Sažetak
Radiographic assessment of “bone quantity“ is of great value in planning dental treatment and it also has its applications in orthodontics.
The aim of this study was to assess the cortical thickness of the lower border of the mandible using linear radiomorphometric indices, and to determine if it is correlated with different age, gender and malocclusion categories in orthodontic pretreatment period of the patients.
Seventy seven patients - 30 boys (42.8%) and 47 girls (57.2%), participated in the study.
The results of the statistical analysis revealed no signifi cant difference between the right and the left side measurements for mental and antegonial indices (p>0.05). The right gonial index was signifi cantly higher than the left (p<0.05). All linear radiomorphometric indices increased with age. The cortical thickness at the angle of the mandible demonstrated the highest value in Class III malocclusion group (p<0.01). Based on the results of this study, assessment of linear radiomorphometric indices could be clinically valuable for the evaluation of the growth and development of the mandible and for assessing results of orthodontic treatment.
