Paralleling Techniqu

Dental Radiography -- Principles and Techniques

Paralleling Technique also known as XCP technique, right angle technique, long cone tchnique
Principles of Paralleling Technique 1. Receptor placed in mouth parallel to long axis of tooth 2. CR is perpendicular to receptor and long axis of tooth 3. PT cannot hold receptor
Object-receptor Distance distance between receptor and tooth must b increased to keep receptor parallel w long axis of tooth
Target-receptor Distance distance btwn source of x-rays and receptor must b increased to ensure only most parallel rays will b directed at tooth and receptor
Shallow Palate tilting bite-block occurs = lack of parallelism cotton rolls can b placed on either side of bite block increase VA by 5-15 degrees
Bony Growths MX tori -- receptor must b placed on far side MD tori -- receptor must b placed btwn tori and tongue
MD PM Region Ant floor of mouth is sensitive - receptor must b placed under tongue
Advantages of Paralleling Technique - produce radiographs w/o dimensional distortion - uncomplicated - accuracy - duplication is easy
Disadvantages of Paralleling Technique - receptor placement - discomfort for PT
