摘要

这项回顾性研究对 161 只狗的上颌前磨牙和臼齿进行了评估,并使用锥形束计算机断层扫描确定了牙根顶端骨覆盖不完全的牙根。牙根与鼻腔腹侧、上颌凹陷、眶下管和翼腭窝相关的背侧解剖部位。研究发现,上颌前磨牙和臼齿的所有牙根都有可能出现牙根尖骨覆盖不全的情况,其中有 26.7% 的牙根尖骨覆盖不全。研究未发现与性别有明显关系。发现与体重有明显关系,且随着体重的增加而降低。在单变量建模和多变量建模中,分别发现只有 35.7% 和 14.2% 的牙根的面部指数与头骨形状有显著关系。了解这些牙根的解剖结构对于采用安全有效的拔牙技术、减少先天性创伤以及了解牙周病和牙髓病对局部的潜在影响具有重要作用。

Assessment of Incomplete Apical Bone Coverage of Maxillary Premolar and Molar Roots Using Cone Beam Computed Tomography in 161 Dogs.

This retrospective study assessed maxillary premolar and molar teeth and identified roots with incomplete apical bone coverage using cone beam computed tomography in 161 dogs. The associated dorsal anatomic sites that the roots communicated with were the ventral nasal meatus, maxillary recess, infraorbital canal, and pterygopalatine fossa. The study found that all roots of the maxillary premolar and molar teeth have the potential for incomplete apical bone coverage, with 26.7% having incomplete apical bone coverage. No significant association with sex was found. A significant association with weight was found, and this lowered with increasing body weight. Facial index, as a determinate of skull shape, was found to be significant in only 35.7% of roots in univariate and 14.2% of roots in multivariate modeling. Knowledge of the anatomy of these roots plays an important role in safe and effective extraction techniques, in reducing iatrogenic trauma, and in understanding the potential local effects of periodontal and endodontic disease.

期刊介绍: The Journal of Veterinary Dentistry (JOVD) is the official peer-reviewed publication of the Foundation for Veterinary Dentistry. The JOVD provides a continuing education forum for veterinary dental scientists, veterinarians, dentists, and veterinary/dental technicians and hygienists who are engaged in veterinary dental practice. JOVD articles provide practical and scientifically sound information covering not only the medical and surgical aspects, but also specific categories as they relate to clinical practice.
