Dental Equipment

Radiography
Diagnostic radiography describes the use of X-rays to create images of interior body structures. There are
three types of diagnostic radiographs taken in today's dental office: intraoral (bitewings and periapical views),
panoramic, and cephalometric images.

Panoramic ("pan"): Recommended
Panoramic X-rays generate a 5" x 11" (15cm x 30cm) wrap-around image of the
patient's mouth. This is useful for studying the patient's jaw, the position of the teeth
relative to one another, facial and jaw injuries, and even arterial blockages to the head.
The pan machine usually occupies its own small alcove in the dental office. Digital
pan machines instantly acquire the image and then transfer it to the designated
computer monitor to be viewed. Patients will notice no difference in how they
experience the process.
Because of the many ways in which panoramic images enhance diagnosis, we recommend you allow for the
addition of a pan in the future if you have insufficient funds initially.

Cephalometric ("ceph"): Recommeded for Orthodontics
Ceph X-rays capture a radiographic image of the entire head, usually in profile. Orthodontists use these images
most frequently for diagnosing misalignment of teeth and bite problems. Ceph images require a panoramic
machine outfitted with a cephalometric arm mounted off to one side. When you decide on a ceph machine,
you will need to choose whether the ceph arm needs right or left positioning. Some panoramic machines may
be upgraded to accommodate a ceph arm while others cannot. If you are considering growing your program
over time but plan to only start with a pan machine, make sure that your panograph can be upgraded to ceph
capability in the future.

Intra-Oral X-ray Unit: Essential
Best located in the operatory and discussed in operatory equipment. See "Essential Equipment" above.

Digital Radiography
Digital radiography electronically captures, loads, stores, and enhances diagnostic
images. There are two types of digital radiography: direct digital and phosphor plate.
A direct digital system uses wired sensors, which are placed in the mouth in lieu of
film. The sensors connect directly to the computer system and give an instant image.
When taking a full-mouth series, the same sensor is moved from one position to the
next in the patient's mouth, without any need to change or erase the sensor. Sensors
work well for virtually all patients and manufacturers provide excellent positioning
systems to help staff correctly place the sensors for good diagnostic results and
optimal patient comfort.
There are two key types of digital sensors sizes. DEXIS produces a sensor that is essentially the size of
traditional child film but which has an imaging size that is approximately equal to adult film. This sensor
