摘要

背景与目的下颌下牙槽管（IAC）路径和颏孔（MF）位置的变化可能影响神经血管束的放置，这是下颌手术中一个重要的考虑因素。本研究旨在调查南非人群在全景x线片上IAC的形态学和形态测量学以及MF的位置。方法对200张数字全景x线片进行回顾性横断面研究。获得并分析了IAC的前后走向、垂直和水平位置以及形态计量学参数。对颏孔位置进行分类分析。结果在IAC的正反道（APC）中最常见的是椭圆型弧形管（55.00%）。中间位是IAC最常见的垂直位（48.30%）。IAC最常见的水平相关性为1型（45.50%），左右两侧下颌骨间差异有统计学意义。大部分MF位于4位（50.00%），15-19岁和40-50岁之间差异有统计学意义。IAC的平均测量值从第一磨牙下降到第三磨牙，在性别和年龄组之间有统计学上的显著差异。IAC的平均直径约为3-4 mm，相对恒定。结论与其他人群一样，大多数南非黑人具有良好的IAC康复APC。从垂直位置看，大部分根管（51.7%）位于高危区（高、低根管），女性根管发生率较高。临床医生应该期望发现MF与第二前磨牙的根尖对称：然而，随着年龄的增长，MF的位置会向后移动。

Morphological and morphometric analysis of the inferior alveolar canal and mental foramen in black South Africans: A panoramic radiographic study

Background and objectives

Variations in the route followed by the inferior alveolar canal (IAC) and the position of the mental foramen (MF) could impact the placement of the neurovascular bundle, a vital consideration during mandibular surgeries. This study was conducted to investigate the morphology and the morphometry of the IAC and the position of the MF as seen on panoramic radiographs in a South African population.

Methods

A retrospective cross-sectional study was conducted on 200 digital panoramic radiographs. The morphology, i.e., the anteroposterior course, the vertical and horizontal position, and the morphometric parameters of the IAC were obtained and analyzed. The mental foramen position was categorized and analyzed.

Results

Elliptic arc canals were the most frequently observed (55.00 %) anteroposterior course (APC) of the IAC. The intermediate position was the most common vertical position (48.30 %) of the IAC. The commonest horizontal relation of the IAC was type 1 (45.50 %), with a statistically significant difference between the right and left sides of the mandible. Many of the MF (50.00 %) were located at Position 4, with a statistically significant difference between the ages of 15–19 and 40–50. The mean measurement of the IAC decreased from the first molar to the third molar, with statistically significant differences between sexes and across age groups. The average diameter of the IAC was about 3–4 mm and was relatively constant.

Conclusion

As seen in other populations, most Black South Africans had a favorable APC of the IAC for rehabilitative purposes. Considering the vertical position, most of the canals (51.7 %) were in the high-risk zone (high and low canals), and females had a higher frequency of high canals. Clinicians should expect to find the MF symmetrically in line with the root tip of the second premolars: however, the position of the MF moves posteriorly with advancing age.

期刊介绍： Translational Research in Anatomy is an international peer-reviewed and open access journal that publishes high-quality original papers. Focusing on translational research, the journal aims to disseminate the knowledge that is gained in the basic science of anatomy and to apply it to the diagnosis and treatment of human pathology in order to improve individual patient well-being. Topics published in Translational Research in Anatomy include anatomy in all of its aspects, especially those that have application to other scientific disciplines including the health sciences: • gross anatomy • neuroanatomy • histology • immunohistochemistry • comparative anatomy • embryology • molecular biology • microscopic anatomy • forensics • imaging/radiology • medical education Priority will be given to studies that clearly articulate their relevance to the broader aspects of anatomy and how they can impact patient care.Strengthening the ties between morphological research and medicine will foster collaboration between anatomists and physicians. Therefore, Translational Research in Anatomy will serve as a platform for communication and understanding between the disciplines of anatomy and medicine and will aid in the dissemination of anatomical research. The journal accepts the following article types: 1. Review articles 2. Original research papers 3. New state-of-the-art methods of research in the field of anatomy including imaging, dissection methods, medical devices and quantitation 4. Education papers (teaching technologies/methods in medical education in anatomy) 5. Commentaries 6. Letters to the Editor 7. Selected conference papers 8. Case Reports
