| Term | Definition |
| 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 |
