Accepted Answer

"BAI" refers to bisecting angle instrument.

Question 2

According to the text,when exposing the anterior teeth using the bisecting technique,there are ________ recommended size 2 periapical receptor placements.

Accepted Answer

With a size 2 receptor,a total of six anterior receptor placements are used in the bisecting technique.

Question 3

With the ____________ technique,the vertical angulation is determined by the imaginary bisector;the central ray is directed perpendicular to the imaginary bisector.

Accepted Answer

With the bisecting technique,the vertical angulation is determined by the imaginary bisector;the central ray is directed perpendicular to the imaginary bisector.

Question 4

When the bisecting technique is used,the central ray is directed at 90 degrees to the

Accepted Answer

When the bisecting technique is used,the central ray is directed at 90 degrees to the imaginary bisector.

Question 5

(1)When using the bisecting technique,the receptor holder or the patient's finger may be used to stabilize the receptor.(2)A beam alignment device is used to stabilize the receptor and to align the position-indicating device (PID).

Accepted Answer

When using the bisecting technique,a receptor holder may be used to stabilize the receptor.The patient's finger should not be used.A beam alignment device is used to stabilize the receptor and to align the position-indicating device.

Question 6

The recommended anterior periapical exposure sequence for the bisecting technique starts with the

Accepted Answer

The recommended anterior periapical exposure sequence for the bisecting technique starts with the maxillary right canine.

Question 7

When the bisecting technique is used,which of the following angles is bisected?

Accepted Answer

The angle formed by the receptor and the long axis of the tooth is the angle that is bisected when the bisecting technique is used.

Question 8

When the bisecting technique is used,foreshortening will occur if the central ray is directed perpendicular to the

Accepted Answer

When the bisecting technique is used,foreshortening will occur if the central ray is directed perpendicular to the plane of the receptor.

Question 9

You are using the Rinn Snap-A-Ray to take a dental image of tooth #13.What vertical angulation should you set the PID at to get a dental image that is the same length as the tooth?

Accepted Answer

With the bisecting technique,the recommended vertical angulation range for mandibular premolars is -10 to -15 degrees.With the bisecting technique,the recommended vertical angulation range for maxillary molars is +20 to +30 degrees.With the bisecting technique,the recommended vertical angulation range for maxillary premolars is +30 to +40 degrees.Setting the vertical angulation is required with the Snap-A-Ray because there is no alignment rod or ring.

Question 10

Which of the following techniques use the same principles of horizontal angulation?
1)Paralleling
2)Bisecting
3)Bite-wing

Accepted Answer

Paralleling,bisecting,and bite-wing techniques all use the same principles of horizontal angulation.

Question 11

Receptor should be placed approximately ____ inch beyond the incisal or occlusal surfaces when using the bisecting technique.

Accepted Answer

The receptor should be placed approximately 1/8 inch beyond the incisal or occlusal surfaces when using the bisecting technique.

Question 12

The primary benefit of using a collimator on a Rinn BAI instrument with the bisecting technique is

Accepted Answer

The primary benefit to using receptor holders with the bisecting technique is reducing the patient's exposure to radiation.

Question 13

The rule of isometry states that two triangles are equal if they have ______ equal angle(s)and share a common side.

Accepted Answer

The rule of isometry states that two triangles are equal if they have two equal angles and share a common side.

Question 14

When the bisecting technique is used,the receptor must be placed along the ________ surface of the tooth.

Accepted Answer

When the bisecting technique is used,the receptor must be placed along the lingual surface of the tooth.

Question 15

Which of the following commercially available receptor holders is recommended for one-time use only?

Accepted Answer

The Stabe bite-block is recommended for one-time use only.

Question 16

Elongated images refer to images of the teeth that appear __________.Elongation of images results from _____________ vertical angulation.

Accepted Answer

Elongated images refer to images of the teeth that appear too long.Elongation of images results from insufficient vertical angulation.

Question 17

Foreshortened images refer to images of the teeth that appear _________.Foreshortening of images results from ___________ vertical angulation.

Accepted Answer

Foreshortened images refer to images of the teeth that appear shortened.Foreshortening of images results from excessive vertical angulation.

Question 18

Which size receptor is traditionally used with the bisecting technique?

Accepted Answer

With the bisecting technique,#2 receptor is traditionally used for anterior teeth and for posterior teeth;#1 receptor is recommended for anterior teeth with the paralleling technique.With the bisecting technique,#2 receptor is traditionally used for anterior teeth and for posterior teeth;#1 receptor not used for posterior teeth,it is recommended for anterior teeth with the paralleling technique.With the bisecting technique,#2 receptor is traditionally used for anterior teeth and for posterior teeth.

Question 19

Which of the following commercially available receptor holders are recommended for use with both the paralleling and the bisecting techniques?
1)Rinn XCP instruments
2)Rinn BAI instruments
3)Precision receptor holder
4)Stabe bite-block
5)Snap-A-Ray receptor holder

Accepted Answer

Rinn BAI instruments,Stabe bite-block,and Snap-A-Ray receptor holder are recommended for use with either the paralleling or the bisecting technique.

Question 20

With the bite-wing technique,the vertical angulation is predetermined;the central ray is directed at ____ degrees to the occlusal plane.

Accepted Answer

With the bite-wing technique,the vertical angulation is predetermined;the central ray is directed at +10 degrees to the occlusal plane.
