This study aimed to assess the correlation of body mass index (BMI) and alveolar bone dimensions in the maxilla using cone-beam computed tomography (CBCT).
This retrospective, cross-sectional study evaluated 40 patients presenting to the Radiology Department of School of Dentistry, Islamic Azad University of Tehran during 2017-2019 who required CBCT scans of the maxilla for purposes not related to this study. The patients were divided into two groups (n = 20) with BMI ≥ 25 and 18 < BMI < 25. The maxillary alveolar bone height, and the buccal and palatal cortical bone thickness at 4 and 7 mm from the alveolar crest were measured on CBCT scans and compared between the two groups using pairwise correlation coefficient and independent t-test. Datawere analyzed using pairwise correlation coefficient and independent t-test via SPSS version 20.
The two groups were not significantly different regarding age or gender (P > 0.05). The buccal and palatal cortical bone thickness across all measured sites was significantly greater in patients with higher BMI. BMI had no significant correlation with alveolar bone height (P > 0.05). BMI had a positive correlation with buccal and palatal cortical bone thickness at the site of all teeth except for the palatal bone thickness at the site of first molar at 7 mm distance from the crest.
Patients with higher BMI showed higher buccal and palatal cortical bone thickness in the maxilla (except for one area) than patients with normal BMI. The buccal and palatal cortical bone thickness at the interdental areas was greater in patients with higher BMI. However, the alveolar bone height was not significantly different between the two groups.
本研究旨在使用锥形束计算机断层扫描（CBCT）评估体重指数（BMI）与上颌骨牙槽骨尺寸之间的相关性。
这项回顾性横断面研究评估了2017年至2019年期间前往德黑兰伊斯兰阿扎德大学牙科学院放射科就诊的40例患者，这些患者因与本研究无关的目的需要进行上颌骨CBCT扫描。患者被分为两组（n = 20），BMI≥25和18＜BMI＜25。在CBCT扫描上测量上颌牙槽骨高度，以及距牙槽嵴4和7毫米处的颊侧和腭侧皮质骨厚度，并使用成对相关系数和独立t检验在两组之间进行比较。通过SPSS 20版使用成对相关系数和独立t检验对数据进行分析。
两组在年龄或性别方面无显著差异（P＞0.05）。BMI较高的患者在所有测量部位的颊侧和腭侧皮质骨厚度明显更大。BMI与牙槽骨高度无显著相关性（P＞0.05）。BMI与除距牙槽嵴7毫米处第一磨牙腭侧骨厚度外的所有牙齿部位的颊侧和腭侧皮质骨厚度呈正相关。
BMI较高的患者上颌骨（除一个区域外）的颊侧和腭侧皮质骨厚度高于BMI正常的患者。BMI较高的患者牙间区域的颊侧和腭侧皮质骨厚度更大。然而，两组之间的牙槽骨高度无显著差异。
