The Cone Beam Computed Tomography (CBCT) is currently being used as the most common diagnostic method to evaluate the bone density of the maxilla and the mandible for planning dental implant. Aim: The aim of the study is to check the quantitative alveolar bone density in complete or partial edentulous and dentulous male and female patients among Riyadh sample population in Saudi Arabia.
The study involved a cross-sectional analysis of 231 consecutive CBCT images of 231 different patients (115 males and 116 females). The scans were of Saudi National patients who were partially or completely edentulous without any bone infections in the maxilla and the mandible. The findings are presented as descriptive statistics and inferential statistics: student -t-test for two group means, ANOVA for three groups, Post-hoc LSD test for multiple comparisons, Levene statistics for testing the homogeneity of variances and a statistical significance at 5% level.
Comparison of mean alveolar bone density in maxillae of dentulous male smokers showed a statistically significant difference for bucco-cortical plate and cancellous bone among different regions. In dentulous male nonsmokers, no significant difference was observed for maxillary regions, while in mandibular areas, a statistically significant difference was seen for buccal cortex, palatal cortex, and cancellous bone among different regions. While studying the scans of female dentulous patients, a statistically significant difference was observed in alveolar bone density for all the areas.
Evaluation of bone density is an important step in treatment planning and this study was aimed to provide insight into bone density patterns of population in Riyadh, Saudi Arabia. Further similar studies in different populations can help in planning for more efficient treatment outcomes.
锥形束计算机断层扫描(CBCT)目前是评估上颌骨和下颌骨骨密度以规划牙种植体时最常用的诊断方法。目的:本研究的目的是检查沙特阿拉伯利雅得样本人群中全口或部分无牙及有牙的男性和女性患者的牙槽骨定量密度。
本研究对231例不同患者(115例男性和116例女性)的231张连续CBCT图像进行了横断面分析。扫描对象为沙特本国患者,他们部分或完全无牙,上颌骨和下颌骨无任何骨感染。研究结果以描述性统计和推断性统计呈现:两组均值采用学生t检验,三组采用方差分析,多重比较采用事后LSD检验,采用Levene统计检验方差齐性,显著性水平为5%。
有牙男性吸烟者上颌骨平均牙槽骨密度比较显示,不同区域的颊皮质板和松质骨存在统计学显著差异。在有牙男性不吸烟者中,上颌区域未观察到显著差异,而在下颌区域,不同区域的颊皮质、腭皮质和松质骨存在统计学显著差异。在研究有牙女性患者的扫描图像时,所有区域的牙槽骨密度均观察到统计学显著差异。
骨密度评估是治疗计划中的重要一步,本研究旨在深入了解沙特阿拉伯利雅得人群的骨密度模式。在不同人群中进行进一步的类似研究有助于规划更有效的治疗结果。
