Dental pathologies are highly prevalent in pet rabbit populations, making oral radiography an essential tool in the evaluation of lagomorph dentitions. The unique anatomy of the rabbit's mouth limits the examination of the conscious animal to the rostral portion of it's mouth. In addition, the oral examination of an aradicular hypsodont tooth is restricted to the short coronal fraction of its crown. Erstwhile images obtained by the extraoral technique were once considered the most practical and informative tool in rabbit dentistry; however, limited visualization of the key structures of individual teeth became the major drawback of this technique. As new imaging technologies are becoming widely available and affordable for veterinarians, intraoral radiography offers the ability to prevent, diagnose, and treat oral pathologies in lagomorphs. This article describes a step-by-step procedure to obtain a full-mouth radiographic survey in rabbits. For this technique, a standard dental X-ray generator and intraoral storage phosphor plates are used while applying the bisecting angle technique. Among the advantages of this technique are detailed visualization of internal and external dental structures, identification of early lesions, and detection of occult pathologies. Furthermore, intraoral images offer superior resolution and higher diagnostic quality with minimal radiation exposure, making this method safer for the veterinarian, staff members, and their patients.
牙科疾病在宠物兔群体中非常普遍,这使得口腔放射成像成为评估兔科动物牙列的一项重要工具。兔子口腔独特的解剖结构使得对清醒动物的检查仅限于其口腔的前部。此外,对无根高冠齿的口腔检查仅限于其牙冠的短冠部。以前通过口外技术获得的图像曾被认为是兔牙科中最实用、信息最丰富的工具;然而,对单个牙齿关键结构的可视化有限成为了该技术的主要缺点。随着新的成像技术对兽医来说变得广泛可用且价格可承受,口腔内放射成像能够预防、诊断和治疗兔科动物的口腔疾病。本文描述了在兔子身上进行全口放射影像检查的分步程序。对于这项技术,在应用平分角技术时,使用标准的牙科X射线发生器和口腔内存储磷光板。该技术的优点包括能详细显示牙齿的内部和外部结构、识别早期病变以及检测隐匿性疾病。此外,口腔内图像具有更高的分辨率和更高的诊断质量,同时辐射暴露最小,这使得该方法对兽医、工作人员及其患者来说更安全。
