Summary

This summary is machine-generated.

Cancer patients, including those with head and neck cancer, show significantly reduced mandibular bone density. Radiomorphometric indices like mental index (MI) and panoramic mandibular index (PMI) reveal these changes, impacting bone health.

Area of Science:

Dentistry
Oncology
Radiology

Background:

Antineoplastic therapies can affect bone metabolism.
Mandibular bone changes may occur following cancer treatment.

Purpose of the Study:

To compare mandibular cortex thickness and resorption in cancer patients versus controls.
To evaluate radiomorphometric indices after antineoplastic therapy.

Main Methods:

Retrospective analysis of 287 panoramic radiographs.
Assessment of mental index (MI), panoramic mandibular index (PMI), and mandibular cortical index (MCI).
Statistical analysis using ANOVA and Kruskal-Wallis tests.

Main Results:

Patients with head and neck cancer (AG) and other cancers (BG) exhibited significantly lower MI, PMI, and MCI compared to controls (CG).
Males predominated in AG, while females predominated in BG and CG.
Tongue carcinoma was prevalent in AG; breast carcinoma in BG.

Conclusions:

Radiomorphometric indices (MI, PMI, MCI) are significantly reduced in cancer patients.
These findings highlight potential mandibular bone alterations post-cancer treatment.
