Summary
Radiographic interpretation of canine maxillary teeth is challenging due to superimposed oral and nasal structures. This study identifies these interfering anatomical features in mesaticephalic dogs for improved veterinary dental diagnostics.
Area of Science:
- Veterinary Radiology
- Comparative Dental Anatomy
Background:
- Radiology is crucial for evaluating tooth roots and adjacent structures.
- Superimposition of oral and nasal anatomy complicates radiographic interpretation.
Purpose of the Study:
- To identify and locate anatomical structures superimposed on the maxillary canine tooth roots in canine radiographs.
- To aid in accurate interpretation of veterinary dental radiographs.
Main Methods:
- Radiographic analysis of mesaticephalic dog skulls.
- Identification and mapping of superimposed anatomical structures.
Main Results:
- Nasal conchae cause minimal interference.
- Vomer bone and maxillary structures (conchal crest, maxillary body-palatine process conjunction, palatine sulcus) create linear radiopacities.
- Incisivomaxillary canal and palatine fissure appear as radiolucent images.
- Sutures (incisivomaxillary, nasoincisive) vary in appearance with age.
Conclusions:
- Achieving diagnostic radiographic views requires balancing superimposition and image distortion.
- Close anatomical positioning of structures like the conchal crest and incisivomaxillary canal limits radiographic manipulation.
