Abstract

Objectives: Main objective of this study was to estimate gender and age changes in the position of MF in relation to the occlusal plane among boys and girls aged 7 to 11 years old, also to record the distance between MF with each of the anterior border of ramus (AB), posterior border of ramus (PB), and the inferior border of ramus (IB) near the mandibular angle. Another aim was to find a correlation between the gonial angle (GA) and other mandibular ramus parameters.

Materials and Methods: 200 normal panoramic radiographs belong to 100 boys and 100 girls between 7-11 years old age, were included in this study. Radiographs collected from different sources. Seven points; four planes; four lines; and one angle were traced on the right side of the radiographs. AutoCAD and Photoshop programs were used to measure distances from MF to each of the occlusal planes; AB; PB, and IB. also GA were measured. These measuring were assessed and compared in different age and sex groups to determine the relative position of MF to the occlusal plane and other parameters.

Results: These results showed statistically significant increasing in all parameters in relation to the aging process and both sexes (P value<0.5). Boys had higher measurements than girls in all parameters except for the distance between MF and occlusal plane. GA showed a negative correlation with aging in both sexes.

Conclusions: It is concluded that IANB anesthesia is well done if the dental needle inserted below and above the occlusal plane in 7-9 and 10-11 years old boys respectively. While it should be inserted below and above the occlusal plane in 7-8 and 9-11 years old girls respectively. GA has a negative correlation with the occlusal plane and other mandibular parameters (P value<0.5). The relation between MF distance to other mandibular parameters and with advancing age in both sexes were statistically significant (P value<0.5).

Keywords: mandibular foramen, panoramic radiograph, occlusal plane.
