Pediatric Dental X-ray Types

Dental x-rays are an essential part of any dental care treatment plan. They are diagnostic, but they can also be preventive, by helping a dentist diagnose potential oral care issues in a patient’s mouth before they become a major problem.

There are five types of X-rays your dentist may use for your child, depending on the goal:

* Bitewing X-rays (also called cavity-detecting X-rays) — These X-rays are used to view the areas between teeth that cannot be seen directly. They show where cavities are starting. These X-rays are needed only after the teeth in the back of the mouth are touching each other. In some children, this doesn't happen until the first permanent molar (also called the 6-year molar) has erupted.

* Periapical X-rays — These are used to view the entire crowns and roots of one, two or three teeth that are next to each other. The X-rays also will show the supporting bone structure of the teeth. This type of X-ray lets the dentist see a child's permanent teeth growing below the baby teeth. It also is used to look for abscesses and gum disease.

* Panoramic X-rays — These X-rays are used to view all of the teeth on one film. They also show the upper and lower jaws, the temporomandibular joints (TMJs) and the sinuses above the upper teeth. They are often used if a child has hurt his or her face, has orthodontic problems, or is mentally or physically disabled. Panoramic X-rays, unlike other types, do not require a film to be put in the child's mouth. This is helpful for children who gag easily or who have small mouths. This X-ray has to be exposed for 12 to 18 seconds. The patient must be able to sit or stand still for that whole time.

* Occlusal X-rays — These are used to view most of the upper or lower teeth on one film. This is useful when the dentist does not have a panoramic X-ray machine or when the child has difficulty in taking bitewing or periapical X-rays.

* Orthodontic X-rays (also called cephalometric or lateral skull) — This type of X-ray shows the head from the side. It is used to evaluate growth of the jaws and the relationship of bones in the skull. It helps an orthodontist make an accurate diagnosis and develop a treatment plan.

Dental X-rays are very safe and expose your child to a minimal amount of radiation. When all standard safety precautions are taken, today's X-ray equipment is able to prevent unnecessary radiation and allows the dentist to focus the X-ray beam on a specific part of the mouth. High-speed film enables the dentist to reduce the amount of radiation the patient receives. A lead body apron or shield will be placed over the child's body. Make sure the shield covers your child's neck to protect the thyroid gland. It also should extend all the way to the thighs to protect the genitals and reproductive organs.

Oral Injuries and Their Treatment in Children

Besides tooth caries and misaligned teeth, very few children make it through to childhood without mouth injuries. The appearance of teeth in children brings with it a whole set of problems. While some are predictable, some others aren't. 

Mouth injuries, even the most gory ones need immediate and good treatment to avoid any permanent kind of damage. While home treatment often suffices, medical intervention is required in certain extreme cases. Below is all what you need to know to differentiate between the two.

How they happen?

Besides scraped knees and head bumps, cuts and bleeding on lips and inside of the mouth is very common in children. Mouth tissues are soft, and often a fall or hit pushes them against hard bones of the jaw or even the teeth. In addition, slip ups, tumbles, crawling are all activities where a child's mouth is exposed, leading to cuts and bruising.

How to treat them?

Oral injuries in children look much worse than they actually are. Because the mouth and areas in the face and head are suffuse with blood vessels, even a tiny cut can cause excessive bleeding, with the exact location becoming difficult to pinpoint. Often mouth injuries are minor and the crying bouts of the child are more out of fear than actual injury.

The below steps will help you handle any kind of mouth injury in a calm manner, reduce bleeding, minimize the pain and prevent infection.

• Stop the Bleeding - If the bleeding is from the outer lip or tongue, apply gentle pressure on the area with a clean moist cloth for a while. If inner lip bleeds, press the area gently against the child's teeth/gums.
• Distract the child during cleaning- Sing, talk or soothe the child in whichever way you can. Any treatment needs a child to sit still.
• Keep the area cool - Numbing the pain and reducing the swelling are first priority. Apply an ice pack or frozen veggies on the area. Sucking a Popsicle is also a great idea.
• Painkiller - These should be given only when the child is unable to bear the pain for long, usually under advice from the pediatric dentist
• Change diet temporarily - Although often superficial, lip cuts or injuries can be very painful. It is better to change the diet for children to liquid or semi-solid till the wound heals. Softer diets help healing faster and don't tend to irritate. Chilled treats such as Popsicle or ice cream, and a mouth rinse after food will take care of dental hygiene too for a while.

When is a pediatric dentist intervention necessary?

• When bleeding is very heavy, continuous and uncontrolled, and doesn't stop despite applying pressure and ice.
• When the cut is too deep or too wide
• When a rusted or dirt filled object has caused the wound
• When there is dirt or mud in the wound
• When a puncture wound caused due to pen/pencil gets into the roof of the mouth, or hurts deeper tissues of the jaw
• When the wound is caused by bite of an animal
• If there is suspicion of bone injury, swelling of the jaw, locked jaw, broken or impacted tooth
• Any inflammatory changes such as redness, swelling, pain, fever that lasts for more than a day

It is very common for children to have mouth injuries, almost like a rite of passage in childhood. The right kind of treatment immediately, with moral support and without anxiety will help them recover faster.
