Expose and Evaluate Flashcards
Intra oral - show’s full tooth from cusp to apex - used to evaluate for periodical pathology/periodontal disease.
periapical
Intra oral - shows crowns, portion of roots of both maxillary and mandibular teeth on one film - used to detect inter proximal decay
bitewing
Intra oral - shows large portion of ONE JAW - detects impacted canines, jaw fractures, salivary stones
occlusal
Extra oral - shows full maxillary/mandibular arches on one film - evaluates position of 3rd molars, supernumerary teeth, TMJ, maxillary sinus, jaw fractures, edentulous arches - not detailed enough to diagnosis cries/periodontal disease
panoramic
Extra oral - lateral view of skull with soft tissue facial profile - used mainly in orthodontics - evaluates normal growth/development
cephalometric
Extra oral - used to evaluate the posterior region of the mandible - used in children/patients with limited jaw opening - evaluates impacted teeth/fractures/impacted 3rd molars - can be used to evaluate body of the mandible/ramus
lateral jaw
Extra oral - used to evaluate sinuses
water’s projection
Extra oral - used to evaluate facial growth/development/trauma/disease/developmental abnormalities

Radiographic techniques & their purpose:
film holders / bite blocks
stabilize film, prevent movement
Radiographic techniques & their purpose:
cotton rolls
stabilize film, patient comfort, prevent movement
Radiographic techniques & their purpose:
bitewing tabs
stabilize film, patient comfort, prevent movement
Radiographic techniques & their purpose:
lead apron
patient protection / used for all intra oral and extra oral exposures
Radiographic techniques & their purpose:
thyroid collar
patient protection / used for all intra oral exposures ONLY
What film size & radiographic technique is used for pediatric patients?
hint: intra oral films
0 / bitewing and periapical
What film size & radiographic technique is used for narrow anterior on adults?
hint: intra oral film
1 / anterior periapical
What film size & radiographic technique is more commonly used on adults and kids?
hint: Adults - anterior & posterior 2 intra oral films / Kids - periapical film
2 / Adults - periapical & bitewing / Kids - Occlusal
What film size is barely used on adults when doing a long bitewing?
3
What film size is used for occlusal on adults?
4
What determines film speed?
hint: 3 things
size of silver halide crystals / thickness of emulsion / presence of radiosensitive dye
True or False
less radiation is need to expose radiographs on an edentulous patient
true
causes film to fog
temperature
when too much, it will cause film to fog
humidity
true or false
Radiation protection - films should not be stored in areas where patients are exposed to radiation exposure to scatter radiation causes film to fog
true
supervision of supply
inventory control
new supplies should be placed…
at the bottom or in the back
old items should be used…
first so that supplies do not expire
