and morphometry of the area. El objetivo de este trabajo fue estudiar la morfolog赤a y morfometr赤a del foramen mentoniano (FM), as赤 como evaluar su configuraci車n morfol車gica; tomar las medidas de su localization usando como par芍metro la distancia del foramen hacia el borde inferior de la mand赤bula y el reborde alveolar. 80 mand赤bulas secas se analizaron mediante la prueba de Chi-cuadrado y prueba t, con un 5% de significancia. Su distancia media, en el lado derecho, hasta el borde inferior de la mand赤bula (BIM) fue de 12,96 (㊣ 1,57) mm y del reborde alveolar (RA) fue de 12,82 (㊣ 3,4) mm. En el lado izquierdo se encuentro una distancia del BIM de 12,96 (㊣ 1,32) mm y del RA de 12,82 (㊣ 3,22) mm. El mayor di芍metro horizontal encontrado fue de 3,32 (㊣ 0,91) mm a la derecha y 3,25 (㊣ 0,86) mm a la izquierda, mientras que el mayor di芍metro vertical fue de 2,38 (㊣ 0,63) mm a la derecha y de 2,39 (㊣ 0,58) mm en el lado izquierdo.
