In equine veterinary practice, the integration of radiology imaging and thorough physical examinations is crucial for accurate diagnoses and effective treatment plans. This article discusses a case study of a horse referred for evaluation of a dental issue, highlighting the importance of these diagnostic tools.
The Case: Evaluating a Dental Issue
A horse was referred for an evaluation of tooth number 109, which appeared suspicious during an oral exam. The examination revealed some open pulps, prompting the need for further investigation. The veterinarian utilized an endoscope to visualize the mouth, noting the conditions of surrounding teeth:
Teeth 106, 107, and 108: Normal appearance.
Tooth 109: Complicated fracture with visible granulation tissue and open pulps.
Teeth 1 and 2: Appeared normal, while the buccal and lingual aspects of all teeth were thoroughly inspected.
This initial visual assessment highlighted the significance of performing comprehensive oral exams, as conditions may vary across different teeth.
Importance of Radiographs
Following the oral examination, a lateral oblique dorsal-to-ventral radiograph was taken, which initially appeared normal. However, the veterinarian emphasized the necessity of performing a palatal view radiograph for a more complete diagnosis.
While the lateral oblique view showed a healthy lamina dura around tooth 109, it failed to reveal critical issues with the palatal root. The palatal view is essential because it can expose hidden pathologies, such as lysis or cementoma, especially since the palatal root often communicates with adjacent pulps that were already compromised.
How to Perform a Palatal View
To obtain the palatal view, the veterinarian positioned the horse’s mouth open using a dental block, allowing for a ventral-to-dorsal radiographic angle. This technique effectively elevated the palatal root while allowing the two buccal roots to drop, providing a clearer view of potential abnormalities.
This step was crucial; the resultant images confirmed the presence of a peripheral abscess, leading to the recommendation for extraction of the affected tooth. Had the radiographs shown normal results, a more conservative treatment plan might have been viable.
Efficient Diagnostic Process
The entire diagnostic process was completed efficiently in about 20 minutes, demonstrating the effectiveness of integrating radiology and physical exams. The veterinarian already had a maxillary nerve block in place while documenting the procedure, highlighting the speed and efficiency achievable when employing modern techniques.
Rethinking Anesthesia in Equine Dentistry
An important takeaway from this case is the push against outdated practices, particularly the use of general anesthesia for dental extractions in horses. The veterinarian shared concerns over a recent report recommending general anesthesia for a tooth extraction, which would incur significant costs and risks.
Today, advancements in veterinary dentistry allow for many procedures, including molar extractions that involve the sinuses, to be performed while the horse is standing. This not only minimizes risk but also reduces recovery time and overall expenses for horse owners.
Conclusion
The integration of radiology imaging with physical examinations in equine dentistry enhances diagnostic accuracy and treatment effectiveness. This case underscores the importance of comprehensive oral exams and the utility of advanced imaging techniques in identifying dental issues. As veterinary practices evolve, embracing standing procedures over outdated methods can lead to better outcomes for equine patients, ensuring they receive the best care possible.
