Abstract
Objectives: The purpose of this study was to evaluate the usefulness of the limited cone-beam X-ray CT (3DX) (Morita Co., Japan) in measuring the thickness of the roof of the glenoid fossa (RGF) of the temporomandibular joint (TMJ). Material and methods: Twenty-one TMJs removed at autopsy from 21 cadavers were investigated macroscopically using dissection and 3DX imaging. A Digimatic Outside Micrometer and a 3DX-image tool were used to measure the minimum thickness of the RGF. Multiple measurements were made to identify the thinnest area. Once the thinnest areas had been identified, three linear measurements were made and the average value was used for statistical analysis. Results: The average macroscopic examination measurement was 1.37 mm (range 0.55–3.6 mm) and the average 3DX image measurement was 1.22 mm (range: 0.51–3.0 mm). There was no significant difference between these two groups using the Mann-Whitney U-test The Spearman's correlation coefficient by rank between these two groups was Conclusion: These results suggest that bone thickness measurements of the RGF by 3DX imaging was effective.Keywords
