[Assessment of morphological changes in oral mucosa in patients with gastrointestinal pathology].

Anatomical and functional proximity of oral and digestive tract organs as well as common mechanism of innervation and humoral regulation create prerequisites for the involvement of oral cavity in pathological processes developing in the gastrointestinal tract. Various gastric and duodenal substances affect oral tissues during frequent refluxes and produce lesions in epithelium of oral mucosa. Results of preliminary qualitative assessment of morphological changes in lingual mucosa are presented for patients with acid-dependent pathology.

[Concerning the criteria of expert assessment of unfavorable outcomes in implantological stomatology].

The state of complex forensic-medical expertise in implantological stomatology was analyzed in the article. The questions of assessment of medical aid quality with the use of score system of risk degree and factors determination are considered. The authors suggest to use the score system of unfavorable outcomes with the purpose of objectification of expert conclusions.

[New technologies and ways of endodontic-endoossal implantation improving].

There were developed, tested and used in practice new transdental implants (TDI) considerably widening the indications to endodontic-endoossal implantation. Universal TDI has a number of advantages over the known analogs and meant for osseointegration and fibro-osseointegration. The implant provides full tooth fixation in small bone volume, on maxilla including.

[The enhanced efficacy of endodontic endosseous and endosseous implantation using Hydroxyapol]. / Povyshenie éffektivnosti éndodontoéndoossal'noi i éndoossal'noi implantatsii s ispol'zovaniem gidroksiapol.

Hydroxyapol was used for intercanal-interosseous and intraosseous implantation. Operations were carried out in 62 patients with good results, this permitting the authors to recommend Hydroxyapol for practical implantations.

[The use of Hydroxyapol in filling in bone defects of the jaws and stimulating osteogenesis]. / Primenenie gidroksiapola pri vospolnenii kostnykh defektov cheliustei i stimuliatsii osteogeneza.

Hydroxyapol, a Russian biocomposite material, was used to repair defects of the jaw bones after resection of dental apices, cystectomy, and cystotomy in 102 patients. A more rapid formation of bone tissue and better stability of teeth were observed, in comparison with the patients treated traditionally, in whom the formation of a blood clot was the basis of osteointegration. Hydroxyapol is an effective means of osteogenesis, characterized by an anti-inflammatory effect.

[Changes in the oral microflora under the influence of pulsed periodic CO2 laser radiation in operations on the jaw bones]. / Izmenenie mikroflory polosti rta pod vozdeistviem impul'sno-periodicheskogo CO2-lazernogo izlucheniia pri operatsiiakh na cheliustnykh kostiakh.

Effects of pulsed periodical laser exposure on oral microflora were studied. Bacterial growth was suppressed immediately after surgery if pulsed periodical CO2 laser was used. Later only quantitative changes in the bacterial composition were observed. Asepticism of laser radiation does not depend on the discreteness of laser beam, radiation frequency, pulse duration, but depended on the radiation power, exposure duration, and area of exposure.
