Computed tomography-based assessment of maxillary bone tissue in females

Abstract

BACKGROUND: Assessing X-ray features of the maxillofacial area in adults, including gender-related differences in bone tissue structure in males and females, is a crucial task in dentistry.

AIM: To assess the density and thickness of maxillary bone tissue in females.

MATERIALS AND METHODS: The assessment of maxillary bone tissue was based on computed tomography findings for 25 female patients (mean age 34.61 ± 6.08 years).

RESULTS: In females, the minimum cancellous bone thickness in the vestibular part is 0.23 ± 0.15 mm in Segment 1 and 0.25 ± 0.17 mm in Segment 2. The maximum cancellous bone thickness in the palatal part is 3.3 ± 1.5 mm in Segment 1 and 3.27 ± 1.47 mm in Segment 2. The minimum cancellous bone thickness in the palatal part is 1,250 ± 125 c.u. in Segment 1 and 1,250 ± 125 c.u. in Segment 2. The maximum compact plate density in the vestibular part is 2,023 ± 245 c.u. in Segment 1 and 2,024 ± 246 c.u. in Segment 2. The minimum bone tissue thickness in the maxilla was observed in the central incisor area in the vestibular part (0.25 ± 0.17 mm). The maximum compact plate density in the maxilla was observed in the premolar and molar area in the vestibular part (3.27 ± 1.47 mm). The minimum bone tissue density in the maxilla was observed in the central incisor and canine area in the vestibular part (1,250 ± 125 c.u.). The maximum bone tissue density in the maxilla was observed in the premolar and molar area in the vestibular part (2,120 ± 110 c.u.).

CONCLUSIONS: The density and thickness of compact plate and cancellous bone of the maxilla in the vestibular and palatal parts in females were determined. In case of distal and mesial occlusion, there were no significant differences in the density and thickness of bone tissue. The maximum cancellous bone thickness in the palatal part was observed from incisors to first premolars, with a significant decrease from second premolars to molars. Compact plate density in the vestibular part increased from canines to molars.
