Slide2Common Indications for Dental Radiographs
(Laminate and post this next to dental x-ray machine)Fractured Teeth
Discolored Teeth
Missing Teeth
Resorptive Lesions (cats)Periodontal DiseasePockets over 3mm in dogsPockets over 2mm in catsOral Swelling/MassesDraining tracts on the gums, maxilla, or mandibleEnamel hypoplasia or deformed tooth
Gingival recession or hyperplasiaNasal DischargeEpistaxisPre- Post ExtractionClient educationNon-dental uses:Small patient extremitiesBirdsExotics/pocket petsNasal RadiographsPhalanges
Slide3Patient positioning- when learning
Sternal recumbency for the all maxillary viewsDorsal recumbency for the rostral mandibular views Lateral recumbency for parallel mandibular views
Slide4Parallel technique
*image of the caudal mandibular premolars and molars*
Slide5Parallel technique
*Cone head is placed parallel to plate or sensor*
Slide6Parallel view of a canine mandible
*Image of mandibular premolars and molars*
Slide7The Bisecting Angle (BA) Technique
A bisecting angle is the imaginary plane that equally divides the distance between the planes of the long axis of the plate/sensor and central axis of the tooth. Another way to attain proper alignment is to visualize the plane of the cone and align it parallel to the bisecting angle.
Plate/sensor
Bisecting angle (BA)
ToothTube head
Slide8Center on the desired teeth
*stand behind the cone first then move to the side of the patient to visualize the BA*
Slide9Bisecting angle of maxillary incisors
*Line x-ray tube up parallel to the bisecting angle*
BA
Slide10Maxillary incisors
Slide11Bisecting angle in the Cat
*Image of the rostral maxillary incisors*
BA
Slide12Feline Maxillary Incisors
Slide13Oblique maxillary canine
*BA positioning on the incisors first then move the cone slightly oblique to image the left canine*
Slide14Side view of oblique technique for the right maxillary canine
Slide15Right maxillary canine-oblique
Slide16Bisecting angle of maxillary premolar
*x-ray tube head is positioned between the first molar and the fourth premolar*
Slide17BA technique of the maxillary premolars and molars
*Come around and face the patient to adjust the cone to the BA*
BA
Slide18Right Maxillary PM2-4,M1
Slide19Tube shift technique to separate mesial roots of PM4
*BA first then tube shift cranial to caudal*
Slide20Tube shift technique to separate mesial roots of PM4
*BA first then tube shift caudal to cranial*
Slide21Right Maxillary PM4 with Root Separation
Slide22Acute Angle technique (feline)
(Slight elongation to avoid superimposition of the zygomatic arch)
Slide23Acute Angle=Elongated roots

Slide28Bisecting angle of first and second premolars in the mandible
*Use this technique to image PM1,2,3*
