Electroodontodiagnosis in orthodontics

A significant role is played by electroodontodiagnosis in orthodontics. Study of influence of orthodontic treatment for elektrovozoremontnij teeth have been studied by many authors (I. I. Postolachi, 1967; 3. P. Chirac, 1968; A. A. Anikienko, L. I. Kamysheva, A. P. Panina, 1969; Kuligowski, Mitrega, 1965, and others). Their research showed that electroodontodiagnosis is a very important criterion in assessing the effectiveness of orthodontic treatment.
So, for example, 3. P. Chirac investigated the changes of elektrovozoremontnij 1015 teeth in children (aged from 7 to 15 years) with various anomalies of the dental arches.
The study orthodontic loaded teeth were performed before treatment and at certain periods after treatment. Some teeth definition of elektrovozoremontnij was carried out after 1-3 weeks load, others - after load within 1-6 months, and at the third - after 7-24 months. The lower incisors not established any significant changes of excitability, and at the top is a small increase of the threshold. This can be explained by the relatively larger burden of the upper teeth during treatment. Similar, but more expressed human elektrovozoremontnij marked in the upper incisors and especially in canines after 1-6 months orthodontic treatment. The scan results after 7-24 months orthodontic load showed that after coming in the first months of a decrease in excitability further treatment is no longer affects the threshold of excitability.
Studying the dynamics of changes of elektrovozoremontnij depending on orthodontic load, the author did not take into account the fact that she had to deal with teeth that are at different stages of development, and that this in itself affects the threshold elektrovozoremontnij.
A. A. Anikienko, L. I. Kamysheva and A. P. Panina (1969) studied the effect of orthodontic apparatus action on elektrovozoremontnij teeth. These authors determined elektrovozoremontnij 282 of intact teeth for orthodontic treatment 49 people (aged 12-33 years)who have had a narrowing of the dentition. The expansion was performed using arcs Angle or expanding plates with screws. Research Avars have shown that these mechanical existing devices significantly alter elektrovozoremontnij lateral teeth and almost no effect on the group of front teeth; after orthodontic treatment elektrovozoremontnij gradually returning to normal.
However, these authors in the evaluation of their results also did not take into account dependence of the dynamics of changes of elektrovozoremontnij from the stage of development of the tooth.
We conducted in recent observations have shown that any orthodontic intervention should be under the control of electric diagnostics. The emergence of a decrease in excitability indicates overload relevant teeth. If the load time reduce, elektrovozoremontnij normalized. Failure to do so can lead to serious changes in the pulp, up to death.
