摘要
马的牙齿错牙合很常见。本研究的目的是报告成年埃及-阿拉伯（SEAR）和纯种（TB）马颅骨计算机断层扫描（CT）的正常头影测量值，并比较两个品种之间的测量差异。对29匹临床正常成年马（15匹SEAR；14匹TB）进行了直立颅骨CT检查，并进行了头影测量。所有9个头影测量值以及窦间角在TB中均显著高于SEAR（P P = 0.002），而对于上颌颊齿长度：筛骨线比率（Mxa/EtL），SEAR的值明显大于TB（P = 0.0007）。SEAR头影测量值以及某些比率与TB有显著差异，并可能对该品种错牙合的发展产生影响。需要进一步的研究来确定这两个品种之间的这些头影测量差异是否会使SEAR易患错牙合畸形。
Comparison of Computed Tomography Assisted 3D Cephalometric Measurements in Straight Egyptian Arabian and Thoroughbred Horses.
Dental malocclusions are commonly encountered in horses. The objective of this study was to report the normal cephalometric values from skull computed tomography (CT) scans of adult Straight Egyptian Arabian (SEAR) and thoroughbred (TB) horses and to compare differences in the measurements between the two breeds. Standing skull CTs were performed on 29 clinically normal adult horses (15 SEAR; 14 TB) and cephalometric measurements were taken. All 9 cephalometric measurements, as well as the interincisal angle, were found to be significantly greater in TB than SEAR (P < 0.05). TB were found to have significantly greater facial line: mandibular length (FL/ML) ratios compared to SEAR (P = 0.002) whereas for the maxillary cheek teeth length: ethmoidal line ratio (Mxa/EtL), SEAR were found to have significantly greater values than TB (P = 0.0007). SEAR cephalometric measurements, as well as certain ratios, differ significantly from TB and could have an impact on the development of dental malocclusions in this breed. Further investigation is needed to ascertain whether these cephalometric differences between the two breeds predispose the SEAR to the development of dental malocclusions.
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.
