Periodontia (hyperdontia): anomaly supernumerary teeth

Anomaly supernumerary teeth or periodontia (hyperdontia) is not as rare as it might seem at first glance. According dentists suffers from it from 4 to 7 percent of the population of the planet.

This anomaly may cause serious inconvenience: problems with diction, bite and meal. In this article we will explain what is periodontia, name the main reasons of its occurrence and describe the symptoms and diagnosis of the disease.

Periodontia – what is it?

Periodontia is the appearance of a tooth row of a person an excessive number of teeth. From this disease affects mostly men, though among women the pathology to happen, often this disease appears in babies. A child is born with a tooth, but the rest of the tooth germ is also in place, in this case, parents are advised to get rid of the «extra» tooth in a child.

Excessive number of teeth in humans is not uncommon. As a rule, grows only one additional tooth, but there are two (about ¼ of all cases of periodontia), three or more. It should be noted that the third molars («wisdom teeth») should not be attributed to cases of periodontia, even though they appear not at all.

Reasons

Why may occur anomaly, supernumerary teeth? There are several reasons:

  • pathology of dental germs — such processes are developing when the fetus is in the womb. This happens because of failures in her system, which may be associated with adverse factors (e.g., ecology). According to scientists, the tooth Bud grows into several parts, which ultimately leads to abnormalities in the child;
  • failures in the genetic code — it is believed that the first people had four, and six incisors in each jaw. Scientists attribute this to the fact that in primitive times people ate no processed meat food, it required a large number of teeth, whose function is nibble pieces of food. Over time through evolution, the human body no longer need in such quantity of cutters. The occurrence of extra teeth in some people in our time, according to experts, is connected with the rest of the elements of the genetic code of ancient humans, but this is just a hypothesis.

However, the exact answer for the cause of this illness is not. The above reasons are just the most likely of the proposed science. Thus, the etiology of this disease remains quite mysterious.

  2. Atypical periodontia – supernumerary teeth grow out of the aisles of the dentition, they can appear in the sky and in other places. In unique cases, can erupt outside the mouth.
  3. Real periodontia featuring a classic cut and shape of supernumerary teeth. Their appearance do not go over the boundaries of the dentition.
  4. For about the form of the disease characterized by the increase in the number of teeth in an adult due to incomplete loss of milk teeth. The latter can remain in the tooth row for many decades after the alleged time of their loss. It happens that the presence of such supernumerary teeth does not even interfere with occlusion and does not cause any other forms of discomfort. Another symptom of false forms are fused between the teeth.
  5. Impacted supernumerary teeth — they don’t grow outward, but remain under the covering tissues of the mouth. As a rule, patients do not feel any discomfort, and find them only during a thorough examination or treatment of other teeth.
