The aim of the study is to evaluate the usefulness of cone-beam computed tomography (CBCT) in the assessment of the relationship between the cemento-enamel junction (CEJ) and bone crest of the anterior mandibular cortex. The study population comprised 39 males and 61 females, aged 18-71. A GENDEX GXCB-500 machine, i-CAT Vision and CorelDraw 9 software were used. The distances between the CEJ and bone crest at buccal and lingual sides of six anterior mandibular teeth were measured. Descriptive statistical methods, Student's -test and ANOVA were used. The mean distance between the bone crest and CEJ was 2.32 mm ± 0.78 mm at the buccal and 2.52 mm ± 0.85 mm at the lingual side. It was found that in males aged over 50 years, the mean distance at the buccal side was 2.84 mm ± 0.79 mm and was significantly higher than in males aged 49 and less - 2.08 mm ± 0.41 mm. The mean distance at the lingual side was 3.28 mm ± 1.08 mm and was significantly lower in the age group of 49 years and less - 2.10 mm ± 0.41 mm. CBCT allows determining the distance between the CEJ and crestal bone margin at buccal and lingual sides. The data provide crucial information for planning orthodontic treatment, implant placement and periodontal therapy.
本研究的目的是评估锥形束计算机断层扫描（CBCT）在评估下颌前部皮质牙骨质-釉质界（CEJ）与牙槽嵴之间关系中的作用。研究对象包括39名男性和61名女性，年龄在18至71岁之间。使用了GENDEX GXCB - 500机器、i - CAT Vision和CorelDraw 9软件。测量了下颌前部六颗牙齿颊侧和舌侧的CEJ与牙槽嵴之间的距离。采用描述性统计方法、学生t检验和方差分析。牙槽嵴与CEJ之间的平均距离在颊侧为2.32毫米±0.78毫米，在舌侧为2.52毫米±0.85毫米。研究发现，50岁以上男性的颊侧平均距离为2.84毫米±0.79毫米，显著高于49岁及以下男性的2.08毫米±0.41毫米。舌侧平均距离为3.28毫米±1.08毫米，在49岁及以下年龄组中显著更低，为2.10毫米±0.41毫米。CBCT可用于确定颊侧和舌侧CEJ与牙槽嵴边缘之间的距离。这些数据为正畸治疗、种植体植入和牙周治疗的规划提供了关键信息。
