3. DENTAL X-RAY Dental X-rays  are pictures of the teeth, bones, and soft tissues around them to help find problems with the teeth, mouth, and jaw.  X-ray  pictures can show cavities, hidden  dental  structures (such as wisdom teeth), and bone loss that cannot be seen during a visual examination . Dental radiographs (X-rays) can provide important information about a patient's oral health. They help dentists examine the underlying bone, the roots of the teeth or unerupted teeth, as well as the contact areas where teeth touch one another.

4. COMPONENTS OF THE DENTAL X-RAY MACHINE The Control Panel - The portion of the x-ray machine that houses the major controls. Includes the line switch, timer, milliamperage & kilovoltage selectors, & the exposure button .

5. The Extension Arm - Flexible arm from which the tube head of the x-ray machine is suspended . The tube head is attached to the metal extension arm by means of a yoke that can revolve 360 degrees horizontally where it is connected.

6. The Tube Head - Protective metal covering that contains the x-ray tube, the high-voltage & low-voltage transformers, & insulating oil. Attached to the flexible extension arm by a yoke.

7. Advantages: Intraoral X-rays are the most common type of radiograph taken in dentistry. They give a high level of detail of the tooth, bone and supporting tissues of the mouth. These X-rays allow dentists to: Find cavities Look at the tooth roots Check the health of the bony area around the tooth Help diagnose periodontal disease See the status of developing teeth

8. Disadvantages: Women who are pregnant or believe they may be pregnant should avoid all types of X-rays. Tell your dentist if you believe you are pregnant, because radiation is not considered safe for developing fetuses.

9. Types of X-ray Procedures: Panoramic Bite-Wing Periapical Occlusal

10. Panoramic Dental X-ray Panoramic radiography, also called panoramic x-ray, is a two-dimensional (2-D) dental x-ray examination that captures the entire mouth in a single image, including the teeth, upper and lower jaws, surrounding structures and tissues. The jaw is a curved structure similar to that of a horseshoe. It usually provides details of the bones and teeth. An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging.

12. What are some common uses of the procedure? A panoramic x-ray is a commonly performed examination by dentists and oral surgeons in everyday practice and is an important diagnostic tool. It covers a wider area than a conventional intraoral x-ray and, as a result, provides valuable information about the maxillary sinuses, tooth positioning and other bone abnormalities. This examination is also used to plan treatment for full and partial dentures, braces, extractions and implants. A panoramic x-ray can also reveal dental and medical problems such as: advanced periodontal disease cysts in the jaw bones jaw tumors and oral cancer impacted teeth including wisdom teeth jaw disorders (also known as temporomandibular joint or TMJ disorders) sinusitis

13. What are the benefits vs. risks? Benefits No radiation remains in a patient's body after an x-ray examination. X-rays usually have no side effects in the typical diagnostic range for this exam. Panoramic x-rays can be used for very young children since the film does not have to be placed inside the mouth. Risks Women should always inform their dentist or oral surgeon if there is any possibility that they are pregnant. See the Safety page for more information about pregnancy and x-rays.

15. Bitewing Dental X-ray This technique involves biting down on a special piece of paper so your dentist can see how well the crowns of your teeth match up. This is commonly used to check for interdental cavities . This technique involves biting down on a special piece of paper so your dentist can see how well the crowns of your teeth match up. This is commonly used to check for interdental cavities.

16. Occlusal Dental X-ray Offers a clear view of the floor of the mouth to show the bite of the upper or lower jaw. This kind of X-ray highlights children’s tooth development to show the primary (baby) and permanent (adult) teeth . This X-ray is done when your jaw is closed to see how your upper and bottom teeth line up, and can also detect anatomical abnormalities with the floor of the mouth or the palate.

17. Periapical Dental X-ray This technique focuses on two complete teeth from root to crown . Provides a view of the entire tooth, from the crown to the bone that helps to support the tooth.
