|---|---|---|---|---|---|
| The exposure time for a radiograph on an edentulas pateint should be | decreased 25% (25%less)
🗑
|
||||
| the following would not be used in a survey of an endentulous patient | inteproximal radiographs
🗑
|
||||
| dot in the slot means | the indentification dot should be toward the occlusail or incisal suface when exposing x-rays
🗑
|
||||
| T or F non critical instruments are used to penetrate soft tissue and bone must be sterilized | true
🗑
|
||||
| when the interproximal space on the radiograph are overlapped, what is the error the result of | horizontal angulation
🗑
|
||||
| the maxillary premolar periapical shows openpremolar contacts but does not show distal portion of the canine. to correct this error, the operatior should... | place the flim more to the anterior
🗑
|
||||
| foreshortening of a tooth in a radiograph is caused by | the vertical angle being too steep
🗑
|
||||
| blurred radiographs may be caused by | movement during exposure
🗑
|
||||
| the long cone technique in dental radiographs is used to | produce improved detail and image sharpness, increases anatomic accuracy, decrease image magnification and enlargment,decrease distortion
🗑
|
||||
| On periapical x-rays the amount of observable bone beyond the apices should be | 2 milimeter
🗑
|
||||
| You change the target flim distance from short cone to a longcone. If flim of the same speed were used in two exposure, based on the inverse square law, what exposure factor would have to be changed? | exposure time should be increased four fold
🗑
|
||||
| when taking bitewing radiograph with tabs the mid sagittal plane of the mid sagittal plane of the patients head should be | perpendicular to the floor, the vertical angle
🗑
|
||||
| elongationof the image an maxillary radiograph may be caused by | not enough vertical angulation, and poor patient position
🗑
|
||||
| which combinations XCP indicator arms aiming rings, bite blocks, and flim are designed to be used to expose posterior periapical radiograph | remember ACFG
🗑
|
||||
| when making a dental x-ray flim exposure accourding to the bisection of the angle technique which of the following procedures would be correct | the central x-ray beam is directed perpendicular to the imaginary plane bisecting the angle formed by the flim and the tooth
🗑
|
||||
| what is another term of the long-cone technique of dental radiography | paralleling techinique
🗑
|
||||
| Cone cutting is caused by | Misalignment of the X-ray beam
🗑
|
||||
| the occlusal plane on a molar bitewing is recorded diagonally rather than horizontally. In order to correct this, the operator must... | change the placement of the film
🗑
|
||||
| a postoperative radiograph of a mandibular left cuspid shows an endodontic file protruding from the apex. The error in measuring the tooth length was most likely the result of the preoperative radiograph having been made with... | excesive vertical angulation
🗑
|
||||
| the image on a processed radiograph is elongated. to correct this error you must... | steepen (increase) vertical angulation
🗑
|
||||
| an interproximal radiograph would show... | the crowns of the teeth in both arches, recurrent and incipient interproximal caries, and alveolar crest resorption (bone loss)
🗑
|
||||
| what could cause the density of a radiograph to be too light... | underexposure, film backwards, underdevelopment, and/or not enough pressure on exposure switch
🗑
|
||||
| proper horizontal angulation involves directing the central beam... | through the contact areas of two adjacent teeth and at a right angle to the film
🗑
|
||||
| a film packet was placed backwards in the oral cavity. the resulting radiograph will... | be lighter than the other radiographs, and have a herringbone (tire track) pattern
🗑
|
||||
| a maxillary radiograph does not show the apices of the teeth. this may be caused by... | insufficient vertical angulation, and laying the film too flat
🗑
|
||||
| which of the following is NOT a film holder for use in paralleling technique... | VIP
🗑
|
||||
| appropriate infection control procedures during x-ray exposure should include... | using barrier protection (plastic bag) over the tubehead
🗑
|
||||
| the following describes the relationship of the film and the long axis of the tooth in the paralleling technique... | the film and tooth are parallel to each other
🗑
|
||||
| when using bite wing tabs, on a posterior interproximal radiographs, what is the correct vertical angulation... | +10 degrees
🗑
|
||||
| the following describes the distance between the film and the tooth in the bisecting technique... | the film is placed as close as possible to the tooth
🗑
|
||||
| while using the bisecting technique, you expose a mandibular cuspid film at negative 5. To correct the error you should... | increase the vertical angle to negative 20
🗑
