# An Evaluation of the Ramus Mandibular Asymmetry on the Panoramic Radiography
## 4 Discussion
They did not record any differences for any of the asymmetry indices, and they found the value of the condylar asymmetry index in the group with Angle Class I malocclusion in a percentage of 7.57%. Unlike the aforementioned study, we found notable differences between the two genders, and for the condylar asymmetry index, we found values of 15.3% in Angle Class I malocclusion in males and 10.5% in females [35]. [PERSON] et al. evaluated mandibular asymmetry in adolescent patients with unilateral posterior crossbite (UPC) and patients with normal occlusion (control group). Regarding the condylar asymmetry index (CAI), they found a significantly higher value in patients with unilateral posterior crossbite compared to the control group. Our study was carried out using children and included malocclusions in the transverse plane and malocclusions in the sagittal plane. Similar to the cited study, the condylar asymmetry index was determined with a high value in unilateral posterior crossbite but with a value different from the cited study; it had the highest value in Angle Class I malocclusions, and for the group of females, increased values of CAI were also recorded in Angle Class II/I, with condylar asymmetry in UPC having only the third place in terms of frequency in the group of females and the second position in the group of males [38]. Similar to [PERSON]'s study, [PERSON] et al. observed a condylar asymmetry index (CAI) in children with a high value in unilateral reverse occlusion, but these studies only investigated unilateral posterior crossbite compared to the control group with normal occlusion [49]. The novelty of our study comes from the fact that classification was made by classes of malocclusions, including in the study, in addition to UPC, the malocclusions from Angle's classification: Class I, Class II/1, Class II/2 and Class III. It is surprising that we would have expected the greatest asymmetry of the condyle to appear in the UPC (in our study, 11.8% males and 8.7% females), and despite this, we found higher values of asymmetry in Angle Class I malocclusions in all groups (15.3% males and 10.5% females), and in Class II/1 in the group of females (10.7%). [PERSON] et al. evaluated the association between different types of occlusions and mandibular asymmetry in young patients between 11 and 15 years. They calculated the asymmetry indexes using panoramic radiography in four groups of patients with Angle Class I, II/1, II/2, and III malocclusions and a control group (with neutral occlusion), and they did not notice any statistically significant differences between male and female patients [48]. The results of the research confirm [PERSON]'s study regarding the aforementioned classes of malocclusions, but an additional new type of occlusions was introduced, unilateral posterior crossbite, a type within which statistically significant differences were recorded at the level of the condylar index of asymmetry in the female and male study groups. In another study, [PERSON] et al. [37] investigated vertical asymmetries of the mandibular condyle in adolescent patients (11-16 years) with Angle Class I, Class II, Class III malocclusions, and unilateral posterior crossbite. They observed in all occlusions groups values of condylar asymmetry index higher than 3%, with patients with a unilateral posterior crossbite being the most asymmetric. Regarding gender, the authors observed statistically significant differences in the group with a unilateral posterior crossbite. They observed no statistically significant differences in the condylar asymmetry index between males and females in Angle Class I, II and III malocclusions. In the present study, although the age mean was different, similar results were observed as to those produced by [PERSON] et al., with the condylar asymmetry index recording values of over 3%, and in unilateral posterior crossbite, statistically significant differences were observed between the group of females and males.
