Assessment of nutrient canals in relation to jaw cysts, trabecular bone structure and dental regions: A CBCT study.

OBJECTIVE

To investigate the relationship of nutrient canals with jaw cysts, trabecular bone density, and dental regions using cone-beam computed tomography (CBCT).

DESIGN

This retrospective study analyzed 120 CBCT images from 60 patients with unilateral jaw cysts. Nutrient canals were identified and localized on both the cyst-affected side and contralateral, unaffected side of the jaw for each patient. Alveolar trabecular structure was assessed by comparing Hounsfield Unit (HU) values between affected and unaffected sides. Statistical analyses included paired t-tests, Fisher's exact test, and intra-observer reliability assessment.

RESULTS

Nutrient canals were significantly more prevalent in cyst-affected jaw regions. Their presence was associated with areas exhibiting pericystic trabecular sclerosis, as reflected by elevated HU values. While nutrient canals were commonly observed in the anterior regions of both healthy and affected jaws, their presence in premolar and molar regions was restricted to cyst-affected areas.

CONCLUSIONS

Nutrient canals, typically found in the anterior jaws, appear to develop in posterior regions in association with jaw cysts, particularly in the presence of trabecular sclerosis. Their identification on CBCT scans is important for treatment planning and for minimizing potential surgical complications.
