| if you see maxillary sinus on an x-ray is | located maxillary posterior PA's |
| if you see ramus on an x-ray | mandibular molar radiograph |
| nasal septum on an x-ray | maxillary anterior radiograph |
| dilaceration means | a sharp bend in the root |
| stand how many feet behind a lead wall | 6 feet |
| what is the error if x-ray is too dark | too much exposure or developer solution was too warm |
| cells susceptible to radiation damage | rapidly dividing undefined cells |
| bisecting angle technique | forms angle between the axis of the tooth and film |
| safelight in the darkroom | minimum of 4 feet away from working surface |
| the ph of processing chemicals | developer is alkaline and fixture is acidic |
| dispose the lead foil from the film packet in the regular garbage | NEVER |

| the ghost image on a panx | patient did not remove glasses, jewelry, dentures, and retainer |
| static electricity lines on an x-ray | are branch looking thin black lines |
| proper radiograph shows | incisal/occl surface, root and 2-3 mm of the bone surrounding the apex of the tooth |
| when an x-ray appears clear | there was no radiation exposure |
| radiopaque means | the images of a processed radiograph appears white/light |
| ALARA | as low as reasonable achievable |
| human erythema | is an example of a threshold level |
