Dental X-Rays For Your Child

Parents often question the need for dental X-rays (radiographs or films). Just as a broken bone or lung disease require a radiograph for a diagnosis, dental decay or other pathology (disease) of the oral cavity may require a radiograph for diagnosis. Tooth decay in children spreads rapidly in primary (baby) teeth.

Bitewing Radiograph(s)

These films, usually two, identify the presence of decay between the back (posterior) teeth. Decay between the teeth is called interproximal decay. By four and one-half years of age, the baby (primary) molars usually touch or contact each other. Interproximal decay can spread to the adjacent tooth if the teeth are in contact. If there are spaces between the primary molars, and there is no other evidence of decay, these films may not be necessary until later. A lack of spacing between the primary teeth predisposes a child to a much higher incidence of interproximal decay. Early detection permits your dentist to restore (repair) the tooth in less time and preserve tooth structure.

Periapical x-Ray

This film is used to examine the area around the tip of the root(s) or in between the roots. Primary teeth have long roots before they are resorbed (dissolved) by the pressure of the erupting permanent tooth. A root fracture after trauma, deep decay, infection, the need for root canal treatment, the presence of extra teeth, or absence of developing teeth are some of the findings with this film.

Occlusal Radiograph

This film evaluates the presence or absence of the upper and lower front teeth (incisors). It may also be used to diagnose fractures of teeth or bone and extra or missing teeth.

Panoramic x-Ray

Some pediatric dentists request this film around seven or eight years of age, when all eight permanent incisors have erupted. Although this not as accurate in diagnosing decay, it may provide an alternative if a child has a gag reflex that has prohibited taking a periapical or bitewing radiograph. The film is outside the mouth in a machine that revolves around the head. A view of the entire upper and lower jaw is obtained. This is commonly obtained by orthodontists prior to treatment. The panoramic radiograph may reveal or evaluate:

• Missing teeth
• Extra teeth
• Tumors, cysts, or other disease
• Improper position of teeth
• Broken bones after trauma
• Development of the permanent teeth
• Future crowding
• Wisdom teeth

Cephalometric Radiograph

This film ordinarily is obtained by an orthodontist in order to make a diagnosis of a child's bite (occlusion) and to determine the best treatment plan. It measures the relationship of the bones of the head and jaws.

Now, you are "in the know" for your child's next dental X-rays!

Children's Speech Problems

What did you say?

We've all heard young children speak "baby talk." Sometimes it can sound endearing — it may be a speech defect.

In early infancy, babies begin to make vowel sounds, usually mastered by age three, when they are finished teething. Consonant sounds are more difficult and come a little later on. By the eighth birthday, most children can pronounce all consonants and are 100% intelligible. But some children have more difficulty with speech and may need help learning.

• Lisping — The most common speech defect is lisping, which is relatively easy to correct. Children who lisp cannot produce "s," "z," "sh," "ch," and "j" sounds. A lisp is heard when children cut off an "s" with the tongue instead of the front teeth. Prolonged thumb sucking or finger sucking can create an open bite and result in a lisp. Other causes are the loss of a primary tooth, impaired hearing, undeveloped ability to discriminate sounds, imitation of a relative or friend who lisps, or neurological disturbances.
• Cleft palate — A cleft palate can dramatically affect a child's speech, and often requires oral surgery. Sometimes an orthodontist provides a plastic plate to cover the opening in the roof of the mouth — this allows the child to develop normal speech patterns until surgery can correct the palate.
• Tongue thrusting — Tongue thrusting is another problem that can impair speech. This is essentially "reverse swallowing," and can cause improper tooth alignment. It may result from prolonged thumb sucking, which leaves a gap between the teeth and fosters the habit.

Your pediatric dentist may notice a speech problem first. The dentist often works with a team, including a speech pathologist, orthodontist and oral surgeon, to correct the speech problem. Your family dentist can let you know if they think anything is amiss with your child's developing speech patterns.
