Section 1

Question Answer
bitewing techniqueexamines interproximal surfaces
bitewing techniqueallows us to see alveolar crest and detect bone loss
interproximalthe space between adjacent teeth
interproximal examinationthe radiograph of the image that captures the interproximal spaces
bite-wing receptorthe film, the phosphor plate, or the digital sensor (different sizes)
alveolar bonebone between two adjacent teeth
crestal bonecoronal most portion of the alveolar bone in the alveolar crest portion
contact areas the medial or distal surfaces of two adjacent teeth
contacts, openyou can see each medial or distal contact of each tooth
contacts, overlappedwhen you have an error in bitewing and you cannot see the contacts
horizontal and vertical bitewingsthe placement of the receptor

Section 2

Question Answer
Principles of Bite-wing Technique 1.receptor is placed parallel to the crowns of maxillary and mandibular teeth
Principles of Bite-wing Technique 2. Patient bites on the bitewing tab or beam alignment device to stabilize receptor
Principles of Bite-wing Technique 3. Horizontal angulation

Section 3

Question Answer
bitewing alignment devicewe want the center to go through the contacts
bitewing tabtab in the middle of the film bite on this so that it is centered and you get equal portions of max and mand

Section 4

Question Answer
size 0 bitewing receptorFor posterior teeth of children with primary dentition
size 1 bitewing receptorFor the posterior teeth of children with mixed dentitions, and sometimes vertical bitewings
size 2 bitewing receptorFor posterior teeth of adults, placed horizontally or vertically, and sometimes for mixed dentition
size 3 bitewing receptorFor bite-wings, not recommended for adult patients

Section 5

Question Answer
correct horizontal angulationthe beam is going in between two teeth
incorrect horizontal angulation if too far mesial or distally, then doctor will not be able to see those contacts and will be overlapped

Section 6

Question Answer
correct vertical angulation use about +10 degrees
too much positive vertical angulation Too much of the maxillary roots and distortion of mandibular crowns
negative vertical angulation Too much mandibular apices and distortion of maxillary crowns

Section 7

Question Answer
receptor placement rule of bitewing make sure it is placed over the area you want to image premolar-line receptor up with distal half of canine
receptor position rule of bitewingparallel to the maxillary and mandibular crowns
vertical angulation rule of bitewing between 0-10ยบ in order to have the best angulation, you want them looking straight ahead and their occlusal plan parallel to the floor
horizontal angulation rule of bitewing direct the center beam in-between the contacts of two teeth
receptor exposure rule of bitewingmake sure that the center beam is centered on the receptor

Section 8

Question Answer
CMRS definitioncomplete mouth radiographic sequence, also called FMX
CMRSExpose all anterior periapical receptors first Follow with posterior periapical receptor Finish with bite-wing exposures
bitewing sequencepremolar, then molar

Section 9

Question Answer
premolar bitewing receptor placementline the anterior edge of the sensor with the distal half of the canine should have the distal of the canine, all premolars, and 1st molar
molar bitewing receptor placementhalf of premolar and all of your molars
vertical bitewings Used to examine the level of alveolar bone Receptor placed vertically
why take vertical bitewings?to see the bone loss on periodontal disease, sometimes loss so great, cannot see the bone level at all on a horizontal bitewing

Section 10

Question Answer
Edentulous Spaces bitewing modificationin order to place the receptor, you can fold up a two by two and put it in the space or a cotton roll
bony growth bitewing modificationAKA-tori palatal- push receptor on other side of the tori, more towards the opposite side, if too much you may have to take PA.s instead

Section 11

Question Answer
number or exposures for adult bitewingstypically 4, sometimes 2
number or exposures for children bitewingtypically 2, depending on age and if they have perm. molars
number of exposures for mixed dentitiontypically 4
number of exposures for vertical bitewingtypically 7- 3 anterior and 4 posterior
