Section 1

Question Answer
occlusal techniqueused to examine large areas of the upper and lower jaw
occlusal surfaces chewing surfaces of posterior teeth
occlusal examinationa type of intraoral radiographic examination to inspect large areas of the maxilla or the mandible on one image
occlusal technique definitionmethod used to expose a receptor in occlusal examination
occlusal receptorsize 4 in adult size 2 in children
localization techniqueA method used to locate the position of a tooth or object in the jaws, bc the image does not depict the depth or is it is buccal or lingual
buccal object ruleUses 2 images to determine location of object
SLOB ruleS=same L= Lingual O= Opposite B= Buccal
right angle techniqueAcquire one image using periapical technique Acquire 2nd image using occlusal technique

Section 2

Question Answer
Purpose and use of occlusalA supplementary technique Used when need to see large area of maxilla or mandible
conditions occlusal images are used to locatefracture, salivary stones, lesions, maxillary sinus, cleft palate, changes in the size and shape or the maxilla, locate retained root tips or other foreign bodies
Principle of occlusal techniqueWhite side faces arch Placed between maxilla and mandible Patient bites on film/recepto

Question Answer
SLOB ruleAcquire one image using proper technique Acquire 2nd image shifting the beam mesially or distally from the object, Object moves SAME direction? It is lingual, Object moves OPPOSITE direction?, it is buccal
