Topic: Permanent teeth


  
  AllRefer.com - teeth (Anatomy And Physiology) - Encyclopedia
teeth, hard, calcified structures embedded in the bone of the jaws of vertebrates that perform the primary function of mastication.
The last of the permanent teeth (wisdom teeth) may not appear until the 25th year, and in some persons do not erupt at all.
Proper diet is necessary for the development and maintenance of sound teeth, especially sufficient calcium, phosphorus, and vitamins D and C. The most common disorder that affects the teeth is dental caries (tooth decay).

 The Eruption of Permanent Teeth
Teeth are formed in the jawbone, and must grow through the bone and covering gum into the mouth.
The permanent teeth start erupting from the age of 6, and by the age of 13, all the baby teeth have been replaced.
Teeth are prevented from growing longer by their contact with teeth in the opposite jaw.

 Primary & Permanent Teeth
Primary teeth maintain the spaces where permanent teeth will erupt and help develop proper speech patterns that would otherwise be difficult without maintenance of the space; crowding and misalignment can occur, resulting in more complicated treatment later.
Your child's primary teeth generally make their appearance when he or she is six or seven months old, though it can occur as early as birth.
Primary teeth fall out because permanent teeth are pushing them, and by about age 14 children have a full set of 28 permanent teeth, plus four additional teeth, called wisdom teeth that grow behind the permanent teeth in late adolescence for a total of 32.

If the teeth are severely crowded, it may be clear that some unerupted permanent teeth (usually the canine teeth) will either remain impacted (teeth that should have come in, but have not), or come in to a highly undesirable position.

In about three out of four cases where teeth have not been removed during orthodontic treatment, there are good reasons to have the wisdom teeth removed, usually when a person reaches his or her mid- to late-teen years.

 NGC - NGC Summary
Pulpectomy in permanent teeth is conventional root canal (endodontic) treatment for exposed, infected, and/or necrotic teeth to eliminate pulpal and periradicular infection.
For root canal-treated teeth with unresolved periradicular lesions, root canals that are not accessible from the conventional coronal approach, or calcification of the root canal space, endodontic treatment of a more specialized nature may be indicated.
Apexification is a method of inducing root end closure of an incompletely formed nonvital permanent tooth by removing the coronal and nonvital radicular tissue just short of the root end and placing in the canal a suitable biocompatible agent such as calcium hydroxide (several treatments with a fresh agent may be necessary) or MTA.

 Berkeley Parents Network: Missing Permanent Tooth   (Site not responding. Last check: 2007-10-29)
Other commonly missing teeth are the upper front ''lateral'' incisors (the ones on either side of the 2 front teeth) and the lower premolars.
In the past, the common school of thought was to orthodontically move the adjacent teeth into the space of the missing teeth and then reshape them to resemble the appearance of the missing tooth contour.
This results in the most conservative and longest lasting approach because the teeth are kept in their natural position in the arch and are not altered or compromised by crowns or bonding.
