24
Q

location of sensor for max molar

A

Toward the center of plate

25
Q

How to place a mandibular posterior sensor

A
  • Retrat check and place front edge of sensor into mouth between tongue and teeth at a downward angle of 45 degrees for comfort
  • slide sensor back to molar are
26
Q

what to do when placing sensor if patient has tori

A

Edge ease

27
Q

sensor for mandibular premolar

A

Size 2 horizontal

28
Q

Location of sensor for mandibular premolar

A

Close to teeth

parallelto lingual surface of mandibular teeth

29
Q

Sensor for mandibular molar

A

size 2

horizontal

30
Q

Location of senor for mandibular molar

A

Close to teeth

parallel to lingual surface of teeth

31
Q

how to place a horizontal bitewing

A

between tongue and teth with tab resting on teeth
wire on other side of mouth
patient closes teeth and as closing swing the front edge of the aiming device to lateral incior to open contacts

32
Q

sensor for premolar bitewing

A

size 2 horizontal or vertical

33
Q

sensor for molar bitewing

A

Size 2 horizontal or vertical

34
Q

what do you do if sensor canot be placed parallel

A

USe bisecting angle technique

35
Q

when is the image still adequate when angulating sensor

A

No greater sensor angle of 20 degrees in relation to long axis
beam directed at 90 degrees to the sensor

36
Q

can a digital image be ajusted after exosure

A

No (several factors needed for good image)

37
Q

what is critacl to a diagnositc digital image

A

Quality control of technical factors and sensor positioning

38
Q

cause of overlap

A

Incorrect horizontal angulation

39
Q

Cause of incisal edge not being visible

A

Incorrect sensor placemnt

40
Q

Cause of elongation

A

Decreaesd vertical ingulation

41
Q

Cause of foreshortening

A

Increased vertical angulation

42
Q

cause of blurred image

A

Movement

43
Q

Cause of cone cut

A

X-ray beam not centered on receptor

44
Q

Cause of underexposre

A

less exposure

45
Q

CAuse of PSP plate articats

A

Scratched paltes

Plates not erased

46
Q

what is foreshortening and its cause

A

Teeth seems smaller since vertical angulation is too large

47
Q

what is elongation and cause

A

Teeth look too long due to verttical angulation being too little

48
Q

the max amount of electrons a pixel can hold

A

Full Well Capacity (Depends on CCD type)

49
Q

the process of Oversaturating the CCD

A

Blooming

50
Q

How does Blooming occuring

A

saturated pixels flow intoneighboring cells

51
Q

how to stop static

A

moisten cotton swab with rubbing alcohol and wipe USB and sensor connection

52
Q

what can static cause

A

Autofiring and self triggers to produce multiple blank images

53
Q

Tips to maximize comfort

A

Set everything up before placing in patient
Start with anterior
USe cotton rolls and eddge ease
place sensor skillfully
