| 3 common types of radipgraph exams that use intraoral film are? | periapical examination, interproximal examination, occlusal examination |
| periapical exam is used to what? | examine the entire tooth and supporting bone |
| interproximal examination is used to what? | examine the crowns of both maxillary and mandibular teeth on a single film |
| occlusal film is used to what? | examine large areas if the maxilla and mandible on one film |
| tooth-bearing areas are? | areas that on the maxilla and mandible where the 32 teeth of the human dentition are normally located. |
| external radipgraphic examination is what? | exam of large areas of the skull of jaws |
| precipitating factors respondible for initiating the gag reflex inculde? | psychogenic stimuli, tactile stimuli |
| to effectivly manage a person with a hypersensative gag reflex, radiographer must be aware of... | operator attitude, patient and equiptment preparations, exposure sequencing, film placement and technique, helpful hints for preventing the gag reflex |
| of all film placements, which one is the most likely to cause a gag reflex? | maxillary molar |
| do not slide the film along what? | the palate |
| is the patient do what, the gag reflex ceases? | breathes |
| films for the primary dentition (3 to 6 years) | 1 occlusal max. film-size 2, 1 occlusal mand. film-size 2, 2 bitewings-size 0, 2 PA's max. molar-size 0, 2 PA's mand. molar-size 0 |

| why does an edentulus patient need x-rays? | to detect the presence of root tips, impacted teeth, and lesions; to identify objects embedded in bone, to establish the position of normal anatomic landmarks relative to the crest of alveolar ridge |

| after processing, fresh film that has been properly stored and protected will appear | clear with a slight blue tint |
| after performing the film-scren contact test, a wire mesh image of uniform density appears. these results indicate: | adequate film-screen contact |
| when functioning properly, a viewbox should emit a uniform and brilliant light. | false |
| the coin test is used to check? | proper safelighting |

| the clearing test is used to monitor? | fixer strength |
| true, false? skills that promote a good relationship between individuals are termed faciliation skills | false |
| informed consent is based on the concept that a patient revieves: | complete disclosure |
| the process of informing the patient about the particulars of exposing dental radiographs is termed: | disclosure |
| the right to self-determination means that the patient has the right to consent or refuse treatment: | true |
| improper exposure to dental radiographs may result in: | malpractice |
| it is best to retain dental records for 6 years | false |
| the central ray in the bisecing technique sould be: | 90 degrees to in imaginary bisector |
| the distance between the film and the tooth in the bisecing technique should be: | as close to the toot as possible |
| the lingual cusp of the first premolar usually obscures the distal contact of the canine in this shot. | maxillary canine exposure |
