Table 1 presents the demographic characteristics of the study population for both groups. As observed, there was no significant difference in the mean age between groups (\(p\) > 0.05), but there was an unbalanced gender distribution in the study group. \begin{table}

Table 1: Demographic characteristics of the study population (mean \(\pm\) SD = standard deviation). The OPT investigation showed that in the control group, the maximum bone loss reached 13.2 mm, with an average of 4.930 \(\pm\) 3.258 mm, while in the study group, the maximum horizontal bone loss was 11.3 mm, with an average of 5.191 \(\pm\) 2.109 mm. The CBCT 3D investigation displayed increased values for horizontal bone loss, both in the control and in the study group; in controls, the maximum horizontal bone loss reached 14.10 mm, with an average of 5.736 \(\pm\) 3.471, and in the study group, the maximum value was 12.40 mm, and the average was again slightly higher (6.152 \(\pm\) 2.519) (Table 2) (Figures 1-3). \begin{table}

Table 2: Horizontal bone loss: comparative descriptive statistics in the control/ENT cancer group. Figure 1: Orthopantomography of patient A.D., larynx cancer, 62 years old, assessment of horizontal bone loss (maximum 5.1 mm at tooth 46) and measurement of the size of periapical lesions present at tooth 23 is 3.6 mm. When evaluating the OPT, the dimensions of the periapical lesions found in the control group varied between 0 and 5.00 mm vs. 0 and 6.00 mm in ENT cancer patients. The evaluation of CBCT 3D highlights the same phenomenon, but the magnitude of the periapical lesions found was higher, both in the control group and in the study group, namely, 7.60 mm for the group control and 10.81 mm for ENT cancer. Figure 3: OPT–CBCT of Patient A.D., assessment of horizontal bone loss (maximum 6.8 mm at tooth 46) and measurement of the size of periapical lesions present at 23 is 4.5 mm.
