Effects of hyperlipidemia on trabecular and cortical structures of the mandible. | LitMetric

AI Article Synopsis

  • The study aimed to analyze the mandibular bone structure in patients with hyperlipidemia using fractal dimension (FD) analysis and various radiomorphometric indices, comparing them to a healthy control group.
  • A total of 60 panoramic radiographs were examined, with 30 from hyperlipidemic patients and 30 from healthy individuals, focusing on specific measurements like mandibular cortical thickness, panoramic mandibular index (PMI), and mandibular cortical index (MCI).
  • Results indicated that hyperlipidemic patients had lower FD values, particularly in the angle of the mandible, while MCI also showed significant differences; however, there were no notable differences in cortical thickness or PMI between the two groups.

Article Abstract

Objectives: To evaluate the mandibular bone structure of patients with hyperlipidemia by fractal dimension (FD) analysis and panoramic radiomorphometric indices including mandibular cortical thickness measurement, panoramic mandibular index (PMI), mandibular cortical index (MCI) and to compare with the healthy group.

Methods: In total, 60 panoramic radiographs were included, including panoramic radiographs of 30 individuals with hyperlipidemia and 30 individuals with systemically healthy. FD analysis in the mandibular condyle, angle of the mandible, the distal side of the second premolar and anterior to mental foramen, PMI, MCI, and mandibular cortical thickness measurements were evaluated on radiographs. Independent samples -test was used for differences between healthy and hyperlipidemia groups with regard to age and PMI. Repeated measurement of variance with one within and one between factors in the comparison of four regions and two groups in terms of FD and cortical thickness measurements. Following this analysis, significant differences were detected by post-hoc Sidak test. Fisher-Freeman-Halton analysis was applied to determine the relationship between categorical variables.

Results: FD values of the hyperlipidemic patients were found to be lower than the healthy group. Between the hyperlipidemic and healthy groups, there was a difference in the angle of the mandible FD values ( = 0.020). There were no differences in the cortical thickness measurements and PMI between the groups ( > 0.05). There was a difference in MCI values between the groups ( < 0.05).

Conclusion: The trabecular structure of the angle of the mandible and the cortical bone structure of the mandible were found to be negatively affected by hyperlipidemia.
