The aim of this research was to determine the relationship between mandibular cortical bone density and the risk of osteoporosis evaluated using Cone Beam Computed Tomography in Lima, 2021. The study was conducted using a deductive method with a quantitative approach, basic type, and a descriptive correlational design, retrospective, observational, and cross-sectional. The study sample consisted of 100 tomography scans from patients aged 40 to 65 years. The technique used was observation, and the data obtained were recorded in the data collection sheet. Additionally, inferential and descriptive statistics were applied to obtain the results. The average age of the population evaluated using the mentonian and Klemetti indices was 55 years, with the average mentonian index measuring 3.8 mm, showing a decrease in cortical thickness and porosity from the age of 50. According to the Klemetti index, 43% of participants showed a high risk of developing osteoporosis, with a porous and permeable mandibular cortex. The mentonian index revealed that 25% had a thin mandibular cortex, indicating a high risk of osteoporosis. According to the correlation between both indices, C1 (normal) was associated with a mentonian index average of 4.2 mm; classification C2 (osteopenia) with an average of 3.8 mm, and classification C3 with an average of 2.7 mm. Moreover, the risk of osteoporosis was found to be 65% in females and 35% in males. The study concluded that there is a high and significant correlation (R = 0.891, p = 0.000) between mandibular cortical bone density and the risk of osteoporosis.
