Clinical and morphological assessment of low frequency ultrasound use in delayed eruption of teeth

Aim. Development of a new method stimulating eruption of impacted teeth, reducing side effects and the term of orthodontic treatment. Methods. Considering the high numbers of patients who sought medical aid with delayed eruption of teeth, rational method of low-frequency ultrasound was used for stimulating eruption of impacted teeth. The stimulation process was performed by «SIAZ-EGS Med-Stomo» device, with the oscillation frequency of 26.5 kHz, intensity of 1 W/cm, amplitude of 40-60 μm, a wavelength 0,012 m, developed in Azerbaijan. Clinical and morphological methods, including examination of gingival tissue biopsies from the area where low-frequency ultrasound was applied, were used. After clinical and radiographic examination and identifying the impacted tooth with a favorable location on dental panoramic radiography, if there was a space in the tooth row, the area of the tooth projection at the gum was directly affected by low-frequency ultrasound daily or every other day for 5-10 seconds. An average of 1-5 procedures up to the tooth eruption was performed. Results. Microscopy of epithelial cover and stroma proved the absence of inflammation, thickening of outermost layer on the gum surface. Cells of the intermediate layer revealed the intact nucleus, loosening with linear swelling and cell dissociation. Cellular and tissue changes in gingival tissue seen after the treatment with low-frequency ultrasound may indicate the boosting of the impacted teeth eruption due to the syndrome of molecular contusion, improving the microcirculation and loosening the gum tissues. Conclusion. The results of comprehensive orthodontic treatment using low-frequency ultrasound ito stimulate the eruption of impacted teeth may be recommended for practical use.

Background: Goal of the research was to study occurrence frequency of impacted teeth, to develop rational methods of diagnostics and treatment of denotalveolar and facial anomalies caused by impacted teeth. Patients and methods: From 1989 for 2013 period of time 7172 patients with dentoalveolar anomalies, referred to our clinic for the orthodontic help were surveyed. Results: At 899 (12,53±0,39%) patients it is revealed 1405 impacted teeth, from them on the maxilla — 623, on mandible — 752 teeth. The most widespread impacted teeth on the maxilla were canines, on the mandible — the second premolars and the third molars. Treatment of impacted teeth by stimulation of their eruption by low-frequency ultrasound with a frequency of fluctuations of 26,5 kHz, intensity of 1 W/cm, with an amplitude of 40–60 microns and wave of 0,012 m long, daily or within 1 days, with period of 3–10 seconds with the course of treatment averaging 1–5 procedures, until a tooth eruption is carried out. Conclusion: The way of stimulation developed by us for late erupted impacted permanent teeth on the basis of application physiologic for an organism low-frequency ultrasound promotes increase of efficiency and reduction of treatment terms of dentoalveolar and facial anomalies. The received positive results allow to recommend this method for adoption in orthodontic practice.

The article presents results of a study on the effectiveness of using lowfrequency ultrasound and photochromotherapy in the complex treatment of patients with chronic bacterial and viral rhinosinusitis. The study involved 69 people aged 18 to 55 years: 39 (56.83 %) women and 30 (45.11 %) men with chronic rhinosinusitis during the period of clinical exacerbation and concomitant chronic tonsillitis without exacerbation. All patients included in the study underwent X-ray examination or computed tomography and magnetic resonance imaging of the paranasal sinuses. 100 % of the patients were examined for the presence of antibodies to Human gammaherpesvirus 4 (ELISA), had study of blood serum for IgM and IgG and test to determine the avidity of Ig G antibodies to γ-herpesviruses. The obtained data indicate the effectiveness of including low-frequency ultrasound and photochromotherapy in the complex treatment of patients with chronic rhinosinusitis and concomitant chronic tonsillitis of bacterial and viral nature without exacerbation.

Impacted Teeth

Introduction: Impacted teeth is complex anomaly of teeth eruption that requires a balanced approach not only in the differential diagnosis of its forms, but choice of rational methods of treatment. The aim: Optimization of the tactics of orthodontic-surgical treatment of patients with impacted teeth based on the development and implementation of computed tomographic indices (KT) and photometric indices (FM) of opening of surgical access (OSA) to crowns of impacted teeth Materials and methods: The results of treatment of 48 patients with delay of permanent teeth eruption have been analyzed. For an objective assessment of treatment results, a group of 24 (aged from 9 to 19 years old ) was formed. All 24 patients had typical clinical situation. Results: Orthodontic correction of patients envisaged, first of all, the elimination of obstacles in the way of teeth eruption, if necessary to provide space in dental arch and simultaneous treatment of associated bite malocclusions. Surgical exposure of impacted tooth crown was carried out and at the same time a triangular shaped guiding channel was formed, base of channel was at the impacted tooth and its angle finished into the dental arch. Precise dimensions and depth of the channel were preliminary planed on computed tomography slices with 3D reconstruction. Mean values of CT width (7,13±0,54mm), and length (6,42±0,78mm) of OSA and CT index (130,79±8,19%) of OSA to impacted teeth crowns were determined. Conclusion: To improve the quality of diagnosis and optimization of methodological approaches to treatment of patients with teeth impaction, we have proposed CT and FM OSA indices to the crowns of impacted teeth. The developed indices serve as specific reference points for optimization of diagnostic process, for reducing of probability of repeated surgical interventions and choosing the optimal path for instrumental orthodontic treatment of patients with impacted teeth
