Sažetak
Purpose: The purpose of the study was to examine the radiomorphometric indices of the mandible on panoramic radiographs in adult population, to identify their normal ranges and to investigate their relationships with age, gender and the presence of antagonistic contacts in the distal segments of the mandible. Methods and Materials: A total of 300 patients (18 to 82 years old ; mean age 43 ; 129 men, 168 women) participated in the study. Three quantitative indices, cortical width at the gonion (GI), at the antegonion (AI) and below the mental foramen (MI), were measured bilaterally on panoramic radiographs by one trained observer. The variations in measured variables between age groups (six 10-year age groups), gender (men/women) and presence of antagonistic contacts in distal segments (yes/no) were analysed. Results: All radiomorphometric indices demonstrated statisticaly significant difference between different age groups (p<0.05). There was a general downward trend with age until the seventh decade, when radiomorphometric values began to fall sharply compared to the mean values for the population (p<0.05). Men demonstrated thicker mandibular inferior cortex than women (p<0.05). The patients with the antagonistic contacts of the opposing teeth in both distal segments demonstrated higher radiomorphometric values in comparison to the patients with no antagonistic contacts in the same area of the jaw (p<0.05). In stepwise linear regression analysis, the presence of antagonistic contacts in distal segments demonstrated a strongly significant relationship with all radiomorphometric indices (p<0.001).
