Summary
This study establishes standardized dental radiography techniques for rhesus macaques, improving diagnostic accuracy for oral pathologies. These methods enhance surgical planning and welfare for research primates.
Area of Science:
- Veterinary Radiology
- Primate Dentistry
- Comparative Oral Pathology
Background:
- Dental radiology is crucial for oral health assessments and surgery in animals and humans.
- Standardized dental radiography techniques for rhesus macaques are currently underdeveloped.
- Developing these techniques is essential for research and clinical applications in nonhuman primates.
Purpose of the Study:
- To establish practical and reproducible methods for high-quality dental radiography in rhesus macaques using a handheld X-ray system.
- To document common dental pathologies in rhesus macaques via radiography.
- To provide a foundation for broader application of dental radiology in nonhuman primates.
Main Methods:
- Anatomic landmarks, X-ray beam, and sensor angles were determined using a preserved rhesus macaque skull.
- Techniques were applied to 12 anesthetized rhesus macaques for assessment and presurgical planning.
- Radiographs were obtained for all maxillary and mandibular teeth.
Main Results:
- High-quality dental radiographs were successfully acquired for all teeth in rhesus macaques.
- Common dental pathologies, including periodontal disease, root resorption, and tooth fractures, were documented.
- The established techniques proved effective for diagnostic assessment and presurgical planning.
Conclusions:
- This study provides detailed, reproducible techniques for rhesus macaque dental radiography.
- Dental radiography is a valuable diagnostic tool for identifying pathology and planning oromaxillofacial surgery in research primates.
- Implementing these techniques enhances diagnostic accuracy, improves surgical outcomes, and supports the welfare of rhesus macaques.

01:24X-ray Imaging
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
01:20Imaging Studies for Cardiovascular System III: X-Ray
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
