Straight facial angle
When taking radiographs of mandibular premolars, which cone angle is recommended?
Mesial angle
What is the suggested cone angle for capturing radiographs of mandibular molars?
Distal angle
For which type of teeth should the mesial cone angle be utilized during radiographic examination?
Maxillary premolars and molars
Which horizontal cone angulation should be employed when capturing radiographs of mandibular incisor teeth?
Distal angle
What imaging technique provides anatomic features in 3D that intraoral and panoramic images cannot?
"CBCT" (Cone Beam Computed Tomography)
What is recommended to prevent subjecting the patient to unnecessary radiation exposures?
Taking two pre-treatment images from different angulations
In which case may additional exposures be necessary according to the text?
To determine the presence of multiple roots and canals
Which technique involves placing the film parallel to the long axis of the teeth?
Paralleling technique
What is the most practical source film distance used in most dental offices?
16 inches
What is the main reason for using different angulations for pre-treatment images?
To minimize radiation exposure
Why is it important to increase the object film distance in radiography?
To reduce radiation exposure
What is one major advantage of using the paralleling technique for periapical radiography?
Improved accuracy of images
Why is the paralleling technique difficult to use in patients with a shallow vault?
Challenges with positioning the X-ray sensor parallel to the tooth and film
Which disadvantage is specifically associated with the bisecting angle technique for periapical radiography?
Cone cutting
What does the bisecting angle rule state regarding the direction of the central ray in intraoral radiography?
Directed perpendicular to a line bisecting the angle formed by the plane of the long axis of the tooth and plane of the film
How do radiographs assist in endodontics?
By helping identify abnormalities like root curvature and canal calcifications
Which statement is true regarding periapical radiography techniques in endodontics?
Bisecting angle technique can cause superimposition of anatomic structures
