Fig. 5From: Frequency and anatomic variability of the mandibular lingual foramina: a cone-beam CT studyAxial multiplanar reconstruction to estimate the area of the floor of mouth considering it as a triangle. The distance between the mental foramina (base of the triangle) was 4.680 cm and the perpendicular line reaching the symphysis (height of the triangle) was 0.462 cm. The estimated area of the floor of mouth was then calculated obtaining 25.69 cm2Back to article page
