what are the indications of equine dental radiographs
- trauma
- investigation of periodontal disease, endodontal disease and cysts/neoplasms
- assessment of teeth roots
discuss radiation saftey in the context of equine dental radiographs
- barrier protections (lead gown, gloves and thyroid gaurd)
- plate holder/stand
- xray machine stand
- exposure monitoring badge
- appropriate positioning and collimation
- minimal number of views
equine dentistry radiograph restraint methods
- sedation
- blinkers and ear plugs
- appropraite handler
- head stand
- incisor plate/gag
list common views used for equine dental radiographs
- laterolateral
- lateral obliques
- dorsoventral 30 degree lateral oblique
- ventrodorsal 45 degree lateral oblique
- dorsoventral
- open mouth obliqueintraoral
what is the center point for lateral oblique equine dental rads
rostral aspect of facial crest
discuss positioning of latero-lateral equine dental rads
- head normal position (for sinus fluid lines)
- centre on rostral aspect of facial crest
- good for premolars and molars as well as paranasal sinuses
how would you position the xray machine to take a 30 degree lateral oblique xray
what do you see
- maxillary apices on side adjacent to cassette
where would you position the cassette for a ventrodorsal 45 degree lateral oblique?
what would you see
mandibular apices on side adjacent to the cassette
discuss positioning of dorsoventral equine dental rads. what is seen
- mandible on cassette
- beam directed vertically
- centre: sagittal plane at the level of the medial ocular canthi
- mandible can be diverted laterally to show ventral conchal sinus radio-opacities, fracture planes and periodontal changes
discuss positioning of open mouth oblique equine dental rads
discuss positioning for intraoral equine dental rads
