The authors present comparative analysis of the adhesive strength parameters of various ceramic coatings with a new Russian titanium-based alloy for metalloceramic dental prostheses. Basing on their data, the authors give recommendations on what ceramic coating is preferable to use in the production affixed orthopedic constructions on frames made of the new alloy.

The authors present the first study of the efficacy of electromagnetic radiation on the frequency of nitric oxide absorption and emission molecular spectrum in treatment of periodontitis. The use of the method resulted in certain clinical improvements (reduction in gum mucosal edema and hyperemia) and betterments in patients' sensations (pain and discomfort reduction). The cytokine profile (the ratio of pro- and anti-inflammatory cytokines: TNF-a, IL-8, IL-4) and the index of secretory A immunoglobulin normalized, which evidenced the efficacy of the therapy. An optimal regimen of the application of the method was developed.

The authors studied the use of vibroacoustic oscillations to increase the efficacy of complex therapy of periodontitis. The subjects of the study were 150 patients suffering from mild, moderate, or severe periodontitis. The results of the treatment were controlled using such clinicofunctional methods and indices as Schiller-Pisarev test, periodontal index, hygiene index, thermometry, rheoparodontography, and laser Doppler flowmetry. In treatment, "Vitaphon " device was used as the source of vibroacoustic oscillations. The authors developed the therapeutic technique and indications to treatment, and performed analysis of the therapeutic action of different vibroacoustic regimes. Considering the dynamics of patients' complaints and the results of clinicofunctional examinations, the study demonstrates therapeutic effects of vibroacoustic oscillations, such as periodontal blood flow acceleration, which, in turn, diminishes stagnation and improves trophic processes.

Wide use of local anesthetics (LA) in dentistry determines high incidence of side-reactions to them. The development of complications connected with the use of LA depends on the general condition of the patient (age, the presence of hepatic, renal, cardiovascular diseases, or high drug sensitivity), the degree of the anesthetic's toxicity, its dose and blood concentration, peculiarities of its pharmacokinetics, the technique of administration, the degree of tissue vascularization in the site of injection, as well as the presence of a vasoconstrictor and additive agents in its solution. Practice shows that there is cross sensitivity to drugs belonging to different pharmacological groups, which should be taken into account when administering LA. A dentist should remember about possibility of serious side-reactions to LA, and follow recommendations on their administration (doses, contraindications, and interaction), as well as take into account allergy background and be prepared to take necessary emergency measures in the event of complications.

Цель работы - изучить возможность применения химико-механического препарирования и ART-метода при лечении кариеса зубов у детей с расщелинами губы и неба, а также провести сравнительный анализ этих методик.
