ABSTRACT
Knowledge of variations in MF location, size and shape is important when anesthetizing nerves of the mandibular region in dental procedures. The location, shape and position of the MF were determined in 119 human mandibles of unknown age and sex from different KP medical institutions. Parameters determined were MF length and width; accessory mental foramen (AMF) width; MF and AMF to midline (MF-ML) (AMF-ML), upper (MF-UM) (AMF-UM) and lower mandibular margins (MF-LM) (AMF-LM) and posterior border of the mandibular ramus (MF-PRM) (AMF-PRM). AMF position in relation to the MF was also noted. MF were mainly oval and situated below the second premolar. MF mean length and width were 2.4 ± 0.89 (right) and 2.4 ± 0.727 mm (left), and 3.0 ± 0.80 (right) and 2.9 ± 0.94 mm (left) respectively. MF-ML, MF-UM, MF-LM and MF-PRM distances on the right and left sides were 29.1 ± 2.19 mm and 28.1 ± 2.12 mm; 11.0 ± 3.99 mm and 11.2 ± 3.98 mm; 13.1 ± 1.83 mm and 12.8 ± 1.74 mm; and 69.3 ± 5.52 mm and 68.7 ± 5.02 mm, respectively. Double mental foramen (DMF) were observed on both sides (10.9 % right, 12.6 % left) with length and width 0.7 ± 0.42 mm and 0.9 ± 0.34 mm (right) and 0.8 ± 0.32 mm and 1.0 ± 0.47 mm (left) they were mainly oval (5.8 % right, 7.56 % left). DMF-MF distance was 8.9 ± 4.58 mm on the right and 6.6 ± 4.11 mm on the left. An oval accessory mental foramen was observed in one mandible. There was no difference between right and left MF; however differences in the parameters measured were observed in relation to other populations indicating the need to be aware of such differences when undertaking surgical procedures around the MF.
RESUMEN
El conocimiento de las variaciones del foramen mental (FM), su ubicación, tamaño y forma es importante al momento de anestesiar los nervios de la región mandibular en procedimientos dentales. La ubicación, forma y posición del FM se determinó en 119 mandíbulas humanas, de edad y sexo desconocidos, de diferentes instituciones médicas de Pakistan. Los parámetros determinados fueron longitud y ancho; ancho del foramen mental accesorio (FMA); MF y AMF a la línea mediana (FM-LM) (FMA-LM), margen superior (FM-MS) (FMA-MU) y margen inferior (FM-MI) (FMA-MI) y el margen posterior de la rama mandibular (FM-RMP) (FMA-RMP). También se observó la posición del FMA en relación con el FM. La forma del FM fue principalmente ovalada y situado por debajo del segundo premolar. Los datos de longitud y anchura del FM fueron 2,4 ± 0,89 (derecha) y 2,4 ± 0,727 mm (izquierda), y 3,0 ± 0,80 (derecha) y 2,9 ± 0,94 mm (izquierda), respectivamente. Las distancias FM-LM, FM-MS, FM-MI y FM-MRP en el lado derecho e izquierdo fueron 29,1 ± 2,19 mm y 28,1 ± 2,12 mm; 11.0 ± 3.99 mm y 11,2 ± 3,98 mm; 13,1 ± 1,83 mm y 12,8 ± 1,74 mm; y 69,3 ± 5,52 mm y 68,7 ± 5,02 mm, respectivamente. Se observaron foramenes mentales dobles (FMD) en ambos lados (10,9 % derecho, 12,6 % a la izquierda) con una longitud y ancho de 0,7 ± 0,42 mm y 0,9 ± 0,34 mm (derecha) y 0,8 ± 0,32 mm y 1,0 ± 0,47 mm (izquierda) fueron principalmente ovalados (5,8 % derecha, izquierda 7,56 %). La distancia FMD-FM fue de 8,9 ± 4,58 mm a la derecha y 6,6 ± 4,11 mm en el izquierdo. Se observó un foramen mental accesorio ovalado en una mandíbula. Hubo diferencia entre FM derecho e izquierdo. Sin embargo, las diferencias en los parámetros medidos fueron observados en relación con otras poblaciones que indican la necesidad de ser conscientes de estas diferencias al realizar procedimientos quirúrgicos en todo el MF.
