Understanding Bisecting Angle Technique in Dental X-rays

The video tutorial by Sheri Ortiz and Vicky Romans explains the bisecting angle technique in dental x-rays. It covers the use of ring instruments to simplify the process, the importance of correct vertical tube angles to avoid errors like elongation and foreshortening, and how to use sensors effectively. The tutorial also discusses the role of bite wings and horizontal angulation in achieving accurate dental images. Practical tips and common mistakes are highlighted to help dental professionals improve their technique.

What is the primary purpose of using ring instruments in dental X-rays?

• To increase patient comfort

• To enhance the image quality

• To simplify the bisecting angle technique

• To reduce radiation exposure

What is the main goal of the bisecting angle technique?

• To increase the size of the tooth image

• To achieve the correct length of the tooth image

• To decrease the size of the tooth image

• To enhance the color of the tooth image

What error occurs if the vertical tube angle is too high?

• Blurring

• Overlapping

• For shortening

• Elongation

What is a common issue when using sensors for the bisecting angle technique?

• Sensors are too small

• Sensors are too fragile

• Sensors are too light

• Sensors are too bulky

How can you prevent a distorted image when using sensors?

• Use a smaller sensor

• Tip the sensor slightly

• Decrease the tube angle

• Increase the exposure time

What should be included in the film when using bite wings?

• The premolar and the space between the canine and first premolar

• The entire dental arch

• Only the molars

• Only the front teeth

What is the consequence of incorrect horizontal angulation?

• For shortening

• Blurring

• Elongation

• Overlapping

How can you ensure the X-ray beam hits the buccal surface at a right angle?

• By using a larger sensor

• By increasing the exposure time

• By adjusting the vertical tube angle

• By checking the shape of the arch

What is a common mistake when positioning the horizontal beam?

• Not using enough exposure

• Guessing the beam's direction

• Using a too high tube angle

• Placing the film too far back

What should you do if the film is not forward enough in the mouth?

• Increase the tube angle

• Wedge it slightly to the side

• Decrease the exposure time

• Use a larger film
